From what I've heard about the situation on the ground in AK, the divide between those pro-mandate/anti-mandate is pretty stark.
Alaska Air is also a rather...unique US airline, in that their service niche is one no other provider puts much effort into trying to take over.
So what happens in their internals, particularly with the evolving Southwest situation...it will be interesting to see if they suffer any service disruptions not due to normal issues in AK (moose on runway is bigger delay causer than most realize).
