Flying with Allergies
Airline food policies, epinephrine rules, and how to advocate for a safer cabin when you have a serious allergy.
Requesting a buffer zone
Many airlines will announce a "buffer zone" — asking nearby passengers not to eat allergen-containing snacks — if you call ahead or tell the gate agent about a severe allergy, though it's not a guarantee and policies vary widely by airline. Some, especially in the US and Canada, have moved away from offering peanut snacks altogether; call the airline's special-assistance line before booking to understand their specific approach.
Carrying and storing epinephrine
Auto-injectors like an EpiPen are allowed in carry-on baggage (recommended over checked, since cabin temperature swings in the hold can affect medication), generally without needing a doctor's note, though carrying one is still a good idea to avoid questions at security. Keep it easily accessible — in a seat pocket or immediate bag, not buried in an overhead bin.
Cleaning your seat and tray table
Allergen residue from a previous flight can linger on tray tables and seatback surfaces. Bringing your own sanitizing wipes to clean your immediate area before settling in is a simple, low-effort habit that many allergy-experienced travelers swear by.
Planning for a reaction in the air
Tell a flight attendant about your allergy when you board, not just at check-in — cabin crew carry basic medical kits and are trained in emergency response, but they can only act fast if they already know. If you react to something, use your auto-injector immediately rather than waiting to see if symptoms pass; you can always follow up with a doctor after landing, but epinephrine works best given early.
