It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

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

The plane was very warm and the crew turned on the lights for the entire snack service.
