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.

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.

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!

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

I paid for the upgraded bundle. Was worth it! Great experience round trip!

It was awful everything about it terrible I will never ever ever ride it again

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Not clean and was told I would get a great seat and it was not great at all

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.

Gate agent for Frontier in Sioux Falls was horrible. Some people shouldn't have jobs where they need to work with people. This person tried to control everything and even argued with a Sheriff's Deputy. He seemed to write the law and think he was immune to everything and could do whatever he wanted. What a miserable experience for a lot of people. He even delayed the flight just for on his own actions. The pilots made up the time lost, but why does this person have this job. Apparently nobody cares at Frontier. We do, My wife said she would never fly on Frontier again.
