I had a good time. However, I paid for the wifi and it was in and out the whole flight.

one staffer was frustrated (it happen); the flight was late and the pilot mentioned they'll make amend but the snacks were the same, other than that the aircraft was clean and everything went smooth, no complaints

The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

It was perfect! I've never flown with United before, but I definitely will in the future

I had a cancelled flight because of technical issues going to my destination, and a delayed flight coming home. All told it wasn’t a total bust.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

I cancelled my ticket less than 24 hours deadline but I didn’t get refunded.

Early morning flight and no food in First Class except a "salmon" box. No thank you. Was informed before take off by Captain that the plane was not serviced before we boarded in Phoenix. How does that happen? Need more frequent additions/turn over on the Entertainment. Thanks

Moved to earlier flight which unexpectedly had maintenance issues initially indicated as quick fix to ultimately plane changes. Moved back to original flight, also delayed. In all cases customer updates and communication very unclear, no updates on drivers for delays.

Flight was delayed. No urgency by American Airlines team to assist those with connecting flights. It was basically you are on your own to run through the terminals to try and make your connection. Thanks, Mary

I have never been assaulted they way I was today in Charlotte - shame on American

One of our group members was struggling to walk. In Charlotte we asked for a wheelchair and she was accompanied by Desmond. I was impressed by his patience and attention. In Boston she received the same service. I didn’t get the name of the helper but she went above and beyond in assisting us. A great AA service

Better snacks but flight and crew were amazing on this flight

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

It was the most un-special flight experience in my life.
