Yes, you can bring chapstick on a plane, and it is generally not counted as a liquid under the TSA 3-1-1 rule. Solid sticks of lip balm, lipstick, and solid deodorant are considered solids by security agencies like the TSA in the US and similar authorities in the UK and EU. You can keep them in your handbag or carry-on without needing to place them in a clear, quart-sized plastic liquids bag. However, there is a catch: if your lip product is a liquid lip gloss, a gel, or a cream/paste in a jar, it must follow the standard rules (3.4 oz or less and placed in the clear bag). In 2026, with the rollout of new CT scanners at many airports, some security officers are less strict about small items, but the official rule still distinguishes between "solid" sticks and "semi-solid" gels. Because cabin air is famously dry, carrying a standard solid chapstick is actually a travel "pro-tip" to prevent uncomfortable chapped lips during long-haul flights.
