Can’t comment on the PBS system but the post you’re calling “garbage” also mentioned upgrades and transitions outside of seniority. I have several acquaintances at Skywest who have told me how they have been been denied a transition or granted an upgrade outside of seniority. Not sure how common that is, but based on the amount of people I know at Skywest and the number of times I’ve heard about the company working outside of seniority, I assumed it wasn’t uncommon. Maybe someone could correct me on that.
