Worst communication. Delayed boarding for two hours without a single announcement until hour 1 had passed - on time status showing until our flight was supposed to takeoff and the crew had already walked away. No one was boarding. Disgusting part of DFW overcrowded with no AC on a 97 degree day. Then the first app update is that we’d take off in 15 mins… but again no one had boarded a full flight. No announcement in the terminal so everyone is just crowded around a disgusting place with no info for over an hour which turned into two. This was an overfill flight and a disgrace to passenger decency all while likely just trying to fix their own issue of overbooking. The worst airline at the worst airport.

I’ve been on 8 flights with American Airlines in the last 2 months and 4 have been delayed.

Mechanical delay > Crew Time out. No communication to passengers. Crew time out was positioned as a surprise (even though it must have been know at the time of boarding that the crew would time out.

I could not ask for more. Great service and experience.

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

I was able to check into my flight through the app and online but had issues getting my boarding pass once I arrived to the airport.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

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

Everything was great except for the wifi was junk. Crew was super friendly and helpful

It was fine. I didn't love the food but it was at least a real attempt at serving a meal, unlike my earlier flight from Nashville to Dallas.
