Flying With a Food Allergy: How to Plan a Safer Flight

Flying with a peanut, tree nut or other food allergy takes some planning, because you can’t control what other passengers eat or what’s left on a seat. In an international survey of more than 3,200 people with peanut or tree nut allergy, about 1 in 10 reported an in-flight reaction, but several simple steps, like wiping the tray table and requesting accommodations ahead of time, were linked to lower odds of a reaction.

This guide covers what that research found, what an allergy-friendly airline like SWISS changed, and a step-by-step plan from booking to landing. For more, see our food allergy guides.

Quick answer

• Reactions happen but can be reduced: 349 reactions were reported among 3,273 survey respondents from 11 countries.
• Linked to lower odds of a reaction: requesting accommodations, wiping your tray table, avoiding airline pillows and blankets, asking for a buffer zone, and not eating airline food.
• Allergy-friendly isn’t allergen-free: airlines can’t control what other passengers bring or what’s left on seats, so plan as if traces may be present.
• Carry epinephrine on board. The TSA allows EpiPens in carry-on bags.
• Use epinephrine promptly if a severe reaction starts, and tell the crew.

What the research shows

In a 2013 study in The Journal of Allergy and Clinical Immunology: In Practice, researchers surveyed 3,273 people with peanut or tree nut allergy through food allergy organizations in 11 countries.

Passengers who did any of these had significantly lower adjusted odds of reporting a reaction:

• Requested any accommodation from the airline
• Requested a peanut- or tree nut-free meal
• Wiped their tray table
• Avoided airline pillows or blankets
• Requested a buffer zone
• Asked other passengers not to eat peanut or tree nut products
• Didn’t eat airline-provided food

The authors noted epinephrine was rarely used and that these strategies need more study. It was a self-reported survey, so it shows associations, not proof.

What airlines do and don’t promise

Policies vary by airline and change over time, so check the current policy before every trip. As one example, SWISS announced in 2014 that it was the first airline to meet the European Centre for Allergy Research Foundation’s (ECARF) criteria for allergy-friendly airlines. Its changes included:

• Lactose- and gluten-free food and drink options on all flights
• Special meals that can be ordered up to 24 hours before departure on long-haul flights
• Synthetic-filled pillows as an alternative to down in First and Business Class
• No decorative flowers or air fresheners in the cabin

Even an allergy-friendly airline lowers risk but can’t remove it, because it can’t control what other passengers bring on board. Ask your airline about its current peanut and tree nut policy, pre-boarding to clean your seat area, buffer zones and announcements.

Your flight plan, step by step

1. Before booking: read the airline’s allergy policy and contact them about your needs.
2. Talk to your allergist: get an up-to-date emergency action plan and enough epinephrine for the trip.
3. Request accommodations when you book and again at check-in.
4. Pack epinephrine and medicines in your carry-on. The TSA allows EpiPens in carry-on and checked bags; keep them with you, not in the overhead bin.
5. Bring your own safe food for the whole journey, including delays.
6. Pack wipes to clean the tray table, armrests and seat belt buckle.

On board

• Ask to pre-board so you can wipe down your seat area.
• Tell the flight crew about the allergy and where your epinephrine is.
• Use your own blanket and pillow.
• Eat only food you brought or have verified.
• Ask nearby passengers politely if they’d avoid nut snacks.

If a reaction happens

The ACAAI says epinephrine is the first-line treatment for anaphylaxis, antihistamines are not a substitute, and any delay can increase the risk of hospitalization or death. Use epinephrine as your action plan directs, alert the crew right away, and get medical care. Carry two auto-injectors, as ACAAI advises.

Frequently asked questions

Is it safe to fly with a peanut allergy?

Many people with peanut allergy fly safely with planning. In a large survey, wiping tray tables, requesting accommodations and not eating airline food were linked to lower odds of reactions.

Can I bring an EpiPen on a plane?

Yes. The TSA allows EpiPens in carry-on and checked bags. Keep them with you in the cabin.

Are any airlines peanut-free?

Some airlines don’t serve peanuts, but no airline can control what other passengers bring on board, so plan as if traces may be present. Check each airline’s current policy.

Should I eat airline food with a food allergy?

It’s safer to bring your own. In the survey, not eating airline-provided food was linked to lower odds of a reaction.

What should I do if I have a reaction on a plane?

Use epinephrine as your action plan directs, tell the crew immediately, and get medical care.
