Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

It was soooo hot I was sweating even at altitude. I know you want people to sleep, but keeping it that hot is stupid!

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

The flight was on time and the crew were great.

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

I like the web site, prompt notifications, website checks in process, and airport check in. The flight attendants are attentive and polite. The return flight was 2 hours late and reason vine doesn't sound like an unplanned and unexpected issue (scheduled plane maintenance).

Not only was the flight delayed more than 3 hours but also there was no internet or movies on the flight. It was Flair/Spirit quality of experience at Westjet prices

It was good, flight was on time, boarding was smooth and done in zones, food was good too but there was no form of entertainment. Luggage’s were intact. So an overall good flight

The flight was delayed repeatedly, on the day of and in the days and weeks beforehand. The staff are alway fantastic.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

It was okay overall, but it was a 4 hours flight and the only thing we got was snacks, I really expected breakfast.

Horrible, flight on the way to Vegas was delayed significantly and then on my way back my second flight was cancelled

My wife and I both use canes. Although I had checked in 24 hours before the flight and noted we would be checking two roll-on bags, the machines at the check in area did not produce luggage tags, and staff were unwilling to help unless we joined the long queue, a very difficult challenge. We opted to take the bags on board and, of course, were relieved of the jells and scissors in the bags at security. On board crew were then unhelpful in hoisting the bags into the overhead bins.
