It was delayed instead of departing at 9:20pm, we departed at 11pm… putting us in Columbus after 2am! It was awful. Had I known about the delay, I could have spent some time in the United Lounge… I was starving because I started my journey in Budapest… so I was exhausted and hungry. Plus I had to make new arrangements to be picked up at the airport in Columbus, instead of midnight it was 2:30 am after getting luggage and out of airport. Not feasible. I would have just stayed in Chicago for the night and gotten a morning flight.

It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

Flight was great. Efficient boarding. Short flight. Early arrival. Friendly flight crew. The entertainment system did not work well. Could not access it until the aircraft reached 10K feet or more. Lots of glitches.

A bit rush for transit. Food and entertainment are not available

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My flight was scheduled for about 6:05 departure. There were 11 gate changes from 4-7pm and the flight was 3 hours delayed due to operational issues. The plane taxied around the airport for about half an hour before stopping to be de-iced. It would have been nice if we were alerted of the plan to de-ice prior to the 30 minute drive around the airport. The flight attendant was friendly, which was the only redeeming thing about this flight. As a former flight attendant for United, I was extremely disappointed.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.
