CVG is too nice of an airport, and way to passenger convenient, not to have somebody start service there.....
And although not the mecca of nice weather, delays there seem much less than say Atlanta, NYC, ORD etc... They don't get nearly as many summertime Tstorms as Atlanta/DFW, no where near as much snow as ORD, NYC.
From a ticket counter to gate perspective, CVG is a very easy airport to navigate passenger speaking.
One real downfall of the airport is it's approximate location to downtown.. It's not remotely close, and no real transportation options besides taxi or rental car.
I'd love to see a carrier (LCC) ramp up serious service there. I know many JB pilots who would love to see a hub there someday. Cut the commute down to a drive to the airport!
Good luck CVG
