Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

My flight was delayed twice. The first time because of “plane maintenance” and the second because the previous flight who supposedly “arrived early” took an obnoxiously long time to get off the plane. Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience. My previous flights with American haven’t had this many issues.

Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

I have a gluten allergy so did have any food

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.

I just for my TSA. So security line is short and upgraded to one group up. I do think the ground crew should learn new way of boarding - the passengers sitting in higher number seat should board first to prevent traffic jam.
