This was a pleasant, short flight and the crew was friendly.

The service and food needs to improve to catch up with other international flights

Small plane, so no entertainment. Hour delay! Nobody explained wht the delay was all about.

Same problems with delays in Dallas. This was weather related and due to the incoming flight being delayed. This was the flight that was delayed due to a missing flashlight which turned out not to be missing.

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.

Only thing that I liked it that I got to my destination safely, otherwise American Airlines stinks.

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

Good communication at the gate and very nice crew in the flight

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

AA is always pretty solid. Was on time all the way around today so can’t complain!
