I think our energy would be *far* better spent replacing Moak and his disciples at national, and making sure our local regional reps are good guys/gals who aren't afraid to take a stand, won't take the copout of letting a fearful membership vote on concessionary contracts, and have the same interests as the majority of regional pilots who want to move on, rather than the few lifers that benefit from larger planes at the regionals.
Frankly, I don't think our interests truly conflict. Most of us want fewer outsourced jobs, higher wages at the regionals so they support the people who want to stay while not dragging down narrowbody wages at mainline, more jobs and higher pay at mainline. The only conflicts of interest that occur are when 1. Regional pilots are willing to secure mainline-type flying no matter the cost, even taking concessions to do so and 2. Mainline pilots believe that cheap feed is necessary to subsidize their higher pay (i.e., Moakism). Keep those two groups out of power at their respective carriers, and we can work together for the good of the profession. Keep them in power, and having completely separate unions won't make a lick of difference.
