You have to pay to choose a seat. You have to pay for carry-ons, regardless of size They only serve water, charge extra for a soft drink The seats are uncomfortable and very close together. You don't get an option to pay a lower price for carry-ons at time of purchase when booked through Kayak

It got me from point a to point b. That was the only positive thing about this flight.

Unidentified delays had me sitting in the airport for hours, seats were overwhelmingly uncomfortable, no in flight entertainment, the cabin crew kept the galley lights on so it was impossible to sleep on a late night trip, nickel and dimed over everything from a carry on bag to choosing my seat, no complimentary drinks or snacks, took forever to receive my checked bag

I hated that there were sudden updates of delays just moments before we were supposed to board, then delayed for a day, then cancelled. I was fortunate to be re-routed to San Francisco (I am on the way) now, through United airlines. All in all, it was a stressful inconvenience.

The flight arrives safely into Denver

We had to take a bus to the plane. The buses the shuttled us on, they packed tight and without apology. We then sat in our seats for over an hour on the tarmac without explanation or apologies or any courtesy shown at all to the woman who dared to get up to use the lavatory and was scorned by the crew. When we got to our destination. The crew did not even apologize for the hour delay in landing or even mention it.

Good 6.0

a bit better, the flight was only half full so it made the experience more enjoyable overall.

Kinda annoying they are always trying to upsell.

The food was pretty good.

They had no accommodations for our baby, and didn’t let us board first. It was an old plane with basic entertainment, TVs above the middle row and not all do them worked. It was particularly freezing on board. Some of the crew was nice but overall not very friendly or welcoming.

Customer service when my flight was delayed twice and then cancelled.

I hated that there were sudden updates of delays just moments before we were supposed to board, then delayed for a day, then cancelled. I was fortunate to be re-routed to San Francisco (I am on the way) now, through United airlines. All in all, it was a stressful inconvenience.

Seatback tv.

Stewardess berated a man for leaving his backpack on the floor in front of him rather than politely addressing the issue. She told him you know better than that and don’t ever do that again. It was totally uncalled for.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
