The TSA has concluded that liquids, aerosols, and gels are safe to transport aboard airplanes in restricted quantities. You may travel with full-size aerosol canisters of antiperspirant, hairspray, suntan lotion, shaving cream, and hair mousse by carrying them in checked luggage. The container must be sealed and labeled as directed by the manufacturer.
However, even though these items are allowed in the cabin they still need to be declared at the airport checkpoint security desk before you board your flight. You will be asked to show the officer the actual canister or bottle being transported in order to declare it properly. These items should not be packed in your carry-on baggage.
The amount of liquid permitted in a can or bottle is based on weight: 1 fluid ounce (30 ml) or less weighs less than 3.5 ounces (100 ml), so this can be carried in a small pocket or bag. Anything more than this requires a ticket.
There have been reports of cans exploding while traveling through security, so be sure to pack these in your checked baggage. If it comes in a plastic bottle, it's ok to carry in your carry-on.
TSA.gov also offers information about particular processes. Liquids are in charge. The TSA ruled that liquids, aerosols, and gels are safe to transport aboard an airplane in restricted quantities. The liquid rule restricts the total amount of liquids that each passenger may bring. The aerosol rule prohibits passengers from carrying aerosols or pressurized bottles onto a plane. The gel rule allows passengers to bring up to 3 grams of food-grade gel into the security screening checkpoint.
The most important thing is to be aware of the rules. If you have any questions about whether something will be allowed on a flight or not, please check with the airline before you travel so you know for sure.
Even if they are in a secure, tamper-evident container, we recommend carrying any liquids, gels, and aerosols that are larger than 3.4 oz (100 ml) in your checked luggage. These products should be kept in the original packaging and placed in a plastic bag or other container to prevent leakage.
Checked baggage carriers occasionally find liquids in bags of this size. In fact, some large airlines carry more liquid cargo than passengers. If you have an unclaimed bag found with liquid inside, call customer service immediately before taking anything out of the bag.
The carrier will need to know what was in the bag so they can report it lost or damaged. Also, be sure to include the name of the company that packed your bag with liquids.
If you are asked by security at the airport to open your bag, ask to speak with a supervisor first and show them the packing list. They may want to see the product themselves or test it in a laboratory.
Some products, like propane tanks, can be dangerous if not used properly.
Checked baggage is required for liquids weighing more than 3.4 oz or 100 ml that are not in a secure, tamper-evident bag.
Also include anything you have in a liquid or gel form such as sauces, salad dressings, oils, and other food items.
Anything over 0.5 liter carries a $150 fee. That's the limit for all flights within the United States and its territories. The only exceptions are passengers who are directly flying with one of our international carriers or who are traveling into one of the three most remote airports in the United States. These include Nome, Alaska; Keflavik, Iceland; and Buenos Aires/Ezeiza, Argentina.
The only other option is to check your bag and pay an additional $50 per item. However, many airlines including American, Delta, JetBlue, Southwest, and Virgin require you to leave something else in your checked bag to free up space for any extra items.
The amount of liquid allowed in your carry-on is much more flexible. Typically, the maximum size for a carry-on bag is 23 inches by 13 inches by 7.6 ounces. (60 cm by 33 cm by 20 cm).
Yes, TSA accepts appropriate amounts of medically essential liquids, gels, and aerosols for your journey; however, you must report them to TSA officials at the checkpoint for examination. You will need to provide your reason for bringing it on board.
TSA recommends that you pack your own medication to ensure an accurate reading on the x-ray machine and to help prevent drug theft. However, if you do not want others to know you are traveling, then it is acceptable to use a pre-packed medication kit provided by the airline.
If you choose to use one of these kits, make sure you only take out what's inside the packaging of the kit you are using. Do not open or remove any other items from the packaging.
You should also check with your doctor about whether your particular prescription will affect how you travel. For example, some medications can cause heart problems when taken by people who have heart problems or are at risk of having one. For more information on what types of medications are prohibited on planes, visit the TSA website.
The use of pain relievers and fever reducers while flying may affect how your body responds to turbulence and other airborne hazards. We recommend that you refrain from using these products before or during flight travel.
Standard stick deodorant is acceptable to bring on board a plane in either your checked or carry-on luggage. Deodorant in the form of a gel or spray is subject to the liquid or gel limitations and may not be transported in excess of 3.4 ounces. These restrictions don't apply to antiperspirants used for underarm odor control.
However, if you plan to travel with aerosol deodorants or fragrances, we recommend checking them as the container size is larger and they cannot be packed into your bag with the rest of your belongings.
Also, some carriers have specific requirements for products carried in the hold, so check with the carrier before traveling with aerosols.
When checking or carrying on your own baggage, make sure that you only pack items that are allowed by the airline you're flying with. For example, some carriers prohibit liquids from being carried in your bag, so be sure to check the list of prohibited items before heading to the airport.
