The employees seemed impatient with their guests. It seemed like they were giving us orders, instead of easily assisting. Our flight was delayed waiting on a flight attendant. It was alright.

The employees seemed impatient with their guests. It seemed like they were giving us orders, instead of easily assisting. Our flight was delayed waiting on a flight attendant. It was alright.

We missed our connection flying back from the Middle Wast because we were misdirected by a United employee. We had purchased first class tickets, but had to need up taking a later flight that got us in to our destination at 1:00am after a long Internatinal flight and we had to sit in the back of the plane in cramped coach seats with little padding.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

Please stop those idiotic and unrelenting announcements, commercials and stupid credit card drivel. All together about 15 minutes of stupidness that annoys each passenger.

My flight got cancelled. Couldn’t get my luggage. It arrived at my destination ahead of me. I didn’t get my preordered meal. Had to spend the night in the airport.

food /beverage service was limited to one time which was unexpected for a flight that long. food wasn't very good.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

They did not have free WIFI and I was not okay with that!

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

The flight landed in Phoenix and taxied the runway for 15 additional minutes. I had a connecting flight I barely made it to because of the delay of the plane taxing the runway.

The flight was delay roughly 90 minutes. Once we arrived at O'Hare, we sat on the tarmac for another 90 minutes. I understand that O'Hare is under construction however they need to figure out a solution as every incoming flight I have been on has been delayed coming to a gate.

This flight 1810 on 7/30 from EWR to DFW got 4 hours delay. this round trip experience is bad, my AA flight 618 from DFW to EWR on 7/28 was redirected to PIT and totally delayed about 9 hours due to mixed of weather and AA IT outage and then on the way back delayed for 4 hours. Lucky, i changed my flight to UA on the way back. i don't like AA anymore. i will consider other airline options in the future.

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

I am very appreciative of the help provided to me by Dennis and Whitney. I had lost my phone at EWR airport and they were very kind in assisting me. This included advice on how to file a report and also helping me connect with family. The pilot was also great about keeping passengers updated on the flight progress with regular communications over the system.

My flight got switched and my prepaid bag didnt transfer over properly so I paid to check ANOTHER BAG. I was placed in a middle seat and it was just miserable. At least it was a bulkhead row so I had legroom. The flight just never seem3d to end

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

I’m impressed that we were on time in Sacramento after having a late departure in Newark and our made it. The staff was friendly and warm.

It was so bad it will be my last. Connecting flight gate agent closed the door in my face when i told her my husband is 30 seconds away (and we were running close/late because the preceding AA flight was slightly delayed. We had to be rebooked on a non-direct flight with an overnight layover in Phoenix. This is the worst experience ever and for no fault of our own. The flight we were trying to get on would not have been late if the gate agent allowed my husband to get there. It was senseless, cruel and very upsetting. I don’t understand why we were subjected to this.

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.
