The boarding was a mess as there was another document check in the small congested area after the stairs at the gate. No food is offered for Economy travelers except for a cookie and a small water bottle. No entertainment is available since it’s a short flight. But at least the seat reclined as opposed to my flight to Faro.

The boarding was a mess as there was another document check in the small congested area after the stairs at the gate. No food is offered for Economy travelers except for a cookie and a small water bottle. No entertainment is available since it’s a short flight. But at least the seat reclined as opposed to my flight to Faro.

Flight attendants need to come by a little more often to pick up trash.

Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.

The whole experience was excellent, O can say out from Miami the best airline to travel with for any European destination. Since the ground staff to the inflight crew attention was great, service on board 10 of 10. Finally the 380 is very confortable and nice to travel.

Cramped seating but standard in all smaller aircrafts today no matter what airlines. Crew very helpful, friendly & attentive so makes up for that.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

I had a mixed experience on this flight. The plane itself was comfortable, the flight was smooth, and the entertainment selection was excellent with plenty of movie options. However, the service fell short. I had an entire row to myself and fell asleep with a blanket over me. A flight attendant, Karleigh, woke me up to see if I had my seatbelt on, which felt unnecessary given the situation. Meanwhile, trash sat uncollected on the tray at the end of the row and was never picked up. During the second meal service, no one woke me up, and when I used the call button multiple times, there was no response. I eventually had to walk to the back to ask for assistance. There was also a long stretch without snacks, and when I requested something savory, I was dropped off sweet options, which wasn’t ideal. Overall, while the flight itself was comfortable, the lack of attentiveness and responsiveness from the crew made the experience disappointing.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.
