10 Full-Size Liquids You Can Actually Take Through Airport Security

By Rachel Chang

For the better part of two decades, we’ve limited the liquids we carry through airport security. The magic number settled upon was 3.4 ounces, or 100 milliliters, of liquid in a container—an amount that became an  international standard developed by explosives experts . 

As frequent travelers are well aware, bottles that are 3.4 ounces or less can be stashed into a single one-quart plastic bag, and each traveler is allowed one—in a rule that’s been dubbed the 3-1-1 liquids rule. Oversized liquids can still be packed, but need to go into checked-in baggage.

But as screening devices have become more savvy, there has been talk of those limits being eliminated, especially as a  recent report said the UK will scrap the rules by 2024. “The introduction of new technologies has played a significant role in how aviation security has evolved over the past 20 years, thanks to strong industry partnerships and TSA’s agility in adopting technology that enhances security and improves the passenger experience,” a TSA spokesperson says. While there’s no timeline in place yet, the agency “anticipates the limit on liquids will be lifted in the coming years.”

So in the short run, travelers still need to limit the fluids they pack in carry-ons. But, as with all rules, there are exceptions. “TSA requires additional screening to ensure the safety of these liquids,” the spokesperson says of the items. “Travelers in this group should notify security of their medically-necessary liquids.”

In general, those  exceptions need to pass a three-prong test . They need to be required during the duration of your flight or at your destination, they can’t be available at the airport in the area past security, and they can’t be available at the destination. But when it comes down to it, the  TSA says on its site , “The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.”

Here are some of the most common exceptions of oversized liquids that can be taken through security. 

Prescription liquids, creams, and gels

Medication that has been prescribed specifically for you is perhaps the most common item that qualifies as an exception. TSA recommends that it’s clearly labeled so there's no question about what is inside. “You are responsible for displaying, handling, and repacking the medication when screening is required,” the agency’s site dictates. Depending on the situation, medication can either be screened visually or with an x-ray machine. It may also be tested for traces of explosives.

In some situations where the officers aren’t able to properly screen the item, you may be asked to open the container and transfer it to an empty container to test, or possibly dispose of a small quantity. 

In cases where you would like to make sure the medication isn’t opened or X-rayed, simply inform the TSA officer. “Additional steps will be taken to clear the liquid and you will undergo additional screening procedures to include a pat-down and screening of other carry-on property,” the site says.

Liquid medications and contact lens solution

In general,  liquid medications that are not prescriptions and  contact lens solutions are limited to 3.4 ounces, but TSA does allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip,” with the caveat you must declare them to security officers first. 

Breast milk and infant formula

Passengers traveling with infants have enough to worry about on their flights—and being able to provide the little ones with the proper nourishment should not be one of those concerns. Technically, TSA categorizes  breast milk and  baby formula as “medically necessary liquids.” The child doesn’t need to be present for the exception. 

In order to expedite the process, TSA suggests—but doesn't require—that the liquids be transported in clear and translucent bottles, so that they can be screened by the Bottle Liquid Scanners. (Those in pouches may not be able to.) While there is a chance you may be asked to open them, nothing will ever be placed in the liquid. The agency also adds that the screening process shouldn't affect the formula, but if you prefer they not be x-rayed, alternative testing means can be taken.

Baby and toddler food and drinks

In addition to breast milk and formula, food and drinks for babies and toddlers are also allowed, including puree pouches. They also technically fall into the “medically necessary” category.  Water for babies is also allowed in “reasonable quantities.” 

Liquid teethers

TSA also recognizes how important teethers are to babies and has “ liquid-filled teethers ” specifically called out as an item that can be brought through the security check.

Ice, gel, and freezer packs and other accessories to medically necessary items

Ice, gel , and freezer packs that are required to keep other medically necessary items in their required cool state are also exceptions, no matter what state they are in (solid ice or liquid gel). Additionally, IV bags or other accessories to medical supplies are also allowed. 

Hand sanitizer 

In the age of the COVID-19 pandemic, one major allowance was added to the list— hand sanitizer . While they may be readily available beyond security check and at your destination, the hygiene item was added, especially for use on the plane, as some experts have said that extra precautions should be taken on airplanes and airports to prevent the spread of germs .

Until further notice, hand sanitizers of up to 12 ounces are allowed since “TSA understands that COVID-19 is at the forefront on the minds of travelers, as health officials are encouraging that individuals wash their hands frequently,” the  site says . 

Live fish in water

Assuming your  live fish in water needs more than 3.4 ounces of water, this is another exception to the rule, as long as they’re in a clear transparent containers and properly inspected by the TSA officer. 

Biological specimens 

Liquid exceptions can be made in the name of science.  Non-infectious specimens in preservative solution can be carried through if it’s for scientific research. But they’ll need to be very specifically packed.

There can be up to 30 milliliters of free liquid in a heat-sealed inner plastic bag and then no more than one liter in the outer packaging, which needs to be marked: "Scientific research specimens, 49 CFR 173.4b applies." (Specific instructions for the regulation are  here .)

Duty-free purchased items in officially sealed bags

Shopping at the airport? Those liquid souvenirs can be taken home as well, as long as they are properly sealed by the cashier in a  security tamper-evident bag (STEB). The system was “developed to allow an exemption" to liquid volume rules for items purchased at duty-free airport retailers or on board an aircraft, according to the  International Civil Aviation Organization .

Here's the 411 on the TSA's 3-1-1 liquids rule

We've all been there. Waiting in the Transportation Security Administration line only to hear agents call for a "bag check," often because a traveler had a liquid product in their carry-on that's over the allowed limit (or some sort of other prohibited item).

It's a process that can sure slow things down, particularly on the busiest travel days. As you pack for your trip and consider what to put in your carry-on or checked luggage, it's important to consider what the TSA's limits are for liquids and similar products.

Since September 2006, the TSA has gone by the 3-1-1 rule when it comes to those types of products, including items like toothpaste, shampoo, conditioner, mouthwash and lotion -- sunscreen included.

For more TPG news delivered each morning to your inbox, sign up for our daily newsletter .

In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").

If you meet those requirements, you should get through security without issue. However, if your liquid items are larger than 3.4 ounces each, you'll have to leave them in your checked bag.

There are a few exceptions, though.

The TSA has kept in place a temporary pandemic exception to the rule, allowing up to 12 ounces of liquid hand sanitizer in carry-on baggage.

Part of this exception: The hand sanitizer will have to be screened separately since it's technically over the limit. You'll need to remove it from your bag before it goes through the scanner.

There are also exceptions for larger amounts of medically necessary liquids, gels and aerosols. You can bring those products in larger, "reasonable" quantities, the TSA's website says. However, you must declare those items to security officers at the checkpoint for inspection.

This could, obviously, take a little more time than if you're traveling without those items.

This exception doesn't include sunscreen, despite calls to relax sunscreen restrictions at TSA checkpoints. Like other liquid products, sunscreen bottles over 3.4 ounces must go in your checked luggage.

There are also many liquids you cannot bring with you .

You can bring creamy cheeses, liquid chocolate, liquid coffee, creamy dips and spreads, gravy, honey, hummus, ice cream, jam, jelly, juice, syrup, peanut butter, salad dressing, sauce, salsa, soda, soup and yogurt as long as they are in a container of less than 3.4 ounces according to the TSA .

Related: Should you get TSA PreCheck or Clear — or both?

And yes, you can bring your water bottle with you, even if it weighs more than 3.4 ounces — as long as it's empty. This can also be a great way to save money at the airport, since -- as the TSA points out -- many airports have filling stations for reusable water bottles.

When in doubt, consult the TSA's list of what you can carry through the airport and check with your airline.

TSA Liquid Rules Ultimate Guide (3-1-1 Explained) [2023]

Bringing your liquids through airport security is not always as straightforward as you might think.

There are several rules that apply when bringing your liquids through airport security checkpoints and, yes, many are obvious to those of us blessed with a shred of common sense.

But in some cases there are some less obvious restrictions that could apply to your liquids.

And when you start talking about things like baby essentials, medications, and liquids like alcohol, there are many lesser-known rules and exceptions that come into play.

Violating these rules can sometimes mean slowing down the flow of the screening checkpoint (something we all should want to avoid) but in other cases it could mean violating the law and you basically becoming an airport criminal.

And nobody wants that.

So it’s a good idea to get acquainted with how these rules work and in this article, I’ll give you a detailed breakdown of the 3-1-1 rule and also talk about the many different types of exceptions and additional rules that apply to different types of liquids such as medications and alcohol.

What is the TSA Liquids “3-1-1 Rule?”

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

Where does the 3-1-1 come from?

It’s just an easy way to memorize the different requirements that make up the rule and I’ll hit on those below.

3.4 fluid ounces or (100 mL)

The “three” indicates that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 ml).

(TSA uses 3.4 ounces because it’s easier to remember but really  100 ml comes out to 3.3814 fluid ounces. )

One of the biggest things that people get confused about is that the 3.4 ounce requirement applies to the size of the container and not the liquid within the container.

So let’s say that you have a 6 ounce container with only 2 ounces of fluid inside.

You may think that because you have under 3.4 fluid ounces of liquid, you are good to go but because your container is larger than 3.4 ounces, you cannot bring that through TSA.

The other big thing to know is that this refers to fluid ounces which relates to volume and is very different from ounces used for weight.

Some products like honey could weigh 4 ounces but still fit inside of a 3.4 fluid ounce container. It helps to know how to convert ounces/grams to fluid ounces .

1 quart-sized resealable bag

The first “one” means that your liquids must fit within 1 quart-sized resealable bag. Typically, this will be a clear Ziploc bag which just makes things easy for everybody.

The key thing to note here is that the containers must fit “comfortably” inside this resealable bag.

What does “comfortably” mean?

It basically just means that the bag is not bursting at the seams. (Think about how a pair of jeans should fit when you’re being honest with yourself about your waist size.)

If you are not able to easily reseal your bag, then your contents may not be fitting comfortably inside.

In such a scenario, it’s possible that a TSA agent could ask you to throw something out in order to allow your bag to comply with the rules.

In my personal experience, I have not seen a lot of TSA agents enforce the “comfortable” requirement very strictly but if you have bottles poking out of your liquids bag, I could see that being an issue.

1 quart size bag per person

The last requirement is that you are allowed 1 quart size bag per person.

The easiest way to comply with this is to simply separate your liquids bag from your carry-on and have one liquids bag in your bin when going through security.

Otherwise, it could look like you are trying to bring through two bags of liquids.

The best packing tip I have for this is to keep your liquids bag at the top of your carry-on so that you can easily retrieve it.

There’s nothing worse than scrambling to find that liquids bag while trying to get ready to go through a screening checkpoint.

TSA Pre-Check liquids rule

TSA Pre-Check allows you to bypass the main security line and pass through a screening line that is usually much shorter and quicker. This also means avoiding the full body scanner in many cases. It basically makes you a VIP when it comes to airport security checkpoints.

If you have TSA Pre-Check , you can take advantage of several benefits including things like:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids (3-1-1) can stay in bag

That last perk is the most relevant to the liquids rule as you will not have to remove your liquids bag and place them in one of the bins when going through security. You can simply leave them in your carry-on and pass through the metal detector without any issue.

I highly recommend that you look into getting Pre-Check in order to expedite your security screening. It will only cost $78 for five years and all you have to do is pass a background check. You can also get it if you are approved for Global Entry ( read how to get approved here ).

New hand sanitizer liquids rule

Due to the ongoing threat of coronavirus and the potential threat of spreading germs throughout airports and aircraft, TSA recently implemented a change with respect to hand sanitizer.

Passengers will now be allowed to bring one hand sanitizer bottle up to 12 ounces. These larger bottles will be screened separately so just be aware that it could add some extra time.

What exactly is a “liquid?”

In some cases, what constitutes a liquid will be very clear.

For example, it’s pretty much common sense that water inside of a water bottle is a liquid. The same applies for cologne, mouthwash, etc.

But liquids also can include less-obvious forms like aerosols, gels, creams, or pastes.

This means that several common items you would be bringing along for your trip could be considered a liquid like: toothpaste , lotion , sunscreen, shaving cream, shampoo , conditioner, and others.

You can find travel-sized products for most of these so it’s usually pretty easy to bring along items that comply with the TSA liquids rule.

Other items

You need to be mindful of other items that could be considered liquids like deodorant . For example, the following types of deodorants will be subject to the 3-1-1 rule:

• and Roll-On deodorants

Prohibited items

Just because you have something like an aerosol and it is in a container no larger than 3.4 ounces, that does not mean that you can bring it as a carry-on.

There are quite a few prohibited items like aerosol insecticide, bear spray, etc. that are not allowed as carry-ons. In fact, some of those items may not even be allowed on the plane at all. This is a good place to search if you are in doubt about whether or not you can bring a particular item.

Be aware that some items like hairspray may even have size restrictions when packed in your checked baggage.

Foods can also be liquids

One aspect of the TSA liquids rule that throws a lot of people off is that they forget many foods also qualify as liquids.

Here is a non-exhaustive list of food items that will fall under the liquids rule:

• Liquid chocolate
• Creamy dips and spreads
• Mashed fruits such as applesauce
• Jam and jelly
• Maple syrup
• Oils and vinegars
• Peanut butter
• Wet pet food
• Salad dressing
• Salsa and sauces

Basically anything that is usually poured, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

If your food is solid on the other hand , chances are you can bring it through.

TSA rules for liquid medications

The liquids rule provides exceptions for medical supplies and medications .

TSA allows larger amounts of medically necessary liquids, gels, and aerosols in “reasonable quantities” than your 3-1-1 allowance.

You do not have to have a prescription for these items but keep in mind that you need to comply with state laws regarding prescriptions and controlled substances.

This leaves two questions often to be asked and answered.

The first is what is considered “medically necessary?”

For example, is contact lens solution medically necessary?

It seems the answer to that is probably yes given the TSA states, they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip” on the page regarding contact lenses.

So if in doubt check the website and then inquire with AskTSA if you still don’t know.

The second question is what is considered a “reasonable quantity?”

What is deemed as a reasonable quantity is a subjective determination.

