Yes, stick deodorant (solid) can be carried in your hand luggage in the UK without being subject to the liquid restrictions that apply to sprays, gels, or roll-ons. In 2026, while many UK airports (like London City and Teesside) have upgraded to high-tech CT scanners that allow for larger liquid volumes, many others still enforce the traditional "100ml rule." Because a solid stick deodorant is classified as a solid, it does not need to be placed in your clear, plastic, quart-sized bag. You can carry a full-sized stick in your rucksack or carry-on without worry. However, if your deodorant is a gel-stick, a roll-on, or an aerosol spray, it is legally considered a "liquid or pressure-packed" item and must be 100ml or less and fit within your liquids bag. To avoid any confusion at the security terminal, choosing a solid stick is the "pro-tip" for 2026 travel, as it saves valuable space in your liquids bag for items that must be liquid, like toothpaste, sunscreen, or contact lens solution, ensuring a faster and more efficient screening process.
