Yes, you can take aerosols on a plane with specific restrictions. Aerosols are allowed in both carry-on and checked luggage, but they must comply with the TSA 3-1-1 liquid rule for carry-ons: containers can be no larger than 3.4 ounces (100 milliliters) and must fit inside a single, quart-sized, resealable plastic bag along with other liquids. Larger aerosol containers are allowed in checked baggage if the total quantity per passenger does not exceed 2 kilograms (70 ounces), and each container should have a cap or locking mechanism to prevent accidental release. However, certain aerosols are prohibited entirely due to their flammability or hazard potential. These banned aerosols include spray paint, cooking spray, WD-40, and aerosol laundry products. Only non-flammable and personal care aerosols like hairspray, deodorant, shampoo, and shaving cream are generally permitted. It is also recommended to check with the specific airline for any additional restrictions that might apply.
