Carry On Bags: Yes (Less than or equal to 3.4oz/100 ml allowed)
Checked Bags: Yes
The FAA limits the total amount of restricted medicinal and toiletry articles, including aerosols, in checked baggage. The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces). See the FAA regulations for more information.
Permitted aerosol release devices (button/nozzle) must be protected by caps or other suitable means to prevent accidental release.
The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
