Yes, deodorant can be taken on a plane, but the rules depend on the type of deodorant you have:
- Spray, gel, or liquid roll-on deodorants must follow the TSA 3-1-1 liquid rule for carry-on bags. This means they must be in containers of 3.4 ounces (100 milliliters) or less, and all such containers must fit into one quart-sized, clear, zip-top plastic bag.
- Solid stick deodorants are not considered liquids and can be packed freely in your carry-on or checked luggage without any restrictions.
- Roll-on deodorants are treated like liquids and must also comply with the 3-1-1 rule.
- Checked baggage allows larger quantities, with the FAA limiting the total amount of restricted aerosols to 2 kg or 2 liters per person, and each container no larger than 0.5 kg or 500 ml.
For international flights, rules may vary slightly by country, but the general principle for liquids usually remains similar. In summary, solid stick deodorants are the easiest to carry on board without restrictions, while spray, gel, and roll-on types must comply with liquid limitations in carry- ons.
