The ticket price was amazing. It made the negatives acceptable. Friendly but scarce attendants. Although there was no electronic boarding pass for my phone, the printed one did contain useful information.

I was unable to find out how the $9 Club could save on baggage fees. No answer from online help. I thought baggage fee would be in line with American. But NO it was twice as expensive. Next time I will wear camping clothes and pack everything in my personal carry on. Web site is difficult to navigate.

Captain of the flight was funny and entertaining, landing down in Seattle was really smooth.

The delays were ridiculous; 1 hour delay for the first flight (Seattle to Chicago) and 3 hour delay the next one (Chicago to Seattle).

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.
