Everything was great! This was my first time flying Alaska Air and I could not have had a better trip! Everything ran according to schedule, I was comfortable during the flight, slept the entire time, staff was great!

The woman making announcements did not specifically announce the duration of the flight as we were departing. I was able to figure it out on the map option on the screen, but I would've liked to hear it verbally. Only suggestion I would have is an announcement on the plane for which baggage claim belt our luggage would come out of. I may not have heard it though, if there was an announcement. It was not difficult at all to figure out once I was in the baggage claim area, however if this was known while we were still on the flight, I prefer to know this info!

Flew Alaska air - Plenty of leg room and much more than any qantas domestic flight! Empty flight and very short.

Flight was delayed. Inflight entertaining streaming system was not working. Too many people insist on not checking their luggage under, so we almost didn’t have space for our carry on by the time we were allowed to board.

Alaska changed my seat twice, and didn’t let me pick a seat before or at check-in

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.
