The question of a SLI between West-East, is indeed "negotiable", Judge Silver thinks so anyway.
USAPA does appear to be bound by the terms of the TA (thank you ALPA), the very same TA that requires a JCBA between the East and the West to be ratified before the NIC can be implemented. Is that going to happen anytime soon? I think not.
As far as delay is concerned, "Team Tempe" has been the biggest "facilitator" of delay so far. Totally understandable, it's what they are paid to do and yes it also achieves the goal of most East pilots (at least the ones I work with) of blocking the NIC.
If we go into a merger with AMR, it will most likely be without an East-West JCBA, that being the case, the only seniority list's being used today and which have been used since the AWA-AAA combination, will be put on the table and a three way SLI will be negotiate and or arbitrated. The "marriage" contemplated in the TA, will have never been "consummated" and will therefore be "annulled", as if it never happened, because in fact it never did. On what basis do any of us East or West, to this day, bid for anything?, trips, schedules, vacations, bases or equipment, it's just as it has been since the "money men" put his thing together so many years ago. Two contracts, two pilots groups and one paint job. That my friends is a fact.
There is no "contract" to vote on for many reasons, take your pick on who to place the blame on, it really doesn't matter. Personally, I don't give a rats ass about being in the left seat, I passed the point of letting my ego call the shots years ago. Pay me Delta F/O rates for whats left of my so called career and I will be a happy camper. Fence me in to the seat and base I'm in today for the duration and you can have your NIC.
I also think you are wrong about there only being a "narrow band" of East pilots opposed to the NIC.
By the way, your statement that, "The West Pilots can still successfully allege claims against USAPA for not fairly representing them.", means nothing. You can "successfully" allege ANYTHING in this country, all it takes is money, a lawyer and more money! Go for it.
