We are UK based and my daughter has nut allergies; our best experience of flying so far was with EasyJet. My husband booked our tickets and noted on our booking our daughter’s nut allergies. On 7/19/2023 when checking in staff noted and acknowledged my daughter’s nut allergies.
When we boarded the plane, the flight attendant was great and made an announcement at least twice for no one to eat nut products on the plane. Flight attendants were very accommodating throughout and I would very happily fly with EasyJet again with our daughter. Please let all airlines be more like EasyJet and appropriately accommodate nut allergy sufferers!
