The staff was nice. I appreciated that I was able to take an earlier flight, even though it was last minute. The boarding process felt rather chaotic.

The staff was nice. I appreciated that I was able to take an earlier flight, even though it was last minute. The boarding process felt rather chaotic.

Overall a good experience, however Wifi was not working on the flight.

For a 4 1/2 hour international flight all we got was 1 small pack of cookies and a drink. You had to watch movies on your own devise.

Airlines should be prohibited from using the seats they get away with.

My flight got delayed a total of five times. And the boarding gate changed four times. most of the time the platform was not up-to-date with the changes taking place. The most discouraging part of the entire trip by far.

Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

The crew was very kind, but no in-flight entertainment monitors and a 2 hour and 30 minute delay was extremely frustrating.
