Lowest fare

Online checkin failed, airport kiosk couldn't handle how names are written on Japanese passports (it's English) and had to wait 2 hours on the line to check in because they were down to 1 agent toward the end. Made it to the gate just as boarding started. Very limited entertainment options for modern day airlines. Uncomfortable seating.

I like that they are Canadian

I don't like how unhelpful they are, their food, their staff, the way they treat clients etc. Seriously my least favourite company to fly with. I'd rather pay extra and fly WestJet anyday!

Okay 5.6

They have good entertainment system and library

The plane delayed for almost 90m due to a mechanical issue. Of course, we missed our connection in Vancouver. Upon arriving in Vancouver, there was no help at all or guidance. Customer support desk was manned by one agent even in the presence of long queues.

Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in 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.

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.
