Doctor recommended airlines for people with peanut allergies?

Flying + nut allergy: Domestic airlines are more likely to honor the following for nut allergic traveler: a passenger buffer zone around w/ nut allergies, so nuts will not be served; announce that passengers do not eat nut-containing foods; have nut-free meals. Other common safety measures include the caregiver of affected passenger wipes down tray tables, bringing their own food and avoiding use of airline pillows.

Ask the airlines: It is best to ask the airlines regarding their policy for serving or allowing peanuts on flights.
