Just thought I'd point out that Skywest just negotiated a pay raise, and there are no signs they'll be losing out on any of their 76-seat feed or EJet orders as a consequence.
Contrast that with Endeavor/Pinnacle, PSA, and add to that list Eagle--all ALPA represented regionals--all of which have taken huge paycuts just to maintain their existing flying (or marginally increase it).
Statistically speaking, if you are a regional airline pilot, it's becoming very difficult to argue that ALPA representation provides a substantive benefit to regional members. While correlation is not causation, I would argue that ALPA representation negatively affects regional airline pilots by placing them under the same umbrella as mainline MECs/national leadership, whose interests often run counter to the career interests of regional pilots.
Just two cents I figured I'd throw out there for discussion/consideration.
