I stand corrected, ALPA is not there to protect our jobs:
The mission of the Air Line Pilots Association is to promote and champion all aspects of aviation safety throughout all segments of the aviation community; to represent, in both specific and general respects, the collective interests of all pilots in commercial aviation; to assist in collective bargaining activities on behalf of all pilots represented by the Association; to promote the health and welfare of the members of the Association before all governmental agencies; to be a strong, forceful advocate of the airline piloting profession, through all forms of media, and with the public at large; and to be the ultimate guardian and defender of the rights and privileges of the professional pilots who are members of the Association.
So if ALPA isn't there to protect our jobs then why is DALPA send them our money?
Now if LM ever says this, then, I'll believe ALPA is truly looking at the collective interests of all pilots: "Our mission is to shrink the regional's and grow the higher paying major and legacy carriers."
But the impression you're left with is -collective interests of all pilots- means serving two opposing masters.
