I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

For some unknown reason, my checked bag didn't arrive at the same time. I got to my destination about 30 minutes late (5pm) and my bag was delivered to my hotel at 2:06am.... in the past 4 flights with AA, they been delayed and I've missed connections and my bags. Poor service.

Check in for 5am flight at RDU was hampered by American check in counters being seriously understaffed , was told even supervisor called out. Took so long in line for special services check in that we missed our 5am departure even after arriving at 3:30am. Had to be rescheduled to later flight from Charlotte to St Thomas.

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

I had a positive experience on American. I'm blind and traveling with a guide dog and the flight attendants were so kind, friendly, and helpful towards us. They checked in on us during the flight and they made us feel comfortable and welcomed. There was an hour delay before depature, but overall the flight was a smooth ride. I appreciate that there were no issues on this long flight back home.

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

It was late, then the bathroom was inoperable plus it was very hot as well. Plane was very old

Overall, I had a great flight on American Airlines. The only compliant that I have is that my gate changed 30 minutes before boarding the flight. This was annoying because I had a connection in Charlotte and it's a very big airport.

Our flight was delayed 45 minutes and we missed our connection, while we were able to get a flight the following day the voucher for food did not work.
