Perhaps, but they have something most pilot groups lack - leverage. Oh and no RLA.
And I imagine most captains at any mainline are making more than the basic secretary at ALPA national.
It's because ALPA (and I suspect most unions are like this), is an organization geared to the top x%..... it's a Captain's union. One look at Pinnacle negotiations confirms this, and its backed up by the anecdotal evidence of what DALPA is doing (or not doing, more appropriately), for its junior pilots.
