Pack for a picnic, not a fridge raid.

Packing a good travel lunch is less about fancy gear and more about choosing food that doesn’t need to be cold, doesn’t smell, and survives being squished.

Security first: solid food is totally fine through airport screening. The annoying part is spreads and sauces — hummus, yogurt, and peanut butter get treated like liquids, so either keep them small or skip them. Same logic applies on cross-border trains. Anything runny or soup-adjacent is a bad idea for other reasons.

For the food itself, think picnic, not fridge raid. Crusty bread instead of soft sandwich bread. Hard cheese instead of sliced. Apples instead of berries. Nuts, dried fruit, cured sausage, crackers, maybe a pastry. The whole game is picking things that taste fine at room temperature. Tuna, egg salad, or anything raw and fishy? You’ll be the villain of the carriage.

As for the box itself: heavy stuff at the bottom, fragile on top, one sturdy container that opens one-handed. Throw in a wet wipe, a plastic bag for trash, and an empty water bottle to fill after security. That’s genuinely it.

Your seatmate will quietly thank you for skipping the tuna.
