In my experience, they're okay. I prefer Continental. but Alaska is okay. Granted, the last time I flew on them, they actually still served food for free. Those days are gone.
No free IFE either. Bummer.
But, their crews are at least average.
Their ground staff here in ANC
is another matter. And let's not talk about their pilots.... whew... deep breaths...
Have a good trip, I am sure you won't be disappointed.
