The seats on Frontier are not comfortable at all. You can't recline. Also did not like the fact that you had to pay for both carryon and checked bags.

NOTHING!!!!!!

I booked a flight with them for the Thanksgiving holiday.... I was supposed to travel Wednesday 22 - Saturday to STLand back... I was IMMEDIATELY shocked by only being able to carry 1 personal item... When I found out exactly how small 45 centimeters was...I tried to cancel the trip & be refunded within 5-6 hours.... They told me to fill out a form & return it to them... THEY WERE SUPPOSED TO GET BACK TO ME WITHIN HOURS TO NOTIFY OF THE REFUND AMOUNT & NOT...I REPEAT NOT ACTUALLY CANCEL THE TRIP UNLESS I AGREED TO THE REFUND AMOUNT... I never heard anything from them! I just assumed it was just taking forever for them to approve my refund... Therefore...assuming that the flight was still booked...SINCE I never APPROVED ANY REFUND... I visited kiwi.com several times before the the trip & there was ABSOLUTELY NOTHING informing me of any trip cancellation... I went to the airport... Wasn’t able to board... Talked to kiwi.on the phone... Didn’t find out the trip was canceled until after the boarding was closed for that flight.

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.
