I needed internet for critical matters and it never worked.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.

Any sort of gluten free snack option would be nice

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

It would have been better if I could have had my flight on time. It was delayed for 5 hours. Caused me to not be able to fulfill my promise to my granddaughters. Other than that it was a good trip.

11h50m total delay. Had to switch to another flight that was still a 7h30m delay.

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.

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Flight was delayed. Though I checked in with BA live chat three times, our special meals were not provided.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

Comfortable, pleasant staff, quiet, good entertainment, food, drinks. Better than American (flight back) when we were crammed in and staff sometimes indifferent.

The perfect jet stream back saved over 1 hour in the air.

The crew on this flight were excellent. They were friendly and attentive. It really made the flight more enjoyable.
