🧴 Solid deodorant

Nothing — screeners will let it through without any issue. Solid stick deodorant is not classified as a liquid, gel, or aerosol, so there is no size restriction and it does not need to go in your liquids bag. It is one of the few personal care items that bypasses the 100ml rule entirely.

No. Because solid deodorant is not a liquid or gel, the 100ml limit does not apply regardless of which country you are flying from. You can pack a full-size stick in your carry-on bag at airports in the US, UK, EU, or anywhere else without any concern.

It is extremely unlikely. Solid deodorant has no restricted classification and does not stand out on X-ray in a way that would raise questions. Screeners focus on liquids and gels, and a solid stick simply does not fall into those categories.

Either works, but carry-on is the more practical choice since there are zero restrictions. Packing it in your carry-on means it is accessible during long trips and you do not need to worry about checked bag delays. There is no need to place it in your clear liquids bag.
