They said there is nothing they can do and tell me to get back to my seat. The whole fight I was sick. It was a horrible no crews member were asked me how I felt. No crews member checked me if I were ok. I had fever and so sick. There were late. I never have any bad fight like this forever.

Cons: Seats are REALLY uncomfortable as they're thin and don't recline, no USB plugs in plane or Wifi available. Lots of turbulence on this flight which sucked, but that's out of the airline's hands I suppose. The trip from Seattle to Denver was even worse. Bag drop took over an hour, and the plan wasn't ready when it was supposed to be. Took forever, which sucked on a red eye.

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. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
