Booked with kayak. Reservation came from KIwi.com? Frontier flight was canceled for maintenance. No email notification that I was automatically rebooked onto United flight by frontier. 4 hrs spent trying to get through to frontier booking agent to find out. No way to call internation number at kiwi.com. Will NOT ever book again with kayak.

The boarding went quickly and was well organized

That the price to take a small carryon was just as expensive as taking a large suitcase, ended up having to pay and extra $80 r/t for a small bag and I just that's standard for them. There were no barf bags in any seats, believe me everyone around us was looking as the person next to me was getting sick on the landing because it was crazy rough. When we finally were able to get an attendant over she was as rude as could be, I'm sure this sick person next to me was sorry she "inconvenienced" the crew member, if they just put bags in the seats pockets like every other airline this wouldn't have been an issue. The seats were very uncomfortable with no padding and not able to tilt. The tray tables were nonfunctional, too small and did not extend to get anywhere close enough to reach you. The plane ride itself felt like we were on a old school bus on a gravel road. I had a round trip ticket with frontier and both trips were equally as bad. I will never travel with them again, Most of us weren't even sure if we were going to survive take off with out the plan breaking or something.

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.
