Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

We’ve had a year of delays with American, and this one was another flight to add to that list. It just reduced our vacation by a day! So frustrating. In-flight entertainment (TVs) weren’t working, There was no drinks service due to delivery issues.

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

2 hours delay on my flight causing me to miss my connecting flight. Cause was for maintenance. I understand maintenance is important but maintenance should be done before boarding people!

Better perks for corporate employees whom travel often and spend a lot of money with the airlines. Snacks were terrible chips crackers are ideas. Flight and crew were great comfort was fine entertainment not so great so so called status members means nothing

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

I blame kayak for my last trip to dca. Kayak cancelled my direct flight and put on a one stop flight and made lost whole day from my vacation and had not even refunded my ticket.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

Was the most uncomfortable I ever had in the air. Felt like I was trapped in the seat legs cramped and was just horrible. The flight to DSM was a lot better. Even being on a smaller plane was better. Staff are outstanding. No complaints about the people.

It was exactly as I expected, on time, smooth flight, courteous staff.
