Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.

I have always been pleased with their service. Would not change a thing

My flight was late. We stayed in aircraft one hour 😩

The seats (upgraded exit row), were the last comfortable plane seats my wife or I have ever experienced. Too narrow to turn at all to find a sleeping position. Devoid of cushioning to the point of feeling the frame bars across both the seat and the back. It was extremely uncomfortable and neither of us slept on the red eye.

We were on flight for 7 hrs and there was no WiFi. Not really easy to use any of our electronics. Def not ideal

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

I liked that even though there was a two hour delay, I was notified WELL in advance, and could arrive at the airport later. Comfort was better than most airlines for the price. The crew was helpful and kind, taking time to respond to passengers’ questions, I noticed. The cheerfulness of the personnel made for a very pleasant vibe throughout. My experience was very positive.
