I have an allergy to peanuts and tree nuts. I need to book a flight to europe and can choose between Lufthansa, KLM or British Airways.
Some airlines will offer not to serve tree nuts / peanuts as their onboard snack if they know in advance you have a nut allergy, while some are even willing to do a buffer zone.
I want to choose whichever of these airlines is going to be the most accomodating. If anyone can make recommendations, I'd appreciate it very much!
