Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

They only offered water for Group 6. Awful announcements from the Crew. Couldn't understand a single word. Barely came by for the trash afterwards. Man, I love water for a premium flight. Wow. Water in a cup.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

Waited on the runway for takeoff for 2.5 hours. Air traffic rerouted us. The plane didn't have enough fuel, so had to go back to the gate. Had to wait for a new pilot. Should have landed at 5:22. Didn't land until 9:10. Trash flight.

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.
