What is the TSA 3-1-1 Rule?
Check the Transportation Security Administration's (TSA) current carry-on quantity rules and exceptions here. For security reasons, with some exceptions, TSA currently allows you to carry on containers no larger than three ounces.
Are there quantity limits for aerosols?
The DOT limit for a single aerosol can is .5 kg (18 oz.,) or 500 ml (17 fl. oz.,) per can. However, TSA's 3-1-1 rule for carry-on baggage also applies and may be more restrictive.
The limit for each individual passenger is 2 kg (70 oz.,) or 2 L (68 fl. oz.,) per passenger. This means that a passenger could carry 5 to 7 average size (10-14 oz.,) aerosol cans.
What are examples of prohibited aerosols?
You may NOT travel with: Aerosol laundry starch, Aerosol static remover, Spray paint, Spray cleaners/lubricants (ex. WD-40), Aerosol surface disinfectants, and other cleaners.
