Flight attendant could've been more nice. Only using half a coke can then throwing it away. I would've drank it all.

- There was a delay in boarding. - One of the crew wasn’t that professional when it came to reminding people to follow certain things. (We just simply did not hear the announcement!) And the reason probably was that we were the only teenagers (without adults) on that flight.

Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home.

I'm not sure why I paid Alaska Airlines, and received confirmation emails from Alaska Airlines, but whenever I went to check in for my flights Alaska Airlines couldn't do anything for me. Instead all they did was tell me to go to American Airlines if I wanted help. I gave you my money Alaska Air.. how about you help me?

The captain of the plane did a phenomenonal job communicating with the passengers on board. He provided us information on location, altitude, and let us know when to expect turbulence which I thought was great, as many do not communicate much with the passengers. Also the plane was in good conditions and was comfortable.

Ear headphone jack would not turn down, you could hear the show from three seats away and the flight attendant was rude when I asked her for some different headphone to see if it would help. She acted like I was stupid and said "well did you turn it down?" Of course I tried that. I was very taken back by how she acted.

The flight was delayed and we had to wait in a long slow line, however , once we got to desk , the agent was very nice and we had already been rebooked on an Alaska flight. The resolution was acceptable but it made for a 12 hour travel day instead of a 4 hour travel day.

The announcement speakers at Seattle gate B15 were too quiet to hear what she was saying. I paid for a seat thinking that I would have peace during my flight but that didn't happen. I had the window seat but the little girl who's mom put her in the seat threw a big temper tantrum when I wanted the seat that I had paid for. So i let her have it. Then, when I got to phoenix and picked up my one checked bag, it was damaged. The charge for every single item is ridiculous. I would much rather pay one fee and be done. I will never fly Frontier ever again. The flight to and from my destination was horrible.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