According to the TSA, you should bring what’s necessary for the duration of your trip (e.g., seven days) plus a day or two just in case things get delayed or canceled.

If you stick to what you think will be necessary for the duration of your trip, I don’t think you will often run into trouble. But if you’re bringing a six month supply of medication on a four day getaway, that’s when you might start to run into trouble if questioned.

TSA states that you must declare them to TSA officers at the checkpoint for inspection.

You also want to remove these from your carry-on so that they can be screened separately from your belongings. (You do not have to put your liquid medication in a plastic Ziploc bag.)

Just be aware that if one of your liquid items declared as medically necessary sets off the alarm, it may require additional screening and may not be allowed.

Baby essentials

You are allowed to bring formula, breastmilk, and juice for infants or toddlers in “reasonable quantities” through airport security. According to the TSA, reasonable quantities for baby essentials typically means the duration of the flight.

When bringing these items through security, be sure to separate these from your carry-on bag so that they can be screened separately from the rest of your items.

If you are carrying liquids in excess of 3.4 ounces, you are advised to inform the TSA officer at the beginning of the screening process that you have excess liquids. You can do this when you are unloading your items into the bin.

In many cases, excess liquids will be screened by x-ray.

It’s also possible that an officer may ask you to open up the container and potentially even transfer a small quantity of the liquid for testing.

If you are worried about the effects of an x-ray machine on your liquids, The Food and Drug Administration states that there are no known adverse effects from eating food, drinking beverages and using medicine screened by X-ray.

If that is not good enough assurance for you, you can ask to avoid the x-ray machine.

Additional steps may be able to be taken to clear the liquid but the traveler will likely have to undergo additional screening procedures which could include a pat down and a thorough screening of all of your carry-on property.

You will also be allowed to bring along ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk and juice.

If these are in a partially frozen state or perhaps appear like a slushy they will be subject to the same screening as described above.

Other permitted baby items include gel or liquid-filled teethers, canned, jarred and processed baby food.

Just always be aware that these items may have to undergo additional screening.

TSA liquid rules for alcohol

Bringing alcohol through TSA presents a number of different challenges.

First, your alcohol in most cases will have to comply with the liquids 3-1-1 rule. This means that you won’t be able to bring in regular bottles of liquor or beer.

It is possible to find small bottles that are under 3.4 ounces (mini-liquor bottles are often around 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid).

But contrary to what many people think, it’s also permitted to bring your own alcohol in one of your own containers.

The catch is that there are specific restrictions about what type of alcohol is allowed on board and that can be allowed as a carry-on. You really need to make sure that you are abiding by these rules because you could be violating federal law otherwise.

The first regulation to know is that alcohol beverages with an alcoholic percentage above 70% (140 proof) is never allowed on the plane . In fact, alcohol with such a high alcohol percentage is considered a hazardous material.

If the alcohol content is above 24% but not above 70% then the alcoholic beverage must be in its retail packaging. A lot of popular alcoholic beverages for within this range. Here are some  ranges  for the alcoholic content of some common beverages:

Alcohol Percentage Content

• Vodka | ABV: 40-95%
• Gin | ABV: 36-50%
• Rum | ABV: 36-50%
• Whiskey | ABV: 36-50%
• Tequila | ABV: 50-51%
• Liqueurs | ABV: 15%
• Fortified Wine | ABV: 16-24%
• Unfortified Wine | ABV: 14-16%
• Beer | ABV: 4-8%
• Malt Beverage | ABV: 15%

And finally, one of the most important things to remember is that you are not allowed to serve yourself your own alcohol when flying.

Instead, you must request a flight attendant to serve you the alcohol or else you will be violating FAA regulations. Some flight attendants will happily serve you your own beverage but others will not be so inclined.

If you purchased alcohol at duty free store, different rules apply in that scenario. Basically, you can bring your duty free alcohol through TSA security but you have to comply with three separate requirements:

• The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
• The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
• The original receipt for the liquids is present and the purchase was made within 48 hours.

Read more about this rule  here .

Checked baggage liquid rules

Many times, you can simply place your liquids in your checked baggage and not have to worry about that pesky 3-1-1 rule.

This is usually the way to go on longer trips when you might be bringing large quantities of things like shampoo or shaving cream.

But as mentioned above, you still need to make sure that the type of liquid is allowed on a plane. Certain materials may be considered hazardous and you could be violating the law by bringing those on board.

If you are loading up your checked baggage with a bunch of liquids, make sure that you double bag if there is potential for the liquids to spill!

TSA Liquid Rules FAQ

The TSA 3-1-1 rule does not apply to checked baggage. However, there are some restrictions on what liquids can be transported in your checked baggage. There may also be limitations on the quantity of liquids when it comes to importing large quantities of things like alcohol. At some point, you might have to obtain a license for certain goods.

TSA definitely enforces the liquids rule and I would recommend not trying to circumvent the rule. It’s possible that an agent may be more lenient than another in certain circumstances but I would always assume that an agent will be enforcing strictly so that I don’t run into any unexpected issues.

TSA has the rules in order to detect potential explosives and other harmful materials that exist in liquid state.

The same liquid rules apply for both domestic flights and international flights. One difference that you might encounter is when you purchase duty free goods before an international flight. See the duty-free section above for more details. Also, when flying internationally it is recommended that you get to the airport extra early. It is possible that you could get hit with SSSS and be forced to undergo a heightened security screening, so always plan out extra time.

While you might view your makeup as special, there are no special rules for your makeup when it comes to TSA. They must abide by the same 3-1-1 rule explained above. Read more about makeup rules here.

No, you do not have to take out your liquids if you have TSA Pre-Check.

The same TSA liquids rule will apply to all airlines. So if you’re flying American or Delta, the rules will be the same as if you were flying Southwest or United. With that said, some airlines do have some differences in how they handle acceptable baggage so you should make sure to read up on the latest baggage policies for the airlines.

If you are traveling from an “international last-point-of-departure” to the U.S ., powder-based substances in carry-on baggage greater than 350mL or 12 oz. may require additional screening. If your substance is over 12 ounces and cannot be cleared it will not be allowed onto the aircraft cabin. TSA recommends that you transport powders in your checked baggage.

TSA has several rules you need to follow when it comes to drinking liquids through airport security. The most well-known is the 3-1-1 rule but there are other considerations you need to think about like foods that might trigger the rule and exceptions for medical and baby essentials. In the end, try to be as reasonable as possible with what you are bringing through and you will run into few problems.

Everything You Need to Know About the TSA’s Liquid Limit

The tsa allows liquids under 3.4 ounces in your carry-on—but what’s considered a “liquid” isn’t always obvious..

• Copy Link copied

Don’t forget to remove your liquids when going through TSA screening.

Whether you’re a carry-on-only kind of person or not , knowing the Transportation Security Administration’s (TSA) liquid limits is essential for anyone who travels by plane in the United States. Yet understanding which of your toiletries, foods, and other items even count as “liquid”—let alone how best to pack them—can get confusing. Use this guide to understand the TSA’s rules and restrictions about liquids, common exceptions, and tips to help ensure your next airport security screening goes smoothly.

What is the TSA liquid limit?

