Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

Flew steerage class. Short on leg room unless you pay more. No window unless you pay more. Etc. United is trying to squeeze every cent from you. It doesn’t make for any loyalty.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Outstanding service, great food, friendly & efficient crew, safe & comfortable flight

Staff were not attentive, wifi did not work, cut my head in the bathroom due to the position of the soap on the sink, had blood running down my face, told staff, they had no expression no sympathy, didn't even say "sorry", they said "oh we will have a look at that" about 10 mins later the purser brought me a bandaid, still no sorry.... Shocking

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Dinner was good, but the breakfast served in the morning was horrible.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

Somone switched seats to sit near friend causing us to be disconnected (3) business class. Very disappointed. Staff did nothing.

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

1st class seats NOT REALLY 1st class or business class but like premier economy. Should be listed as such or named something else. I have flown 1st class with other airlines and they are nothing like it at all.

The flight from Dallas to madrid was delayed for 2 to 3 hours, the flight back from Dallas to Sacramento was fine , but there were 5 gate changes within the span of 2 hours, last one was in a differny terminal. Flight and crew was okay

I was downgraded from business class to economy class with no compensation. American Airlines is absolutely the worst airline for international travel. They treat their business class customers like dogs.

OK, except for a cabin attendant's lack of attention.

efficient. on time. cabin crew were very professional and very nice to deal with. would definately fly BA again.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.
