I have a friend who's neice has a very severe allergy. I do not know what airline she fly but they agreed to not serve them on their flights. They also were allowed to board first and early so they could wipe down and clean everything she might touch. The one thing they did forget was the pull down over the window. Wiped the window not the pull down. she played with it and did have slight reaction but they were able to medicate her and she was fine. It might be worth it to shop for and airline that will help you out. good luck. I wish you a safe flight.
