Flying on this airline is nothing short of a full blown circus clown show. On a recent return from my mother’s funeral, my only available choice from IND to PWM was American, which I hesitantly booked as I rarely fly them for many of the following reasons and never will again. I was booked IND-PHL-PWM totaling about six hours. The flight was cancelled due to NE weather. They rebooked me on a two stop flight IND-DFW (Yes DALLAS)-PHL-PWM, still all on the same day. After arriving in DFW, they continually delayed the DFW-PHL flight due to maintenance issues on the arriving flight. Finally it was delayed to the point that my PHL-PWM connection was no longer possible. They then rebooked me thru LGA with the short flight the NEXT DAY to PWM and offered to put me up for the night in NYC (or so I assumed). The flight DFW-LGA was then delayed so much that I asked to be put in an earlier flight with a lessor delay. Throughout this day chats with their AI assistant were useless as were subsequent chats supposedly with a real person(?). Only one customer service agent in DFW was actually helpful and appeared to care. Upon arrival at LGA post midnight, they issued me car and hotel vouchers in Trenton NEW JERSEY at a very old Howard Johnsons ONE HALF HOUR from LGA. The hotel was an $85, 1.5 rated hotel in a very sketchy area of NJ that I would have never voluntarily booked. As I prepared to catch the car back to LGA the next morning I received a text that my flight was cancelled. TWICE IN TWO DAYS. I went to LGA hoping to have AA book me on an earlier Delta flight. The full service line was at least 200 people deep, so I tried to reach a real person agent by phone. After 1/2 hours on hold I gave up and waited for my later LGA-PWM flight. It actually started boarding on-time, but only shortly after announced a maintenance hold. We were told it was nothing serious, just an adjustment to the Captains seat. Only one update was given while we waited 1.5+ hours for a “SEAT ADJUSTMENT”. Can’t forget to mention that on all of these planes the WiFi only worked on two. During that time at least three others flights in my area announced that they were overbooked and were taking volunteers before bumping people. Another flight to ORD announced a gate change and less than five minutes after announced that they were really not changing and announced for everyone to return to that gate. Can’t forget to mention that on all of these planes the WiFi only worked on two.🤡🤡

Paid for wifi but it didn't work once. Seats were incredibly cramped and passengers sitting in front was reclined the entire time and staff did nothing

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

In flight connectivity (via T-Mobile) was often not working.

Terrible. Internet/kiosk glitch prevented baggage checkin. Line at ticket co in Ter was under serviced and did not move. Agents did not call for flight but rather allowed time to pass. Then told each person as they reached the front if line that it was too late to check bags so they’d have to rebook flights. At least 15 people missed the flight as a result of this incompetence.

It was exactly what I expected, actually arriving sooner than scheduled.

Terrible, they canceled my flight due to an issue they had, couldn't fly me into the same place within 24 hrs so had to fly in 2.5 hrs away from my destination and spend even more money. The customer service was terrible (except at the airport in Charleston). Had to call to get my checked baggage fees reimbursed 2 wks later in which one customer service agent was very rude, wouldn't listen and then hung up on me. The second lady I spoke with was actually able to help me with that part thankfully. Would not recommend flying AA.

Delayed, missed connecting flight, ground crew double charged for international charges, were super rude and told me to just”deal with it” when I complained. Horrible airline, very frustrating.
