We were delayed. Crew was rude. Then we flew to another airport just to get fuel, which further delayed us. We arrived late to the connecting airport and missed our connecting flight home. Not given food vouchers. Had to pay for 1 checked bag despite flying internationally. Overall, very dissasatisfied with Alaska Airlines and I will be sure to go out of my way not to book again with Alaska.

I checked in to the flight 24 hours ahead to ensure I got an aisle seat, because I knew I’d probably be going back and forth from the bathroom because I had been feeling ill. When I got to the ticket check to board the flight, my name wasn’t found in the system, and I was turned away to go back to the front desk. So I did, and the person there was seemingly able to get me an aisle seat in the same row, just across from where I originally was. But, when I got to the row, another man was in that spot and showed me his ticket which was the same seat I’d seemingly been re-assigned! The middle seat was empty, and so I sat there for the time being, while we enquired about it. One of the flight attendants said they’d look into it, but just seemed to brush it off and never gave us a response. I was mainly annoyed about being shuffled around, getting reassigned a spot and was clear about wanting an aisle seat, and it never happened even though I chose that seat 24 hours ahead in the first place. I felt there were a few chances to make it right, but it never happened.

I would like to possibly see some better food options maybe for people who can not consume dairy. With the many different cheese platters, I was very uninterested. I had an early flight and thought I'd be able to eat something with a sort of substance. I was quite disappointed, I guess I'll have to be the annoying customer who brings chipotle on the plane next time.

The Captain of this flight did an awesome land g in Ketchikan, AK. The runway is short and this was the smoothest touchdown for a landing ever! Thank you whoever the Captain was!!!

The only part I could honestly say was I wish I booked an earlier flight to see Ketchikan from above prior to landing.

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,
