Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Plane was extremely delayed, but not all of it was BA fault (some was). Worst part was lack of room - this had as much space as an Allegiant flight. I thought transatlantic usually gave you an extra inch or two, but not this one. Entertainment system sporadically worked and didn’t have great options. Overhead bins are old and tiny, not as good as aunties new planes.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

Besides having a LONG layover in Philadelphia to begin with, our flight was delayed and left late. We spent 7 hours in the Philadelphia airport after being in the air 7 hours from Portugal to Philly. It turned into a 24 hour day of travel which was exhausting. I know you can't help weather but our layover was difficult as my husband is handicapped. The staff was EXTREMELY helpful with his wheelchair tho!!

I was in a bulkhead seat and my tray table wasn't level. Eating was difficult.

Audi visual not working for a whole group of seats in first class. How does a plane leave the main hub in such poor condition? How much that we can’t see so immediately is also compromised?

main meals are horrible but then you dont fly for the food

It was good. Couldn’t Check in online and select seats