The TSA’s liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person , or roughly nine 3.4-ounce containers in a single quart-sized bag. Anything more will have to go in a checked bag or risk being tossed out.

If your liquids are stored in containers larger than 3.4 ounces, even if there’s only 3.4 ounces left inside the bottle, you can’t bring them through security.

Completely empty bottles, such as your reusable water bottle , are allowed through the TSA checkpoint since (spoiler alert!) they don’t contain any liquids at that moment.

Which toiletries TSA allows in your carry-on

The TSA allows all of the following common toiletries in your carry-on only in containers that are 3.4 ounces or less:

• Shampoos and conditioners
• Lotions and sunscreen
• Gel hair products

In other words: yes, you can bring toothpaste, deodorant, and sunscreen through TSA checkpoints but only if they are in travel-sized containers.

Powders and powder-like substances, including baby powder and some makeup items, aren’t restricted in your carry-on bag. But if you’re carrying more than 12 ounces (350 milliliters) of a powder, you’ll need to place it in a separate bin for X-ray screening, and it may be subject to additional screening—so it’s a good idea to budget an extra few minutes at the security checkpoint if you think this might happen.

Tips for packing your toiletries in your carry-on

To comply with TSA regulations, invest in small, reusable toiletry bottles, like these capsules by Cadence.

Especially if you don’t have TSA PreCheck , it’s helpful to pack all of your toiletries in a quart-sized (or smaller) clear plastic toiletry bag for screening. Although improved airport technology means that far fewer air passengers (both in PreCheck and non-PreCheck lines) will have to take their liquids out out of their carry-on, it’s still helpful to have all of your liquids in one bag just in case you get pulled aside for additional screening. For an upgrade from that large Ziplock, we recommend the standard-sized Clarity Jetset Case from Truffle ($88), which has a clear window panel and is comparable in size to a quart-sized bag.

Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that’s not subject to the 3-1-1 rule. We like Humankind’s fluoride toothpaste tablets ($12), which resemble small mints and turn to paste when you crush them between your teeth. Matador has also recently released a reusable toothpaste tube ($10), which you can fill (and refill) with your regular toothpaste.

For travel toiletries that are easy to rebottle (like shampoo or body wash), consider investing in reusable bottles or containers so you can always keep your preferred brand on hand. Some of our favorite TSA-approved toiletry bottles include:

Buy Now: GoToob three-pack of 3.4-ounce bottles, $30, rei.com

These easy-to-fill, leakproof silicone tubes are ideal for shampoos, conditioners, lotions, and body washes. GoToob’s line comes in a variety of sizes, ranging from 1.7 to 6 ounces, and are easy to clean between refills.

Matador FlatPack

Buy Now: $13 for one or $35 for three, matadorup.com

Each three-ounce, TSA-approved bottle is made from a durable, waterproof, nylon-based fabric. Like GoToob, they’re leakproof and easy to fill, but thanks to their flexible, fabric-like design, they will shrink to their contents, taking up less space in your pack. >> Read the full review of the Matador FlatPack

The refillable travel containers by Cadence are small, leakproof “capsules” that click together with magnets. At 0.56 ounces, they’re best for makeup and toiletries you don’t need much of—like a weekend’s worth of shampoo or a week of that under eye cream you only need a dab of.

Foods are subject to liquid limits

The TSA’s 3-1-1 rule applies to food too, meaning you’ll need to make sure any foods that count as liquids, gels, or pastes (like yogurt, peanut butter, pâté, jams, or that tasty pimento cheese spread you tried to bring home from Charleston) are less than 3.4 ounces or packed in your checked bag. There are some exceptions, like frozen foods and juice for babies, and the TSA’s website is the best resource to check for specific items.

Exceptions to TSA’s liquids rule: Full-sized liquids that you can bring through security

The TSA has several important exemptions to its liquids rule. You’re allowed to bring full-sized bottles of the following:

Hand sanitizer: Due to the coronavirus pandemic, the TSA currently allows travelers to bring up to 12 ounces of hand sanitizer in their carry-on bags. These will be screened separately.

Medication: You’re allowed to bring medically necessary liquids, aerosols, and gels through security. This also includes the ice or gel packs you may need to keep your medications cool. You are not required to store these items in a plastic, resealable bag, but you should remove them from your luggage and let the TSA officer know what you’ve packed.

Baby formula and breast milk: Like medication, you can bring freezer packs to keep these items cool, and you should remove them from your luggage and notify an agent when you go through security. More baby-related exceptions? Gel or liquid-filled teethers and canned or jarred baby food.

Of course, the final decision on whether an item is allowed through the checkpoint rests with the TSA officer.

If you’re ever unsure about a specific item, the TSA’s website has a handy, searchable list of prohibited and allowed items worth checking before you travel. You can also now text the TSA with your questions.

Everything You Need to Know About TSA Liquid Rules

Here's what to know before you fly with shampoo, medication, or any other liquids you may need during your travels.

Dealing with airport security can be one of the more daunting aspects of air travel , from the detailed rules about what you can and can't bring on board to the long lines that often form at checkpoints.

One rule that frequently trips up travelers is the Transportation Security Administration's (TSA) 3-1-1 regarding liquids in carry-on bags . We're here to walk you through the finer details of the rule and provide helpful tips for packing liquids when you're flying.

What is the TSA's 3-1-1 rule?

In 2006, British security officials thwarted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies around the world have limited the amount of liquid passengers can bring through airport security.

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.

The 3-1-1 designation is a simple way to remember these numbers: individual liquid containers must be 3.4 ounces or smaller, they must fit into one clear, quart-size bag, and there is only one bag allowed per passenger.

Liquids that do not comply with the 3-1-1 rule must be packed in checked bags, or thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited entirely, both in checked and carry-on bags. You can find a full list of permitted and prohibited items on the TSA's website .

If you're unsure if a specific item adheres to the 3-1-1 rule, you can always contact the TSA before your trip. "Tweet your questions and comments to @AskTSA or via Facebook Messenger , weekdays from 8 a.m. to 6 p.m. ET," TSA spokesperson Jessica Mayle tells Travel + Leisure . "You can also call the TSA Contact Center at 866-289-9673."

Are there any exceptions to the 3-1-1 rule?

The TSA does exempt some items from the 3-1-1 rule: medically necessary liquids, formula, and breast milk. You can bring more than 3.4 ounces of these liquids on board, but you may have to undergo additional security screening.

"Inform the TSA officer at the beginning of the screening process that you're carrying them," says Mayle. "These liquids are typically screened by X-ray, but TSA officers may also test them separately for explosives or concealed prohibited items. Officers may ask you to open the container and/or have you transfer a small quantity of the liquid to a separate empty container, or dispose of a small quantity, if feasible."

If you don't want your exempt liquids to be screened by X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

And that's not all. "There's an exception for hand sanitizer, which has a temporary 12-ounce limit," says Mayle. But as COVID-19 travel restrictions and protocols continue to lift, the temporary special case for hand sanitizer could change, too.

Another exception is liquids purchased after security in an airport. In domestic U.S. airports , you can bring nonalcoholic drinks and other liquid items purchased airside onto your flight. (This is not always the case in international airports.) Duty-free liquids, however, will be sealed in a tamper-safe bag before boarding — sometimes they're permitted in the cabin, and other times they may be stowed elsewhere on the plane.

