If TTN continues to grow, this may come back. However, I don't think it's surprising that this one was going to go by the boards once they introduced service to Cincinnati.

(Yes, I know, these days, Columbus is a much bigger city. But unlike CVG, CMH was never a hub.)

One other thing about CVG - the last couple of times I had business out there, my company made me fly to Dayton (I flew out of PHL) because the fare was $300 cheaper. Since I had to rent a car, and it is only about 75 minutes from DAY to downtown Cincy, I haven't actually flown into the Cincetucky airport in a long time.
