Flight was late to take off Plane broke down Had to move everyone to another plane Told we weren’t going to LGA but Newark Also told we would be taken to NY But United lied and we ended up at Newark at 2 in the morning Horrible experience. And the experience of trying to get compensation from United is just as bad. They could not care less about their passengers Never again!

Flight was late to take off Plane broke down Had to move everyone to another plane Told we weren’t going to LGA but Newark Also told we would be taken to NY But United lied and we ended up at Newark at 2 in the morning Horrible experience. And the experience of trying to get compensation from United is just as bad. They could not care less about their passengers Never again!

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It would have been better if the crew has supported my husband's reasons for needing to keep the space clear around his feet, rather than insisting that he put his knapsack in that space.

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

Fast checkin with the self serve terminal, good communication at the boarding gate.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

The Flight was good, pilot seemed very skillful. My wheel chair sister who could barely walk was allotted the second last seat in the aircraft, with great difficulty she managed to reach on her seat, as she required attendance we were given separate seat, even on request no one cared, so much so there were single passengers who were given twin seats. May not be taken as complaint but a reminder to the checkin staff to keep in mind in future the allottment of wheel chair passengers seats.

For each flight from Key West to Fort Lauderdale to Newark to Buffalo there were at least three delays at each leg of our trip. We were due to arrive home @11:37 but finally arrived @2:25 AM costing us an extra day at the car park. Seats are uncomfortable resulting in need to seek chiropractic care for backache. Upon deplaning my husband discovered someone had taken his clearly identified carryon from the overhead bin. I will not plan on flying again soon and not on United.

Uncomfortable seats, spotty WiFi, only Biscoff for snack (no one likes those).

boarding announcements werent clear/loud. Tired of those cookies. Of the 3 staff/attendants, 1 was good and the other 2 were mediocre.

They cancelled our flight two times after rebooking us for a later flight. We never got on the plane. We found another solution by driving.

Long delays to board due to mechanical issues with plane.

Flight canceled because they didn’t have enough flight attendants. No refunds or credits for future flights

Boarding was awful - no order, people cutting in line, completely chaotic Planes are very old and uncomfortable. Noticeable difference between Delta and United on same route.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

I almost missed my flight and they helped me out enormously

The flight from DFW to chs was delayed with multiple gate changes.

We liked quick boarding and on time departure. Seats were very uncomfortable.
