What are considered the most passenger friendly airlines for people with peanut allergies?

Flying + nut allergy: Most domestic airlines = more likely to follow the following safety measures: have epi pen available; announce that there is a nut allergic traveler on board; have a nut free seating buffer around allergic passenger; no nut containing foods, near nut allergic traveler. But..Bring your own foods, pillow and blanket; have someone wipe down the tray + seat that will be used by nut allergic passenger.

No guarantees: While some airlines have "no peanut policies, " they cannot guarantee a nut, peanut or any other food allergen free flight as individual passengers can bring food on board and this may lead to an exposure and reaction. While airlines like united, jetblue, and southwest do not serve pre-packaged peanuts on their flights, passengers will bring their own. Flyer beware!
