Being in Seattle, they're the local airlines for me, so a lot of my flights go through them. They have top to bottom great customer service - from the call centers to check in staff to flight attendants. Everything just works with them. I've had odd requests/problems here and there before, and the call center staff really try to work with you to solve the problem. And they're US based, not a call center in India.

I also never get the feeling the check in agents are just mailing it in. I've had bad experiences before with agents before (a tired AA agent once just through my suitcase on to the belt right after I told him I was checking in a firearm), but it seems Alaska cares a lot more and they're better trained (more consistent).

They also are a great community partner here and sponsor a lot of events and organizations including things like Pride celebrations.

I love Alaska as well. They have amazing customer support. I was stranded in SF some time ago because someone broke into my car and stole my stuff. I had an onward flight to NYC the next day. So I called Alaska and told them that I needed a flight back home since I can't make it to NYC. The person on the phone without hesitation re-booked me on the next flight back and even refunded the difference. No change fees and no extras. I was flying coach.

I also really like them as an Airline, and use them often to go to and from Hawai'i. Their staff is usually very kind and the planes are clean. I don't remember the seat sizes.. I am not a 'big' person so not an issue for me (at least yet)

They're like McDonalds. Not fancy but consistent in getting you there, OK service and no attitude.

At least in SJC, they are the only airline that consistently loads from both ends of the plane. I like them for that.
