I'd say that according to several federal court rulings that if a majority of pilots vote in a new union AND they can get the company to negotiate a new seniority list AND the new SL can survive a DFR, then yeah, they can change it. Unless as CM says, MB has more weight since it is a federal arbitration instead of an intra-union one.

Bunch of ANDs, huh. We've been at it for 5 years now and are only through the first. I doubt we will see it repeated.
