Here's a fresh, totally uninformed thought:
DOH safe harbors: something less than all of the East. Say one large hub or a collection of the small hubs(DCA, LGA, BOS, PIT).
Seriously, AWA pilots, even if you managed to grant an epiphany upon every USEast pilot that their legal position is crap, wouldn't you still have years or decades of bad feeling? Isn't there a possibility for a small concession, bordering on inconsequential, to provide great benefits in goodwill, solidarity and lack of whipsawing over decades?
It seems to me, totally from the outside, that the Nic award is at least ill-conceived because it's divergences get GREATER the lower down the list you go, insuring bad feeling for years to come. (Honestly, I'd call the benefit reaped by pilots hired post 9-11 a 'windfall' in laymen's terms)
Seriously, how many AWA pilots are going to want to flood high cost, hard commute east bases? So, give up nothing, or very little, for huge benefits in future good-will. Just put it in writing as a side agreement.
I can't even figure out how this would 'flow' if you created 'safe harbor' bases (either east only bases, or DOH bases) that are some sub-set of the east operation.
Again, best case scenario for west with the do nothing approach: you win the point and the opportunity to bid captains seats out of LGA and PIT and lose any chance for solidarity for years or decades: good deal, huh?
It just seems so silly to an outsider. And east pilots: you aren't helping your position with actions that verge on extortion.
