The weather was exceptionally bad with very low visibility and lots of turbulence. I don’t know where they found this magical pilot - he managed to navigate the turbulence and land on a dime beautifully. Well done Alaska Airlines. And give that pilot a raise!!!

Landed safely. The stewardess was very nice and engaging.

My plane took off late from Wichita, and missed departure to LA in Denver by five minutes. Despite their being several of us, they didn't hold the plane. It's 7:39 before I'm guaranteed a make up flight because I'm told by customer service that united flies fewer flights during holidays periods despite being the busiest season of the year. United did nothing to make up for the night with family they have taken from me on vacation.

Our flight attendant Lei was absolutely fantastic on this flight. After having to run nearly a mile through the Denver airport to catch the connection to Helena after a delay in DSM, I was very warmly greeted by Lei. She regularly checked to see how I was doing through the flight and made sure I was well hydrated. She was a highlight of the entire trip!

Flight was delayed and no one could tell us why or for how long we would be delayed (not even on the kiosk) ... turns out it was delayed for 3 hours ... didn’t get a phone update until 1/2 hour before boarding. people were very rude about it. Turns out the plane had issues, so they had to send another one ...

Had to ask for food to eat. Primary meal were heated cookies that could have been used as rocks. Took forever for crew to get drinks and serve. The worst first class I have ever been on. Seats were like riding in a 50 year old car.

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.
