Yes. You can bring deodorant on a plane, but there are some rules set by TSA and FAA.
This post is written with reference to TSA rules for carrying deodorants on US flights. The rules may vary for other countries. So, check with relevant authorities before packing. Moreover, the TSA officer makes the final call for clearing a certain item through screening.
Rules for Brining Deodorant on a Plane
Deodorant (Aerosol, liquid, gel, cream, roll-on, & pastes)
Carry-on: You can take a maximum of 3.4 oz or 100 milliliters of liquid and/or aerosol deodorant in carry-on bags. Deodorant is subject to the liquids rule (3-1-1 rule); you can take 3.4 ounces or smaller containers that fit in 1 quart-sized, zip-top bag. TSA allows only one bag per passenger.
The release devices (button/nozzle) must be protected by caps or other suitable means to prevent accidental release on board.
Checked Bags: Deodorant (liquid and aerosol) is allowed in checked bags with some limitations. The FAA has limited medicinal and toiletry articles, including aerosols, to a maximum of 2 kg (70 ounces) or 2 L (68 fluid ounces) in checked baggage. The liquid-based deodorant must be packed in containers smaller than 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
Deodorant (Solid)
You can take solid deodorant in carry-on and checked bags without any size restrictions.
Stick Deodorant
Stick deodorant falls under the category of solid deodorant. There is no limit on how much and many stick deodorants you carry with you.
Can you bring perfume on a plane?
Yes. You can bring perfume on a plane. You can pack a maximum of 3.4oz/100ml bottles in carry-on bags and larger bottles in checked baggage.
Is there a restriction on medically prescribed deodorants?
No. You can bring deodorants or sprays larger than 3.4 ounces if it is a medication. Don’t forget to present the prescription at the screening before the X-ray to avoid unnecessary delays.
