Question: are you allowed spray deodorant on a plane?
Answer: So… you might be wondering what types of deodorant have to go in the baggies, and what types don't. Stick deodorant is fine in any size. ... Spray, Gel, Liquid, Cream, Pastes, and Roll-On deodorants need to be in containers no larger than 3.4 ounces and placed in a clear quart-sized baggie.
