It is legal to carry perfume aboard an aircraft. Can You Bring Perfume On A Plane? Regulations do, however, apply to the quantity and packing. The TSA’s 3-1-1 regulation states that perfume bottles must fit into a quart-sized bag and be 3.4 ounces (100 milliliters) or less. Bigger bottles ought to be brought in checked baggage. Before leaving, always be sure to verify TSA and airline regulations.
