What are "CVG area" plates? CVG is in Kentucky, and so is LEX.
Does Kentucky have different license plates by county?

Yes, both kentucky and Ohio list your county on the plate so its easy to tell where within the state someone is from.
But with respect to another question raised, I would think a 9AM flight would still have more connecting pax-that is those from LEX, DAY, CMH, IND, etc who connect through CVG but don't pay the prices. A 9AM flight to MIA seems to be scheduled to allow the early AM connectors to make it.
