Price was great. Paying for selecting seats and overhead storage was not nice. Nice new plane. On time flights in both directions.

I love Alaska and Horizon… even in the short flights, they always offer something… and everyone is cheerful and helpful. It was stormy weather but the flight was quite smooth… the pilots clearly moving up and down a wee bit to avoid turbulence.
