Question: are you allowed to take aerosol deodorant on a plane?
Answer: TSA has determined that liquids, aerosols and gels, in limited quantities, are safe to bring aboard aircraft. ... If you want to travel with your full-size aerosol containers of antiperspirant, hairspray, suntan lotion, shaving cream, and hair mousse, you can do so by packing them in your checked baggage.
