Many holes in this theory. For one thing, separate ops is not going to be permanent, especially for a new hire. They will be left holding the bag when you leave, aside from making bankruptcy, poverty level wages in the mean time. Second, a closer look at how many retirements will happen from medical leave, sick leave, and the right seat paints a much less rosy picture. Third, look how good the "career advancement" analysis worked for the 17 year furloughed pilots of the east. Everyone knows that downsizing can easily outpace attrition, especially at US Airways, who is currently and for the foreseeable future without a consolidation partner.
I wouldn't count on all those "new soldiers" walking in lock step to fight someone else's battle only to be left paying the consequences down the road for those people's entitlement.