Packing Tips for Liquids in Carry-on Bags

• While many products are sold in 3.4-ounce containers suitable for travel, not all of them are. Consider rebottling your liquids into travel-size, leak-proof cases.
• "Another way to save space in your quart-sized bag is to pack solid versions of products, which you can put in your luggage or carry-on bag without needing to place it in the quart-size bag," travel advisor Ateet Ahuja of Complete Getaways tells T+ L. "For example, you can bring a stick or solid version of some perfumes and shampoo bars instead of liquid shampoo."
• Buy your liquids, like shampoo or mouthwash, at your final destination. "While you'll spend a little extra, the cost far outweighs the potential of it spilling or leaking in your bag," says Ahuja.
• On that note, prepare for spills — Ahuja advises wrapping a small hand towel around your quart-size bag.
• Pack your nonliquid toiletries separately to save space in your quart-sized bag.
• Pack your liquids bag in an easy-to-access space, like an external compartment or the top of your carry-on bag. According to Ahuja, "This will save you time in the TSA line."

TSA Liquids Rule Explained: What Size Liquid Can You Bring on a Plane?

What you can and can’t bring on a plane, including the amount allowed, can be very confusing for even the most experienced of flyers, especially when it comes to liquids.

According to TSA regulations, you are allowed to bring liquids in containers that don’t exceed 3.4oz/100ml in your carry on.

There are also limits when liquids are packed in your checked bags, which many people are not aware of, though the limits are much greater.

What Size Liquid Can You Take on a Plane?

Carry on bags.

The TSA has a rule in place called the 3-1-1 Rule .

The 3-1-1 Rule states that “each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters .”

These containers must also fit in a 1-quart sized, resealable bag.

You are required to take this bag out of your carry on and place it in a screening bin as you go through airport security.

Note that it is the size of the container itself and not how much liquid is in the container that matters.

So, if you have a bottle that contains just 1ml of liquid inside a 4oz container, it still won’t be allowed through.

Checked Bags

Not many passengers are aware that there are restrictions on the quantity of liquids you can pack in their checked bags.

According to the TSA:

• A container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
• The total aggregate quantity of your toiletry products must also not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces).

No Differences For International Flights

Even though it may not be called the 3-1-1 rule worldwide, the rules remain the same if you’re flying internationally.

So regardless if you’re flying from or within Mexico, Canada, the UK, Europe or any other country, you are only allowed to pack liquids (as well as gels and aerosols) in containers that are no larger than 3.4oz/100ml in your carry on.

Airlines Follow TSA Regulations

All airlines follow TSA regulations .

So this means that regardless if you’re flying with Delta, Southwest, American Airlines, JetBlue, or any other regional or major air carrier worldwide, you are only allowed to bring liquids in containers that do not exceed 3.4oz/100ml in your carry on.

How to Pack Liquids for Flying

There are a few guidelines you should follow to make your next flight go as smoothly as possible.

• Make sure that no container you want to bring is no larger than 3.4oz/100ml.
• Buy travel-friendly products of your favorite products.
• If the company doesn’t sell travel-friendly sizes, buy your own 3.4oz/100ml containers and transfer the liquids into them.
• Consider packing non-liquid alternatives instead (you can bring a bar of soap on a plane on a plane , for example, with no restrictions. The same applies to sunscreen sticks ).
• Share toiletry space with your travel partner, as the 3-1-1 Rule applies to each passenger.
• Store your items in a clear bag that is no larger than 1 quart.
• Use your checked luggage for liquids in larger containers.

You Will Be Able to Bring 7-8 Bottles in Your Carry On

In total, you can take 32 ounces (or 1 quart) of liquids on a plane.

But as the containers themselves will take up space in the single quart-sized bag, you won’t be able to take a full 32 ounces of liquids in your carry on.

You will be able to bring about 25 ounces in total, in 7 or 8 travel-sized 3.4oz/100ml containers onto a plane in your carry on.

How Many Ounces in Total Can You Take On a Plane?

Carry on bags.

As just mentioned, you can bring 32 ounces (or 1 quart of liquids on a plane), though it will more likely be 25 ounces in 7-8 bottles.

If liquids are packed in your checked bags, each container must not exceed 18 ounces or 17 fluid ounces).

The total aggregate quantity of your toiletry products must also not exceed 70 ounces or 68 fluid ounces.

A Loophole to Bring More Than 3.4 Oz/100ml On a Plane

There is a loophole that lets you bring more than 3.4oz/100ml of liquids on a plane, though it only works with very few items and under certain circumstances.

If you are traveling with a young child or baby, you can say that the item is for them.

Of course, this will only work for bringing a water bottle on a plane and not items like alcohol, coffee or tea . 

Exceptions to the 3-1-1 Rule

There are several exceptions to the 3-1-1 Rule.

The following items, if packed in your carry on bags, are allowed to exceed 3.4 oz/100ml:

• Breast milk and formula
• Liquid medication
• Hand sanitizer
• Jumbo disinfecting wipes
• STEB items (secure, tamper-evident bags purchased at the airport)
• Cough syrup
• Gel-filled bras
• Saline solution
• Ice packs (must be frozen solid)

Liquids That Are Forbidden

There are several liquids that, even if under 3.4 oz/100ml, you are not allowed to bring on a plane in either your carry on or checked bags.

These items include:

• Most flammable liquids ( you can bring nail polish on a plane , though)
• Most toxic liquids
• Aerosols that do not qualify as toiletries
• Alcoholic Beverages over 70% ABV (140 proof)
• Insecticide
• Spray Paint
• Spray Starch
• Cooking Spray

Surprising Items That Qualify As Liquids

There are also items that you wouldn’t expect to count as liquids, but actually do.

• Peanut butter
• Hair mousse
• Snow globes

What the 3-1-1 Rule Stands For

The 3-1-1 Rule stands for 3 ounces, 1 passenger, 1 quart-sized bag.

While the limit is actually 3.4 ounces instead of 3 ounces, we guess that 3.4-1-1 Rule didn’t have the same ring to it.

Why the 3-1-1 Rule Exists

The 3-1-1 Rule exists because terrorists have previously tried to sneak liquid explosives on a plane on more than one occasion.

While the rule is frustrating, it exists for the safety of passengers.

The 3-1-1 Rule: Simplified

The TSA liquid limit, known as the “3-1-1 rule,” is a crucial part of airport security measures. At first glance, it might seem a bit complex, but it’s quite straightforward when broken down. Here’s the deal: you can carry liquids, gels, and aerosols in travel-size containers, but each container must not exceed 3.4 ounces or 100 milliliters. Now, where do these containers go? They should all fit comfortably in one transparent, quart-size bag. This bag acts as a visual aid for TSA officers, speeding up the screening process.

But why exactly 3.4 ounces or 100 milliliters? This specific limit is based on security research and analysis, determining that these quantities are safe for air travel and unlikely to be used for harmful purposes. It’s a balance between security and convenience, ensuring passenger safety while allowing you to carry your essential items.

