The six month limitation regarding seniority list integration was addressed in the Empire Pilots vs alpa. The court said it was possible to use events outside of the limitation.
The "Summary Domicile Variance" is the headcount except it's broken down by base, so the two headcounts would represent line jobs on the respective bids. It is not the same as "Active" pilots, which would include check airmen, management pilots, etc in both cases. So there was indeed a reduction in headcount from May 05 to the last bid which isn't effective till later this year. However, someone posted a part of the Nic that sounds like he used the headcount (which he called "active") after the 25 planes left in late 2005/early 2006 - we discussed that before. That would change the East headcount to ~2400, so indeed that's an increase from the "pre-merger" headcount. Remember also that in 2007 Nic was working with the original certified lists, first taking out non-flying pilots. So his "active" number could have been lower. And of course Nic wasn't looking at anything from 2011 since it didn't exist then. So basically it comes down to making sure you're comparing apples to apples. You can't compare the Nic headcount to any other headcount, seniority list, or whatever.
