I did not like the fact that I was padded down not once but twice at the age of 69 almost 70. Really did not know I was a threat to the airlines. I'm staying with my daughter at Ft.Bragg.

When I booked the return leg of my trip Kayak displayed a price of under $200 from Frontier but when redirected to Frontier’s site the time listed on kayak was only available for an additional $450+. I had to book a later flight resulting in a 14 hour layover.

The flight was good. Takeoff and landing were great. Service in flight great.

The online safety show didn’t work. They started it several times, then did it in Edson. The overhead reading lights flashed on and off periodically making me a bit concerned about the electricals. Our main piece of luggage was sent on a different flight. It took us over an hour to locate that had happened. We waited at the distribution point. We got one Piecebut not the other. After all we’re taken from the belt we went in search and found it.

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.
