I didn't eat or watch movies, so couldn't rate those. The crew we're pleasant and helpful, and the pilot got us there in one piece, which is the important thing. Then, I managed to leave my suitcase behind, after picking it up at baggage claim. I had just arrived at my destination and realized it was missing, and before panic set in I got a call from someone at Alaska Airlines, saying they had my bag. Excellent! I'd definitely fly Alaska again, and recommend it to others. Eileen

Comfort and quality of the airline is top notch, like its sister company Virgin.

A little hard to get onto the WiFi, but once on, it was fine. Hey ... it’s free so overall, still great

Friendly staff but

Unreclinable seat on a red eye flight is a torture. No attempt to move us on a diffferent seat when the flight wasn’t even full. Not the most mindful

On time and uneventful. That's all I really want or expected. Alaska came through in flying colors (pun intended).

On my return flight it seemed that the attendants were trying to stop anyone other than the 19 or 20 people in first class from using the forward bathroom. On my flight out, the cabin was asked to "wait at row 6" for the bathroom to be free. That seemed reasonable, even though I was in row 6, and fair to ask. However, on my return flight they seemed to expect the entire rest of the plane to use the rear bathroom. That doesn't seem right.

Very nice flight attendant and the landing was very smooth.

I’m not a fan of the waffle cookies, wish they had a couple of choices of snacks.

I finally got to Portland.

The plane did not arrive at gate, they gave us poor/invalid excuses as to why there was no plane. We moved from gate 73A to gate 82, in another terminal back to gate 73A for no explainable reason. Finally we left after having to checked in now at gate 73.....what a mess and over 2hrs late!

There was a fair amount of leg room.

Boarding could be a little frustrating because groups 3 4 5 were 1 lane and there wasn't a lot of room in the airport. Also, there wasn't a lot of time to get from one side of the airport to the other to stop at the restroom and get a real meal, since there was nothing served on the previous flight. Due to turbulence there was nothing served on the flight, which is beyond the control of the crew. They knrw ahead of time about the turbulence, perhaps they could have quickly passed out pretzels or cookie before the flight took off.

Flight was on time, smooth with efficient boarding and quick baggage retrieval.

Only one beverage service shortly after takeoff. No additional offers of drink or snack on 6 hour flight. Attendants were sitting around in rear galley. One was knitting! I told them that trash receptacle was full in restroom. The response was "I'll put on gloves and "push it down" but it was still unusable fifteen minutes later. Had to pay $7.99 to access flight map. No earbuds were offered. Attendants were invisible except for collecting trash.

I had a window priority seating, and without notifying me they change my seat to a middle seat and when I called to change it was pretty much told, no other seats available... Too bad.

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,
please send us an and someone from our team will get back to you promptly.
