If you’ve ever wondered, “Can You Bring Aerosol Cans on a Plane?” you’re not alone. This article will answer this question and cover TSA guidelines, liquid rules, and what you can and cannot pack in your carry-on and checked luggage. So, let’s dive in!

The Short Answer: Yes, But With Some Restrictions

Good news, folks! You can bring aerosol cans on a plane, but there are some rules you need to follow. The main thing to remember is that aerosol cans, like hair spray, dry shampoo, and deodorant, must comply with the TSA’s 3-1-1 rule for carry-on bags. The 3-1-1 liquids rule states passengers can bring 3.4-ounce (100 ml) containers of liquids, gels, and aerosols in their carry-on baggage. These containers must fit in a clear, quart-sized, resealable plastic bag.

However, not all types of aerosol cans are allowed. For example, flammable aerosols such as spray paint and pepper spray are prohibited in carry-on and checked baggage.
