Can you take deodorant on a plane aerosol?

TSA has determined that liquids, aerosols and gels, in limited quantities, are safe to bring aboard aircraft. So it is important to remember that all liquid, aerosol and gel items must be stored in containers 3.4 ounce or smaller.



Yes, you can take aerosol deodorant on a plane in 2026, but you must follow the TSA 3-1-1 rule for carry-on luggage. Each aerosol container must be 3.4 ounces (100 ml) or less and must fit inside your single, quart-sized clear plastic bag along with your other liquids and gels. If your aerosol is larger than 3.4 oz, it must go in your checked baggage. For checked bags, the FAA limits the total quantity of medicinal and toiletry aerosols to 2 kg or 2 liters per person, with no single container exceeding 0.5 kg or 500 ml. It is a peer-to-peer essential to ensure that any aerosol in your checked bag has a protective cap to prevent accidental discharge during flight. A high-value tip for 2026: many travelers have switched to "solid" or "stick" deodorants for their carry-ons, as these are not considered liquids and have no size restrictions, allowing you to save that precious space in your 3-1-1 bag for things like sunscreen or toothpaste.

The TSA prohibits containers with more than 3.4 ounces of liquid in carry-on luggage, so if you have a liquid or semi-liquid antiperspirant, be sure to check the quantity on the container. For example, many stick deodorants and antiperspirants come in sizes under 3.4 ounces, so it's fine to bring in your carry-on bag.

But remember that you can't bring all aerosols on planes, like pepper spray, WD-40, or any other aerosol that isn't intended to be used on the skin and is flammable. You most likely won't get into trouble by bringing them, but you will be asked to discard them at the airport.
