The rest of the "concessions" with PBS lie in the work rules, things like unstacking, who has control, and in our case most importantly how vacation affects bidding. Vacation bidding is one of the very few work rules that F9 has that is truly industry leading or at the very least near the top. Thus these are the areas where PBS may or may not be a concession depending on how the rules supporting it are written, but based on past experiences with Indigo we would lead to believe they would not be as good as what we currently have.