So, each passenger is allowed one quart-size bag for their small containers. Think of it as your mini travel kit. This rule applies across the board, whether you’re flying domestic or international, making it a standard to remember for all your travels.

Understanding and adhering to the 3-1-1 rule is your ticket to a smoother airport experience. It not only helps you pass through security checks more quickly but also contributes to the overall safety and efficiency of airport operations. Remember, a little preparation goes a long way in ensuring a hassle-free start to your journey!

A Look at the Numbers

Statistics reveal the extent of the challenge: For example, just in the year 2019, TSA officers intercepted over 13 million prohibited items , a significant number of which were liquids over the allowed limit.

This staggering figure highlights the need for awareness among travelers about TSA regulations.

TSA Administrator’s Insight

David Pekoske , the TSA Administrator, emphasizes the importance of knowing what to pack. He stated,

“Our goal is to ensure that all passengers understand what they can and cannot bring through security checkpoints to maintain a safe traveling environment.”

This advice is key to a hassle-free journey.

Beating the System – The Clever Way

Navigating TSA rules can feel like a game of strategy, and knowing the exceptions is like having the best cards in your hand. Interestingly, the TSA makes allowances for certain items that are crucial for health and childcare. Medications, baby formula, and breast milk are among the items exempt from the standard 3-1-1 liquid limits.

Let’s dive deeper into these exemptions:

• Medications : If you’re traveling with prescription or over-the-counter medications in liquid form, they don’t have to adhere to the 3.4-ounce restriction. This is particularly important for those with medical conditions requiring regular medication. Make sure your medicines are easily identifiable and present them to TSA officers for inspection. It’s also a good idea to have a copy of your prescription or a doctor’s note, just in case.
• Baby Formula and Breast Milk : Parents traveling with infants or toddlers can breathe a sigh of relief. Baby formula, breast milk, and juice for infants or toddlers are permitted in reasonable quantities. This means you can carry what’s necessary for your journey, even if it exceeds the standard limit. The key here is to declare these items at the checkpoint. TSA officers typically screen them separately to ensure they’re safe for travel.
• Special Dietary Needs : Similarly, if you have special dietary requirements that involve liquids, such as nutritional shakes or juices for medical purposes, these are also allowed under the same guidelines as medications.

But here’s a pro tip: while these items are exempt, organizing them for easy access and quick presentation at security checks can save you time and hassle. Keep them separate from your other liquids in your carry-on , and inform the TSA officer as soon as you reach the checkpoint. This proactive approach shows that you’re well-informed and helps the TSA do its job more efficiently.

In summary, the TSA’s allowances for certain essential items demonstrate their commitment to balancing security with the practical needs of travelers. By being aware of these exceptions and preparing accordingly, you can ‘beat the system’ in the most clever and hassle-free way possible. Remember, the goal is to ensure safety while accommodating the genuine needs of passengers – a win-win for everyone involved.

Calling All Travelers: These Are the Official TSA Liquid Rules

You don't want security to throw away your new, full-size bottle of shampoo do you?

Every item on this page was chosen by a Town & Country editor. We may earn commission on some of the items you choose to buy.

We've all fallen victim to TSA while traveling; here's a refresher so you don't make the same mistakes again.

TSA Liquid Rules:

According to the TSA website , these rules apply for liquids, aerosols, gels, creams, and pastes.

All liquids must be in a 3.4oz or smaller container. Your serums, creams, cleansers, and masks are too expensive to lose, so check their sizes and if they're too big, leave them at home or transfer them to a smaller container.

They have to be able to fit in a quart-size bag. Before you throw 10 containers of liquids into your carry-on, make sure that everything can fit in a quart-size bag. Think about what you really need for your trip, a la Marie Kondo , and remember you can always buy things once you arrive at your destination.

Powders must be in 12oz containers or smaller. TSA placed new restrictions on powders in 2018. Ensure that your makeup, protein powder, and baby powder are in containers within that range, or put them into a checked bag.

Anything else has to go into a checked bag. If you can't part with your full-size products, they have to go into a checked bag to avoid getting tossed into the TSA product graveyard. If you're looking to save money, share one checked bag with your whole group.

Only empty water bottles will pass the TSA checkpoint. If you bring a refillable water bottle, make sure it's empty before you approach security. You can fill it up after you go through the checkpoint or buy water in the terminal.

There are exemptions. If you use a medication that comes in liquid, aerosol, gel, cream, or paste form and the container is larger than 3.4oz, it's exempt from the above rules. Similarly, if you're carrying baby formula, breast milk, or other liquid foods for your child, these are also exempt.

Rules for Liquids in Checked Baggage: The Complete Guide

TripSavvy / Ashley DeLeon 

DIY Ways to Secure Your Packed Liquids

Go with the pros, add padding, anticipate inspections, tips for packing liquids in checked baggage.

You can carry liquids in checked baggage, but you will have to do some research and take precautions. First, you must find out which liquids are not allowed on airplanes regardless of where you pack them. The Transportation Security Administration (TSA) has a list of these prohibited liquids on its website . You should also look at the Federal Aviation Administration's list of hazardous materials. Never try to bring prohibited materials with you when you fly.

After you've done your research, you must determine whether you can bring the liquid items of your choosing to your destination. If you plan to carry several bottles of wine, for instance, you may not be able to bring them into certain U.S. states due to liquor import regulations. Travelers flying to or from Canada will want to read the Canadian air travel regulations, and visitors to the UK should read the United Kingdom's list of items you may carry in hand (carry-on) and hold (checked) baggage.

Your next step is to decide whether you want to pack colored liquids, such as red wine or nail polish, which could damage your clothing. Carrying any colored liquid can be risky. Decision-making factors include whether these items are available at your destination and whether your itinerary is flexible enough to allow you to purchase them locally, rather than bring those liquids with you.

Finally, you will need to carefully pack your liquid items so they will not break or leak. There are several ways to accomplish this. Read on for our complete guide on what to know before packing liquids for your next trip.

To prevent leaks, wrap the top of your bottle or container with duct tape so the cap stays on. (You may also want to pack a small pair of sharp scissors in your checked bag so you will be able to remove the tape later.) Put the container into a zipper-top plastic bag and seal the bag closed. Next, place that bag into a larger zipper-top bag and seal it closed, pressing out all the air as you do so. Wrap the whole thing in bubble wrap if the container is breakable. Finally, wrap that bundle in a towel or in clothing. (Many travelers suggest using dirty laundry for this.) Place the wrapped bottle or container in the middle of your largest suitcase, surrounded by clothing and other soft items.

A variation on this method involves using a hard-sided plastic or cardboard container to protect your liquid item. Use a small cardboard box or a sealed plastic container. Double-bag the liquid item as described above. Then, place it in the container and pad it with crushed newspapers, plastic air pillows or crumpled plastic grocery bags. Tape the box shut and pack it in the center of your suitcase.

You can buy styrofoam or bubble wrap "shippers," which are sealable padded bags. Brand names include the inflatable VinniBag or the Wine Mummy. Boxes made especially for transporting glass and liquid items are another option. Your local wine shop or pack-and-wrap store may carry shippers. Be aware that the bubble wrap bags will keep escaping liquid from staining your clothes, but may not prevent glass bottles from breaking. The box shipper will take up more room in your luggage. While it may not prevent liquid from escaping, the box shipper minimizes the risk of breakage.

