All the stewardess' and pilots were very friendly and even noticed that they were friendly to one another. Planes were clean, seats were comfortable. It was my first time flying at 54 years old and the stewardess' checked with me several times to see how I was doing and even the pilots spoke to me about my fear of flying prior to take off. All in all Alaska is great to take care of their passengers the way they did. They seemed to go the extra mile on both my flights.

Teeny little plane but easy (early i think!) boarding process and nice flight attendant.

We were in quite a long line to take off and when we arrived in bmore there was no one to manage the jet bridge and we sat for a little while. Seems like these issues should be easy to solve - you know when the plane is arriving for over an hour!

PLane ride was very pleasant other than having to sit on tarmac for 35 minutes before flight because of flight back up.

Sitting on the tarmac for almost 40 minutes due to busy traffic. There were 17 planes in front of us!!! I just don’t understand how that happens. And if they know that In advance why can’t they figure out system to let people stay at gate as long as possible. There must be way to develop a queue system that doesn’t force people to board unnecessarily. Or at least stay at gate so people can use restroom. Frustrating!!!

The Delta service desk was great! We wanted to get an earlier flight home and the Delta Rep got us on standby quickly and with a smile.

Some chaos getting on the flight. The area they have set up for the different sections to wait before getting called weren't marked very well so everyone was bunched up and confused. Once they started calling the sections it was fine. Not sure why they even had the marked areas.

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,
