United, from whom we bought this code-shared flight, mid-flight canceled our tickets for the rest of our itinerary, without explanation. After long delay they tried to re-issue the tickets, but Air Canada could not find the re-issue. It finally resolved after escalation to several layers of supervisors.

United, from whom we bought this code-shared flight, mid-flight canceled our tickets for the rest of our itinerary, without explanation. After long delay they tried to re-issue the tickets, but Air Canada could not find the re-issue. It finally resolved after escalation to several layers of supervisors.

Plane arrived an hour before departure. Plane was completely boarded and ready for push back when they decided they needed to change a tire. 1 hour delay on the plane when this could have been done before we got on the plane.

Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour

I enjoyed it, again I believe air Canada has better seating options and better drink options

It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Upset about cancel to St. John’s and no overnight accomodation

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Really delayed, no effort to support customers other than “sometimes we run late.”

The flight was excellent. Their was no service as we boarded, the flight attendants spent about 30 minutes just taking and not really caring that the cabin was about 80 degrees and did not offered any beverage to first class passengers or any passenger. The flight from DEN to ONT is not long but not under an hour, we received one drink and bag of chips if you were lucky. I was in first class…. I did leave my hat on the plane and it only took less than five minutes for a United rep to locate and bring it to me.

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!
