I'm not trying to be combative here, but even if the manpower planning guy was a legacy United guy, CAL is getting 19 new 737-900ERs and 6 787s this year, so the staffing is going up on that side. (at worst case neutral, but most likely a net gain)
However the legacy United side isn't getting any new aircraft. They haven't announced how many aircraft they are sending to the boneyard yet for 2012. I imagine we'll probably see that data tomorrow during the earnings report.
I imagine we'll see some 737-500s and 767-200s on the CAL side get sold or parked this year, but overall some growth on the CAL side(We'll see how much. On the UAL side, we'll probably see 1 or 2 747s parked, to produce an overall decrease, albeit minor.
