The GAO report quotes are fascinating. With that logic they probably think the Obama care wesite is doing great. MIA cannot replace CLT as a real Southeastern hub. It could replace it's routes south of Miami, but it would not be effective as a hub for most cities north of there, from cities north of there of which the CLT hub is mostly made up of. Parker has covered this already. CLT is a much stronger hub than CVG.

For example. AVL-MIA-BOS would be really competitive with AVL-ATL-BOS.

The PHL example make more sense, but would JFK handle all the connecting service that PHL has?
