Mediocre 2.3

this flight was cancelled after we boarded and no other flights were available until two days later - completely unacceptable for a 1-hour flight for which most people travel for a weekend, particularly when other airlines sent flights safely in the same conditions (Air Canada later that night, Porter early the next morning)

I love WestJet’s in-flight entertainment and the crew was very helpful. There was a maintenance issue that kept us on the tarmac for 2 hours and the crew kept us up to date the whole time.

I ordered a pizza. It was awful. Also, my seat was completely flat - no cushion or support - and I was so uncomfortable.

Mediocre 3.0

Every leg of our trip with Westjet was late, VERY late - to the point we missed our connection. Rough landings. Crew was subpar. Will fly another carrier next time.

The people, the timeliness, the attitudes - all were great!

The choice of snacks could be more healthy - veggie cup and hummous maybe!

Our original flight was delayed and Marika, at the Delta gate of another flight to the same city, was able to get us on the flight that was going to our city. We were so grateful to get home before the winter storm! We appreciate your staff and the help their quick, efficient manner to get us on a new 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.
