Flight cancelled due to overbooking, notification received while I was en route to the airport. Was assured I would be on the flight for the following day. Awoke next day and called airline to confirm, they stated my refund had been processed, I would not be on the flight, and there was nothing that they could do for me. I was forced to rent a car and take a completely different flight from another airport at a much higher price. Never again.

No food or snacks are given on flights even if they are overnight. Everything must be bought other than water and coffee/ tea. Other than that the crew and flight were nice.

We sat on the tarmac in Reykjavik for several hours before leaving to London. It was cramped and uncomfortable. They should not have boarded that flight if it wasn't going to takeoff.

It was not clear that the fare did not include checking a bag. For an international flight, it's hard not to check a bag. I ended up paying a lot more for the flights than I expected.

Was not aware that they did not provide a free meal or even snacks during the flight. So stop by a shop before heading onto your fight

It took hanging on a customer service line for just shy of an hour to get rebooked on the next day’s flights to Copenhagen Also they charged me $95 one-way for a single checked bag. That wasn’t clear at all when I booked my flight and will stop me from using your website again

This airline is disaster. They trielt live on the planet don’t give a &$!@ Made us buy new tickets for the following day for a type o on the ticket. They just didn’t care...

They kept me and my two year old in the plane for almost 4 hours and told us that we will take off every ten minutes, but obviously we never did. We got rebooked for the following day. They provided a small room to stay in and $7 wach for food. They treated us like a huge inconvenience. We had to pay for food, my husband had to take another day off work to come get us. This airline is shameless. We are spending more money to with a different air line next time.

Don’t give a single glass of water for free. It’s $4 if you get thirsty on an international flight. Disgusting and should be illegal. Not to mention the cabin smells like urine/fish. And for whatever reason this airline attracts a crowd that leaves a lot to be desired. There were several fights on my fight. Never again.

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.
