I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

I didn't go from Reno to Phoenix I ended up going from Reno to Dallas to Tucson because my flight rebooked because my Amtrak was late I tried notifying you guys I also don't know what you ask me about my flight because you guys didn't book my flight

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

there are no options s for snack besides cookies would ve nice to have a salty option n

We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

We left at 1030 am pacific from LA and supposed to land at 7 pm Eastern in NY. They made a detour, stopped in Philadelphia and didn’t land till 1130 PM Eastern!!! Worst flight experience with no pilot communication with no explanation as to what was going on. Everyone was very frustrated to say the least.
