Flight was delayed. Staff at the gate effectively and proactively communicated about the delay.

Very poor delay in dfw was really bad n long

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

Because of rescheduling, they had to put me on a flight that didn't go through Dallas

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

Couldn’t get the door on the plane to close leading to a nearly 2 hour delay. But, hey at least they didn’t cancel the flight.

Very clean and comfortable cabin. Amazing Mediterranean salad for lunch before landing. Great range of films to watch. Really quiet and easy to sleep on the flight also. The initial food was a bit weird: odd fried chicken pieces in some weird white gloop, but that would be my lack of cultural knowledge on the grub. Salad more than made up for it at the other end. Staff were super attentive and helpful. Great and easy flight

International baggage recheck process in Philadelphia was a disaster. Waited 1 hour and 45 minutes to receive our bags. Waited 15 minutes to recheck bags, flight notification boards were blank so we asked an AA representative for our connecting gate and we were directed to the wrong terminal and gate. Our connection window was over 3 hours and we made our flight by 5 minutes. We pulled away from the gate and sat on the runway for 1 1/2 hours. 1 of our 4 bags didn’t make it to Phoenix. The mobile app for lost baggage didn’t work, the AA rep had to manually fix.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional
