The flights were on time and the staff were polite and nice.

Everything on a WestJet flight is extra and only the bare minimum is offered. There are no TVs in the seats and the seats themselves are small and jammed close together.

Crew overworked but pleasant and doing their best. Self check in works well with assistance

Management decisions meant assigned crew arrived after our flight supposed to depart. Needed 1 more person to service passengers. We waited a long time after serving started to get served. We did not know that food could be preordered online and served soon after takeoff. No TV screens on back of chairs...had to rent device to see movies. Have app but not able to book and get points. Wrote to WJ for help but oo response

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.
