Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

Someone switched seats in business class so they could sit together and we were left apart (3). Very disappointing. Staff did nothing

I have always been pleased with their service. Would not change a thing

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

Did not use entertainment Food great Stewards had an attitude, not the best but below average from my other flights with AA or BA

They removed our booking without telling us. Cost us thousands to book last minute

My flight was late. We stayed in aircraft one hour 😩

I was disappointed with the quality of the food and the fact that I was not given a toiletry bag for an overnight international flight

I mentioned in advance that I am gluten free, however, they did not have any options on the plane for me. That was disappointing. Otherwise, the flight was totally fine.
