The crew was friendly and funny.

The Westjet staff at the Sudbury airport was not exactly friendly. My flight was departing at 6am, and they ask to be there 45 mins before which would have been at 5:15am, I got there at 5:20am and the gate was closed. At 5:25am an employee came to check me in but still advised me to be 45 mins in advance next time. I was only 5 mins late and they weren't even at the gate on my arrival. The security at the airport was rude.

Quick boarding, good customer service, and friendly staff.

When I booked online it was a little unclear that I would have to pay extra to check a bag. No problem but would make a better customer experience if I had been aware of this

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.
