My flight times changed 4 times since I originally booked the flight. The last time being the day of flight - a 2 hour delay. This meant instead of getting into IAH at 9:30p, I got in at 2:30a. This was very disappointing!!!

My flight times changed 4 times since I originally booked the flight. The last time being the day of flight - a 2 hour delay. This meant instead of getting into IAH at 9:30p, I got in at 2:30a. This was very disappointing!!!

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

Cleared standby and gave up my seat. Terrible policy and boarding experience

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.

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
