🧴 Deodorant

If the aerosol can is over 100ml, it will be confiscated at the checkpoint. Aerosol deodorants — including spray deodorants — are classified as both a liquid and an aerosol, so they must comply with the 100ml per container rule and fit in your clear quart-sized liquids bag. A stick deodorant of any size passes through with no restrictions at all.

Yes. Australia and New Zealand impose stricter aerosol rules for checked baggage — each aerosol container must be no more than 500ml, and the total across all aerosol containers in your checked bag must not exceed 2 kilograms. This is more restrictive than the US, where aerosol deodorants in checked baggage face no specific quantity limit for personal use. If you are flying to or from Australia or New Zealand, check that your checked bag does not exceed these totals.

Screeners can usually identify the type by looking at the container on the X-ray or in person. A solid stick goes through without any scrutiny. A roll-on or spray must be in your liquids bag and within the 100ml limit — if it is not, the screener will pull it out of your bag. Switching to a solid stick before travel eliminates any checkpoint friction entirely.

Use a solid stick deodorant — it is the only format with no size restriction and no requirement to be in your liquids bag. If you prefer roll-on or spray, make sure the container is 100ml or under and include it in your clear liquids bag before you reach the checkpoint. Do not pack a large spray can and expect to argue your case — it will be confiscated.
