Okay 4.6

The seats were clean; the cabin looked very nice. The plane got me from point A to B safely. smoothest Lansing ever!

Flight was delayed 2.5 hours. No communication from the cockpit, 2 out of the 4 flight attendants we really crabby. Undersea storage was unusually small. I’m 5’8” and my knees were pressed against the seat in front of me and the seats are hard. My legs were numb for part of the trip.

Excellent Crew - I flew standby, so have great gate agents and flight attendants makes all the difference when you’re hoping for a seat. In flight they are professional and personable and keep you up to date on what you need to know! Plus, I’m always happy when my flights have USB ports so I’m fully charged when I deplane.

I always want more leg room or a little more room under the seat in front of me. But I didn’t upgrade for a roomier seat and there was more than enough overhead space, so truly can’t complain about it!

Friendly and calm professionals in the "assistance" line. The ticket kiosk did not recognize my confirmation number or name so I was instructed to wait in the assistance line and I was furious- swore I'd never fly with Alaska again- but then the ticket agent was fantastic, calm and helpful and helped put me in a better mood. Overall flight was great. Felt safe, hardly any turbulence and friendly flight staff. Flight was on time. No delays.

No screens on the back of seats with free entertainment. I don't like paying extra for entertainment. I wish you had good vegan food options.

Flight had open seats in fact I had a whole row to myself. Plane was clean and new, it even had plug-ins for every seat for charging devices. WiFi was was overpriced but they had movies you could rent and some free. Flights were on time.

The crew was extremely pleasant and genuinely accommodating. (and USB ports on every seat?!

No cash-handling for meals and services... (but that's my fault for assuming it would be cash only).

I loved the free chat and free entertainment! It made such a long flight go so much better and goodbyes and travel easier knowing that I could communicate on the go! For someone with social anxiety, being able to talk to loved ones when I was going through things was the best experience ever! Thank you so much!

Alaska Airlines had a very comfortable flight with great attendants and power to charge all your devices.

The wifi service was really poor. I paid 49.99 for Gogo and I got the service of less than a 56.k modem.

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.
