British Airways does not allow for check-in through app or website. There is a message that passports need to be scanned, but no way to do it. Check-in was unavailable at airport kiosks, so we had to do it in person at the desk. Not a huge deal, but allow plenty of time! Also a bit stressful if you want to choose/change/buy a seat as it is very last minute.

Dont get to Prague airport too early if you are checking a bag because they dont even tell you where you can go to check you bag until just a little before the flight. We sat and waited for no reason

The signs on posts in the Prague airport aren't tall enough, so if there are people in queue who happen to be in front of the signs, they're easy to miss. These signs are important to know which line one must use for ticketing: ticketing, bag drop, or level of passenger.

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.

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.

British Airays fails to enforce its own guidelines regarding carry on size limits. There were MANY passengers with full suitcases stuffing them into the overhead compartments leaving no space for others, like me, who adhere to the posted sizes. I had to put my carryone bag into my foot space, in additon to my carryon personal item, leaving me cramped for a seven hour flight. I was in physical pain, and I attribute this entirely to staff unwilling to enforce limits. The infotainment system was horrible. the touchscreens did dot work correctly, and there was no information on system operation. I am 77 years old, and a lifelong movie-goer. I recognized ONE movie (and not much better TV shows). It seems that BA saves royalty money by limiting its move and TV selection to absolute rubbish. The FlightAware program is the worst informationsystm I have ever seen, it is completely worthless. I pay attention to the safety briefings...in the event of an emergency, one is supposed to assume the "brace" position, except the seats are so close together, front to back, that it is not possible to assume the position without striking the seat in front of you. at age 77, and a lifelong traveler, this is the worst flight experience I have ever had, and I will never fly British Airways again

Overall ok. Best part has always been the sundae dessert.

I’ve never been on a trans-Atlantic (or Pacific) flight where the seats don’t recline—not even a little. I asked my seat mate when BA starting doing this and he said “Oh, a few years ago.” I couldn’t sleep, with my head falling forward waking me continuously, and came off the plane incredibly stiff. I booked a Premium Economy seat to get a more comfortable seat, which was worse than most basic Economy seats I’ve ever booked.
