Quick Answer
✅ Yes. Solid stick deodorants are allowed in both carry-on and checked bags with no size limits.
✅ Liquid, gel, cream, roll-on, and aerosol deodorants must follow TSA’s 3-1-1 liquids rule if in carry-on (containers ≤ 3.4 oz / 100 ml in 1 quart bag). Larger sizes go only in checked bags.
Details
- Solid deodorant (stick, crystal, powder): Unlimited in carry-on or checked. Not subject to liquids rule.
- Liquid, gel, cream, paste, roll-on: Count as liquids → containers ≤ 3.4 oz (100 ml) inside quart bag if in carry-on.
- Aerosol deodorant / body spray: Allowed, but must follow 3-1-1 if in carry-on. In checked luggage, containers must have protective caps, and most airlines limit total aerosol volume to 2 L per passenger.
- Antiperspirant sprays fall under the same rule as aerosol deodorants.

Gotchas / Common Issues
- ✈️ Travel-size sprays only: Full-size aerosol cans (6–12 oz) are too big for carry-on → must go in checked.
- ✈️ Cap requirement: Aerosol cans must have a cap to prevent accidental spraying in checked baggage.
- ✈️ Strong scents: Even if allowed, strongly scented sprays can bother passengers in the cabin. Use sparingly before boarding.
- ✈️ International flights: Many airports follow the same 100 ml liquids rule, but always double-check destination country rules.
