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.

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.

Two hours delay, probably one hour because they didn’t bring catering and they had to bring water in board. There a change of aircraft. But delays galore at CLT so it must be a CLT and/or AA operation issue. The 1 hr additional delays because nobody could bring 2 packs of water sooner is probably the best example of this airline operates

Our flight was repeatedly delayed for maintenance problems: scheduled for 9.30am, eventually delayed to 7pm! Very very inconvenient! AA should have provided a substitute plane much earlier.. On the other hand, Customer Service crew in Charlotte helped us to reach NY (LGA) by late afternoon. Thank you Patricia!! The actual flight was quick and very comfortable. As always a. excellent, professional crew. [no food on a a short hop).

Flight delayed and missed connection. Rescheduled flight cancelled after 6 hrs wait. Rerouted thru ORD, flight cancelled, overnight stay in ORD. Still in the air on new flight!

Very below average , plane from Dallas to Toyko was very poor designed plane. I had to sit for 13 hours next to fat man. Really bad seat and entertainment screen sucked

This flight never occurred because AA couldn’t get their act together.

Everything was great except boarding for the flight from Charlotte to Raleigh and seating from New Orleans to Charlotte.

For an over three hour long flight one pack of cookies was not enough.

Unlike other airlines, did not allow for basic economy flexibility for new COVID spike. Disappointing.
