The seat cushions were very worn so they were extremely uncomfortable.

Delayed, no updates, had a rewards number but was not working

The seats from lax to DFW was so tight that I could not move my legs . No WiFi and had to pay . Not a good selection of entertainment

AA should improve their in air internet & entertainment options. Seems unreasonable to charge $20/hr and should have some form of free connections. The entertainment options are also pretty limited, movies are outdated and the series only show 3-5 episodes.

The professionals have excellent customer service, the seats don´t have enough space.

We were upgraded to First Class and it was a great flight

Amazing I love American. I’ll never fly anyone else if I can help it.

I love American. I’ll never fly anyone else if I can help it.

Flight delay and multiple gate changes including a change near boarding time to another terminal, which in DFW is a pain. Pre-boarding delay and also a further delay on the ground after boarding. About an hour and a half total delay.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.
