To keep food cold on a long flight, pack it in an insulated bag with ice packs. This combination is crucial for maintaining a cold temperature for several hours. Choose ice packs that comply with current TSA liquid rules to avoid having them confiscated at security. Additionally, freeze any permissible items (like sandwiches) before departure; they'll thaw gradually and stay cool longer. Always check airline policies and TSA guidelines ahead of time to ensure all items are permitted on board.
