🥪 Sandwiches

Screeners treat a sandwich as a solid food item and will not apply the liquids rule to it just because it contains mayonnaise, mustard, or butter. The spread is considered part of the food rather than a standalone liquid. You can carry shop-bought or homemade sandwiches freely through security.

Security screening does not restrict sandwiches anywhere in the world. The only situation where a sandwich might be an issue is arriving in a country with strict agricultural biosecurity — Australia and New Zealand, for example, require declaration of all food including meat-filled sandwiches. Eating your sandwich before landing is the simplest way to avoid a declaration conversation.

Airlines do not restrict how much food you bring on board, and gate agents are not involved in food checks. The only enforcement point is security, and sandwiches pass through without any issue. Some airlines may ask you not to consume strong-smelling food out of courtesy to other passengers, but there is no rule against bringing it.

Pack it as close to departure as practical so it stays fresh — there are no security rules that require you to prepare it a certain way. If your sandwich has a dressing or sauce container on the side (rather than already applied), keep that container under 100ml to avoid any liquids-rule question, though in practice a sandwich is never held up at security.
