Plane was clean, new, on time, got us there 30 min early. Crew was nice. Honestly everyone who freaks out about Check bag and carry on fees is just uneducated. It’s very clear right on their website. Do your research and it still comes out cheaper than the big guys 9/10 times. But for $170/ticket all included, non-stop, round trip, you can’t get much better. Easily $100 less per ticket than the next cheapest airline which had multiple stops.

Seats slightly uncomfortable but you get what you pay for. Not bad for flights under 4 hours.

Not a single part has a positive remark

Well - this partner of westjet was terrible. The amount of re direction to get to the final terminal was absurd .. that's just my venting My real problem is that then "crew" or team that represent s the American Airlines / compass part was just useless. A hand full of people - myself included didn't get a chance to board the plane as they didn't make any announcements. Beyond disappointing. When you check in they take your cell phone "in case " well no call no txt no nothing. It was a joke the level of service No apologies or anything just a group of any tired patrons getting the worst customer experience. I'll never EVER book a flight that has anything to do with American Airlines or its partners

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.