Protect your liquid items by placing them in the middle of your suitcase, completely surrounded by clothing and other items. Be aware that your suitcase could be dropped or crushed, perhaps more than once, on its way to your destination. It may even be dragged on the ground behind a luggage cart. If you can choose from several suitcases, pick the one with the stiffest sides and pack it as tightly as you can to better cushion your liquid items.

If you pack liquid items in your checked bag, assume that your bag will be inspected by a baggage security screener. The screening officer will see your liquid item on the baggage scanner and will probably need to take a closer look at it. Do not pack valuables, even liquid ones, or prescription drugs in your checked baggage.

• Careful packing and padding will increase your chances of success, so make sure to transfer all liquids to leak-proof containers.
• Pare down your packing. Not everything can fit in your suitcase! Decide what toiletries you may find up for grabs in your hotel room, and edit, edit, edit.
• Two-in-one items are always a good idea.
• If you have a large-sized soap or shampoo that you really want to take on your trip, invest in travel-sized toiletry bottles . This way, you can pour some into the correctly sized bottle and still be allowed to take it with you on your trip.

Delta Carry-On Size, Liquid Policy & Other Important Restrictions

If you want to avoid checking a bag or paying extra fees on Delta, you need to read this!

Delta Carry-On Size (Dimensions)

Weight restrictions for carry-on bags, weight restrictions for checked luggage, my recommended carry-on, rules for “special items”, delta personal item size, delta connection flights, the tsa 3-1-1 rule, delta food policy, delta airlines carry-on policy: pet fees, tsa-approved pet carrier for delta airlines, prohibited items:, restricted items:, frequently asked questions about delta’s carry-on policy.

If you have an upcoming flight with Delta and are planning to travel with just carry-on luggage , you’ll need to be up to speed with Delta’s carry-on policies.  Each airline’s rules are slightly different, so don’t just assume that what works for one will work for all airlines.

In this article, we’ll explain everything you need to know about Delta’s carry-on policy. This includes Delta’s carry-on size and weight limits, liquid policy, personal items, pets, and prohibited items.

Delta Airlines Carry-On Rules

Delta allows you to bring one carry-on bag and one personal item onboard with you at no additional charge. The only restriction is that your personal item must be small enough to fit under the seat in front of you.

Delta’s carry-on bag size limit is 22″ x 14″ x 9″. These dimensions include the wheels and handles of your carry-on bag.

If you aren’t sure what size your carry-on is, Delta has carry-on sizers located near the ticket counter.  These templates will help you make sure your carry on bag will fit in the overhead bin before you get to the gate.

As a rule, Delta doesn’t impose weight restrictions on a carry-on bag.   But there are a couple of international exceptions to this rule, including:

• Singapore – Changi International Airport (SIN): Carry-on bags cannot exceed 15 lbs. (7kgs)
• Beijing – Capital International Airport (PEK): Carry-on bags cannot exceed 22lbs. (10kgs)
• Shanghai – Pudong International Airport (PVG): Carry-on bags cannot exceed 22lbs. (10kgs)

I fly Delta almost every week into and out of many airports and I have never had them weigh my carry on bag for domestic or international flights. I have not flown to Singapore, Beijing or Shanghai on Delta, so I can’t speak to the weight restrictions on those routes.

Weight restrictions with checked luggage vary by cabin, destination, and medallion status. The general rule of thumb is if you don’t have medallion status you are allowed up to a 50 lb. weight limit per bag. If you have Delta medallion status, you are allowed up to 70 lbs. per bag for domestic flights and 50 lbs. per bag for international flights.

However, Delta One, First, and Business passengers are allowed up to 70 lb limit per piece regardless of Medallion status.

If you are looking for a great carry-on bag when flying Delta, I recommend the Travelpro Maxlite 5 Expandable Spinner. I have used this carry-on for years and brought it with me on many Delta flights.

It’s durable, reasonably priced, and holds everything I need for shorter trips (3-4 days). Plus the spinner wheels make it very easy to get through the airport quickly and effortlessly.

This carry-on bag has been sizer bin tested to accommodate overhead bin space on most major US airlines.

Case Dimensions:

• H: 21 in. W: 14 in. D: 9 in.

Note: If fully expanded it may not meet overhead bin size limits, so be careful to not overpack.

Delta will allow you to travel with some “special items” which do not meet their checked or carry-on size or weight dimensions. You will want to talk with the gate agent upon checking in to address the needs and characteristics of your special item. The gate agent will help you check your special item and determine if any extra fees will apply.

“Special items” may include:

• Strollers and Child safety seats
• Sporting Equipment
• Musical Instruments
• Medical Equipment & Wheelchairs
• Fragile items
• Perishable Items & Imported Merchandise

Delta’s carry-on policy allows you to travel with a free personal item in addition to one piece of carry-on luggage. Personal items include a purse, briefcase, laptop, backpack, blanket, shopping bag, or a similar-sized item.

Personal items must be able to fit under the seat in front of you. Underseat dimensions are 20 x 15 x 11 inches (55 x 38 x 28cm) on most Delta aircraft.

In addition to your carry-on bag and personal item, you can bring the following items with you:

• A jacket and umbrella
• Food or drink purchased after clearing the security checkpoint
• Duty-free merchandise
• Special items like strollers, child restraint seats, or assistive devices such as wheelchairs or crutches

If you happen to be flying on a Delta Connection flight with fifty seats or less (such as a CRJ 200), Delta’s policy states that you can bring a personal item with you, but not a carry-on bag, due to limited overhead space.  Personal items must be able to fit under the seat in front of the passenger.

All carry-on bags within Delta’s size restrictions will be gate checked, free of charge, during the boarding process and returned upon deplaning.   

However, despite this “official rule” there are some bags you can carry on a regional jet.  Check out our article on the best carry-on luggage for regional jets for a list of options, including under-seat luggage.

Delta Liquid Policy

The rules for carry-on liquids are set by the TSA (Transportation Security Administration), not by the airline.  Delta doesn’t have its own specific Liquids Policy, they just enforce the rules and policies of the TSA.

It’s also important to note that the rules for bringing a “liquid” in your carry-on bag differ from those that govern what you can bring in your checked luggage. Liquids in a carry-on bag must be 3.4 ounces or smaller and fit in a 1 quart-sized container. Anything larger must be placed in your checked luggage.

• All liquids, gels, pastes, and aerosols must be in a container of 3.4 ounces or smaller.
• All liquids must be in a resealable quart-sized clear plastic bag removed from your carry-on during the TSA screening process. 
• Special exceptions are in place for items such as medication, formula, breast milk, etc.
• Food and Drinks purchased once you have cleared TSA checkpoints are not included in these restrictions.

The TSA 3-1-1 rule provides the parameters for how passengers can bring liquids on an airplane in their carry-on.

Each passenger may carry liquids, gels, and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters and are enclosed in a sealed one-quart-size bag. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste , shampoo, conditioner, perfume , mouthwash, deodorant , and lotion.

