I had a great experience traveling back in October 2017 from New York to London with United Airlines. The cabin manager actually took one of my Epi-Pens (1 of 4) so that he had one on his person, just in case of an emergency. He made an announcement to the whole plane and even stopped the serving of nuts in first class. He also offered to find me food I could eat by checking the ingredients on his food list. Possibly most comfortable I’ve ever been on a flight! I would definitely travel with them again.
