Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

Flight was late and TSA had shut down so (almost) no passengers could get to the gate. American failed to inform TSA to stay open! Needed to get back home so we had to rent a car & drive 13 hours all through the night. It was bad.

Very mediocre greeting as we boarded, and the lead flight attendant accent was almost unrecognizable. He joked around a lot, while trying to give the safety demonstration, but did not succeed. My wife’s row was completely missed for beverages and the lead flight attendant didn’t even know that our row was Main cabin and able to have beverages at no charge. We are platinum, 2,000,000 miles on American Airlines and this was not a stellar crew.

Had to go get beer myself from attendants in the back of the aircraft

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

It would have been better if I could have had my flight on time. It was delayed for 5 hours. Caused me to not be able to fulfill my promise to my granddaughters. Other than that it was a good trip.

Delayed due to no crew. On a major holiday travel day.

Was supposedly in main extra (row 10), but the seat spacing appeared to be regular economy (the head rest was blue, as well - same as economy, the seats in front of us had red head rests). Otherwise the flight was good and got in well ahead of schedule.

American was having a problem with their kiosks when I arrived which made the check-in and bag drop process unusually long. Additionally, they only had one person working check-in. Eventually, the kiosks were fixed and everything else went smoothly.

The flight got canceled last minute with no explanation or refund, I had to rebook for a different day