Any liquid that does not meet the TSA 3-1-1 rule will either have to be checked with your luggage or will be thrown away at the security checkpoint.

Exceptions to this rule are certain medications and baby food/child nourishment .

The TSA also sets the rules for what type of food you can bring on the plane . There are two different scenarios pertaining to food: 

• The food you bring with you from home, and
• The food you buy at the airport after you have gone through security.

When bringing food with you from home, an important thing to note is the classification of liquid vs. solid foods.  

The general rule is “If you can spill it, spread it, spray it, pump it, or pour it, then it’s considered a liquid or gel”.   This means your food may be considered a liquid and will fall under the TSA 3-1-1 liquids rule , which mandates that any liquid, gel, cream, aerosol, or paste in a carry-on must be 3.4 ounces or less, and fit in one quart-size resealable bag (only one such bag is allowed per passenger).

Here’s a link to the TSA website advising what food can be brought with you on your Delta flight.  This applies to food you are bringing from home through security.  

Once you get through security, you can bring just about any food or beverage on the plane that you buy at the airport. The one exception is alcohol. You cannot bring open alcohol on the plane with you. You can bring a sealed bottle of alcohol purchased at the airport (such as a duty-free shop), but you are not allowed to open or consume alcohol on the plane unless it is provided by Delta.

Delta Pet Policy

Delta may not charge for your carry-on bag, but they will charge for your carry-on pet.

If you are going to bring a pet on board with you, it must be able to fit in a small, ventilated pet carrier that fits under the seat in front of you. You will also have to call Delta in advance to tell them you are bringing a pet with you and confirm that they are allowed on your flight.

Delta generally allows up to 2 pets in business/first class and up to 4 in the main cabin. Pets are accepted on a first-come, first-serve basis. So if your pet meets Delta’s pet requirements , contact  Delta Reservations  in advance to arrange to bring your pet on board.

Pets in cabin kennels will count as your one carry-on item.  In addition to the kennel, you can bring one personal item onboard the aircraft.

Here is a chart showing the pet fees Delta charges each way.   Double them for a round-trip flight.

If you do plan on bringing your pet with you, make sure you follow TSA’s pet policy and have an airline-approved Pet Carrier that conforms to Delta’s pet policy .

I have traveled with 2 dogs over the last 10 years, one was a 20 lb. Shih Tzu-Bichon (in the picture above) and another is a 12lb. Chihuahua mix. We used the Sherpa pet carrier when bringing them on a flight with us and it worked great!

Features mesh panels so your pet can breathe easily, a non-slip shoulder strap, locking zippers, and a rear storage pocket for treats and other goodies.

Approved for use on most major airlines and the small and medium sizes are included in Sherpa's exclusive Guaranteed on Board program.

Prohibited and Restricted Items

There are certain items that are considered dangerous and classified as hazardous materials. Dangerous goods are prohibited from both your carry-on and checked baggage on all flights. The rules for these items are not specific to any airline and are mandated by the Federal Aviation Administration.

Here is a list of items that are strictly prohibited on Delta flights:

Delta has no weight limit except for select flights to Asia, such as Singapore, Beijing, and Shanghai.

No. Even though Delta has a weight restriction for some destinations, they typically don’t weigh your carry-on bag. They pay more attention to the size of the carry-on rather than the weight.

Yes. If you travel to a country/airport with a duty-free store and purchase items sealed in clear plastic bags, you can travel with those items as a carry-on.

Certain types of razors are permitted in your carry-on while others are not. In general, electric and disposable razors are permitted. Safety razors, straight razors, and razor blades are not. This article will help you understand the various rules for different types of razors including electric razors, straight razors, safety razors, disposable razors, and razor blades.

There is no charge to carry a bag when you buy a Delta Basic Economy fare.  The carry-on rules are the same for all classes of service.  The main difference is with a Basic Economy ticket, you will be one of the last to board, so overhead space will be limited.

Travelling with powders, liquids, aerosols and gels

Domestic flights.

Flights within Australia are not subject to restrictions on how much powder, liquid, aerosols and gels you can carry onboard.

However, if you are travelling domestically, but departing from an international terminal (for example, Terminal 1 in Sydney or Terminal 2 in Melbourne—your boarding ticket will confirm if you are departing from an international terminal), you are subject to powder, liquid, aerosol and gel restrictions.

In particular, all aerosol containers must have a fitted cap, or locking device.

International flights

Australia restricts the quantity of liquids, aerosols, gels and certain powders you can carry onboard international flights only. These restrictions do not apply to your checked-in baggage. This applies if you are:

• leaving Australia
• transiting through Australia from another country
• travelling on the domestic leg of a flight departing from an Australian international terminal, e.g. passengers departing Sydney international airport on a flight to Melbourne.

Restrictions on liquids, aerosols and gels also apply if you are arriving on international flights.

These restrictions are strictly applied. Security screening officers have the final say if there is any doubt about what items can be carried onboard.

You are also advised to check the  dangerous goods  restrictions.

What are powders, liquids, aerosols and gels?

Powders, liquids, aerosols and gels are:

• Liquid—a substance that is liquid when at room temperature.
• Aerosol—a substance kept in a container under pressure.
• Gel—a jelly-like substance.
• Powder—fine dry particles produced by the grinding, crushing, or disintegration of a solid substance (for example, flour, sugar, ground coffee, spices, powdered milk, baby formula or cosmetics). Powders may also be presented in clumpy, grain, or compressed material forms. Note: Inorganic powder is a powder not consisting of, or derived from, living matter.

Quantity restrictions

• There is no limit on organic powders, such as food and powdered baby formula.
• There are quantity restrictions on the amount of inorganic powder that can be carried, such as salt, talcum powder and sand.
• Inorganic powders must be in containers of 350 millilitres (volume), 350 grams (weight) or less.
• The total volume of inorganic powders must not exceed 350 millilitres, 350 grams per person. 
• Passengers cannot tip powders out to fall under the 350ml threshold as the restriction is calculated on total container volume.

There are no restrictions on the number of containers of inorganic powders per person, provided the total volume of all the containers of inorganic powder is 350 millilitres or less.

At the screening point all powders in your carry-on baggage must be separately presented for screening. Unlike liquids, they do not need to be put in a re-sealable plastic bag.

Liquids, aerosols and gels

• Liquid, aerosol or gel items must be in containers of 100 millilitres (volume), 100 grams (weight) or less.
• Containers must fit into one transparent and re-sealable plastic bag like a snap-lock sandwich bag.
• The four sides of the bag's sealed area must add up to no more than 80 centimetres (e.g. 20x20 cm or 15x25 cm).
• Only one bag is allowed per passenger, with exceptions for carers who may carry the bag/s for people in their care, including children.

Containers larger than 100 millilitres or 100 grams, even if only partially-filled, containing liquids, aerosols or gels will not be allowed through the security screening point. For example, a 200 gram toothpaste tube that is half-full will not be permitted.

At the screening point all liquids, aerosols and gels in your carry-on baggage must be separately presented for screening.

Some items may not be obvious, such as snow domes or toys and souvenirs with liquid, sand or granular material inside. If you are unsure if an item will pass screening, pack it in your checked baggage.

Examples of powders
