Meat, seafood, vegetables and other non-liquid food items are permitted in both carry-on and checked bags. If the food is packed with ice or ice packs in a cooler or other container, the ice or ice packs must be completely frozen when brought through screening.

On domestic flights in the U.S. and UK in 2026, almost all solid food items are permitted in both carry-on and checked luggage. This includes sandwiches, fruits, vegetables, baked goods, and dry snacks like nuts or crackers. However, the 3-1-1 liquids rule remains strictly enforced for "liquids, gels, and spreads." Foods that can be "spilled, spread, sprayed, or poured"—such as yogurt, peanut butter, hummus, jams, or soups—must be in containers of 3.4 ounces (100ml) or less if carried in a hand bag. One notable exception is baby food and breast milk, which are considered medically necessary and can be carried in larger quantities. Frozen foods are also allowed, but if they are packed with ice or ice packs, the packs must be completely frozen solid when passing through security; if they are slushy or melting, they will be confiscated. Fresh produce is generally allowed within the continental U.S., but travel from Hawaii or Puerto Rico to the mainland has strict restrictions to prevent the spread of invasive pests.
