Interesting. CVG does allow Delta to bring midwest places into the east coast network, but as an nearly all-RJ hub, it would'nt surprise me if the cost were high.
It just amazes me some of the city pairs they are able to pull off out of there- Appleton WI for one, and I think they even get out to Omaha and Lincon. US at PIT was not even able to support Madison, nor Omaha... Delta is even able to support some of those upper/central midwest (NW territitory) from ATL. How are they able to do support such a larger network from similar hubs while US can't? Of course ATL is a bigger hub with more O&D than CLT, but comparing DL and US in the east, DL seems to be able to stretch the network so much further than US.
