Had to sit on the tarmac for a half hour...not the airlines fault. Alaska held my connecting flight to accommodate 5 of us!

Feb 1, 2020

Very turbulent. Not airline's fault.

Jan 24, 2020

They assigned me a window seat at the back of the plane, near the bathroom. I complained and after time they moved me to a much better seat, near the front of the plane.
