A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

Great until we got to FRA. The next trip leg we were put in Business Class where seats had minimal padding!!!! They were awful and United Airlines needs to have their Lufthansa partner up their game or I won’t fly with them again!!

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

I almost missed my flight and they helped me out enormously

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.

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.

Typical AA - late by 90+ mn. Gate changed twice... Changed the departure time 6 times No explanation, no communication on reasons for delay I travel with AA twice a year... and it is consistently very poor.. I will continue to use AA only when i have to.

The gate got changed several times and the flight was delayed over an hour. Awful experience

American continues to decline in their customer service and its beyond disappointing.

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

Flight to Tampa was delayed taking off due to plane arriving late but no other issues
