This all sounds good, but there clearly isn't any unity at the regional level. It looks like ASA/ExpressJet just might vote no, but they will pay for it with stagnation as fleet drawdown keeps pace with pilot attrition. ASA & ExpressJet pilots would turn on each other in a second if given the opportunity. SkyWest only has the illusion of a choice right now and will not likely unionize after SKYW, Inc makes an example of ASA/ExpressJet. Eagle will sadly fall over themselves for a chance to get to AA faster, but will blame PSA pilots for forcing them into that decision. You will never find anyone that admits to voting YES, yet it will magically pass. I really hope to be proven wrong on that, but I'm not holding my breath.
The last big player, Republic, has been awful for a very long time. They are at least trying to improve, but the NMB will apparently never release them so management has no reason to ever finish a new contract. Comair was executed, Endeavor caved, PSA gutlessly traded pay for aircraft, and Mesa sucks. GoJet really sucks and their existence will continue to prevent TSA's contract from being much better. Compass's arbitration system was designed to curtail leverage and ensure Compass never becomes industry-leading overall.
The only hope seems to be that the pilot shortage will solve our problems, but lets face it, new 121 pilots are mostly not making decisions based on pilot contracts. They will mostly still choose the place with the quickest path to the left seat and/or shortest time to get to a real airline. The wholly-owned regionals will use mainline flow or preferential interview programs to attract pilots despite poorer pay & working conditions. Meanwhile the independent regionals will get squeezed relentlessly until the labor groups buckle or the airlines simply fail. This has all been expertly played by mainline management and won't change until enough pilots are no longer willing to toil in the minor leagues for a chance at being called up to the majors.
