I didn't end up taking this flight. I got up at 4am for a flight that was supposed to board at 6am - at 5:55am you delayed the flight to 10am. The airport is under construction so I switched to a later flight as I wasn't going to sit in the airport for 4 hours. They said the delay was due to the crew needing rest from a flight coming in late the night before - if that was the case then I think you should have delayed the flight much sooner so that passengers wouldn't get up so early and get to the airport to sit and wait.

The flight attendants and the service is getting worse by the day.

Other than nearly three hour delay for maintenance issues, everything went smooth

why would I bother with this airline and pick seats when I am asked to move for a weight imbalance

Overall good. The pilots and flight attendants are excellent! The equipment was the issue on my First flight as they had to wait for a part to be installed. So the take off was at least 30 minutes later.

For my arriving destination, we were delayed multiple times to the point that we arrived 6 hours after we were originally scheduled. On my flight home, they overbooked and involuntarily removed passengers (including me) from the plane. It was not a good experience.

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

Horrible. Got delayed many hours because their pilot wasn't trained for night landing at the airport and a rain delay made it a night landing. We have to wait hours for a qualified crew. They give us 12 dollar meal vouchers but most everything in the airport was closed and definitely more expensive than the vouchers.

I am an AA flyer for a very long time... AA has yet to disappoint.

Everything was good. Flight was very full so crew was busy. After we boarded and plane pulled away from the gate, we were delayed about 40 minutes- sitting on the runway - due to weather en route or at the destination. While weather is not the fault of the airline- it’s terrible to sit on a plane and not moving.
