I always assumed one of PHL or CLT was going to fall. Before reading about the profitability of CLT, I expected a bit of shrinking there. It's not far from DC, which in turn isn't that far from PHL, which is damn close to NYC. Then again, PHL is a terrible airport to operate in and out of in the weather, yeah, so is LGA, but AAG shouldn't want to lessen their presence in NYC.
I do think it's easy to see that there are too many hubs too close together (one reason I was skeptical about the merger in the beginning). One would assume Parker has a plan, but we will have to wait for it.
It's amazing to me that the one base that's a bit removed from this tangle (ORD) Is the one losing a few lines.
