My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

Didn't like sitting on the waiting pad for 30 minutes right after departing the gate. If you're going to do that, just don't board so people can still get up and walk around in the terminal. My luggage was damaged by the baggage handlers.

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

The WiFi was horrific. I fly delta often and love their (usually reliable and free) WiFi. On this flight it was intermittent and when it did connect was extremely slow. I couldn’t get any work done while I was on the flight which was extremely frustrating. I was also in the exit row seat where there is now immediate seat in front of you, so while the leg room was nice, I couldn’t even watch the TV when the internet wasn’t working. Finally, for the last 20 mins of the flight, the announcement indicator came on the TV screens and took them over, even though no announcement was being made. Really disappointed.

The flight was way too HOT! And the plane did not have any in-flight TV entertainment.

Boarding was good. The flight was on time ( arrival was 20 minutes early). Inflight service was average ( US airlines have not mastered the skills of customer service yet). The food was mediocre. “ breakfast “ was downright awful and insulting. It was a piece of dough with mon descript filling that was supposed to be cheese omelette).

The tray table was broken and the food was terrible.

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!!

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.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

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

As previously stated the delay I experienced flying from Wichita to Chicago caused a host of issues. When I finally was able to be booked on the last remaining American flight from Chicago to Cincinnati, the gate changed four times with the last change occurring very near the scheduled boarding time. While I didn't have a problem moving from gate to gate, I did notice and make note of others that had mobility issues and had to move each time for the gate change.

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.
