Can you take spray deodorant on a plane?

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 spray (aerosol) deodorant on a plane, but it must comply with the TSA's 3-1-1 liquids rule for carry-on bags. This means the container must be 3.4 ounces (100ml) or less and must fit inside a single quart-sized, clear, resealable plastic bag. If your spray deodorant is larger than 3.4 oz, it must be packed in your checked luggage. For checked bags, the rules are more relaxed but still have limits: the FAA allows a total of 70 ounces (2 liters) of medicinal or toiletry aerosols per person, with no single container exceeding 18 ounces (500ml). Additionally, all aerosol cans must have a protective cap or a recessed trigger to prevent accidental discharge during the flight. If you want to avoid these restrictions entirely, the best travel hack is to switch to a solid stick deodorant, which is not considered a liquid and can be carried in any size in both your carry-on and checked bags without any hassle.
