Solid food items (not liquids or gels) can be transported in either your carry-on or checked bags. Liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags and should be placed in your checked bags if possible.

Yes, you can take almost any solid food through security at London City Airport (LCY) or most other major city airports, but you must strictly follow the "Liquid, Gel, and Aerosol" (3-1-1) rule. Solid items like sandwiches, fruits, cakes, and dry snacks are perfectly fine in your carry-on. However, "liquid-adjacent" foods like hummus, jams, honey, yogurts, or thick sauces are treated as liquids and must be in containers of 100ml or less and fit into your transparent liquids bag. In 2026, London City Airport has pioneered the use of CT Scanners, which allow you to leave your liquids and electronics inside your bag; this makes carrying food much easier as you don't have to unpack your snacks for inspection. One important caveat for international travel is Customs: while you can take a ham sandwich through security, you may not be allowed to bring it into your destination country (especially the EU or the US) due to strict agricultural and livestock laws. Always aim to consume any fresh produce or meat-based snacks before you land to avoid a potential fine at the border.
