Airline Allergy Safety Guide
Flying with a food allergy is uniquely dangerous. You are in a sealed tube at 35,000 feet — recycled air circulates allergens from other passengers' snacks, you cannot leave, and medical help is limited. Know your airline's policy before you book.
Why air travel is high-risk for allergy sufferers
- • Recirculated cabin air can carry aerosolized allergen particles
- • You cannot control what other passengers bring on board
- • Emergency diversion for medical reasons takes 15-45 minutes minimum
- • Not all airlines carry epinephrine in their emergency kits
- • Tray tables and seat pockets are rarely sanitized between flights

In-Flight Emergency Protocol
If you or someone nearby has an allergic reaction at altitude, every minute counts.
- 1
Alert a flight attendant immediately — do not wait to see if symptoms worsen.
- 2
Use your epinephrine auto-injector at the first sign of anaphylaxis. Do not delay.
- 3
Flight crew have emergency medical kits including epinephrine on most international flights — ask.
- 4
Lie down with your legs elevated unless breathing is difficult; sit upright if you feel like vomiting.
- 5
The captain can request emergency landing priority or medical consultation via radio.
- 6
A second dose of epinephrine can be given after 5-15 minutes if symptoms do not improve.
- 7
After landing, go directly to the nearest emergency room even if you feel better.
