I flew with my food allergic teen (Peanut, Tree-Nut, Sunflower, Sesame) round trip Trenton, NJ – Orlando, Florida last week (August 2017). On both flights, the Frontier gate attendants and flight crews were respectful and readily accommodating.
The ticket agent reminded me that they couldn’t guarantee than passengers refrain from bringing or eating nuts, which I acknowledged. We were allowed to pre-board to wipe down our seats, and the flight attendants made an in-flight announcements requesting passengers not eat nuts during flight due to the presence of a food-allergic passenger.
On the outbound flight, the flight attendant double checked with me how many rows we needed as a nut-free buffer (I said three). In spite of this, on the outbound flight two passengers behind us began to eat peanut butter crackers immediately after take-off. My daughter detected the smell in seconds. Fortunately, my daughter is not airborne anaphylactic.
I asked the passengers to please not eat their crackers, and offered to buy them a nut-free snack from the cart. One passenger was gracious, the other not so much – but they put their crackers away. It’s unfortunate that I have to pay for life-saving courtesy, but my experience is that it smoothes any ruffled feathers to offer. In short we had great flights and we are grateful!
