The sense of humor of the staff was nice to ease the tension of a flight delay

I know part of the cost effectiveness is the fact you don’t serve refreshments but no complimentary water and coffee? Meh

Airfare was $28 each way

No plug ins, hard seats, and an odd 20 minute delay to get a off the plane even though we were at the gate. They said it was because of the "balance". Really?

Going back home to the US

I had 15 hours layover in Amsterdam so I got me a hotel.one hour after I got to the hotel I got a notification from Kayak app asking me to go get my bag from Schiphol. My bag was supposed to be directly shipped to PDX. I had to leave my hotel back to the airport and spend 2 hours trying to find it only to be told that it was going to PDX. I lost my $170 hotel room, over $70 for taxis and ended up spending the night on the floor at Schipol. I do not think I'll ever use Kayak again. The travel guarantee is a joke too.

No curb side check in, Waiting forever in line, feel totally taken advantage of with all the extra payments for just about everything. No tv on board or wifi. I will never Fly Frontier again. I question your lack of information relative to informing me relative to the warped extras s well as the way they inform me of same. Waited forever to get through with a problem on seat!

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

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.
