Pros: The airlines don't allow enough room to sit comfortably. I am 6' 2" 250 lbs. My knees touch the back of the seat in front of me and there is no room side to side. Very uncomfortable.

Pros: Plane was clean

Cons: My belongings stolen

RSW
DFW
Okay 4.6

Cons: On both segments of the trip American changed my seat which I. I’d not realize until boarding. Way to late to protest. You pay for preferred seating but then get bumped to a lousy seat with no explanation. Likely because I was a single traveler and an American employee wanted my seat. Better not happen on the return flight

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.
