If you're CVG 50 based and you switch to the 70/90, you'll see a lot more of JFK and LGA. You'll have trips that won't see CVG except first and last legs. I'd say only about half of the trips are CVG trips. The rough trip breakdown on the 70/90 are:
40% CVG out/backs
30% JFK o/b
20% LGA o/b
10% ATL o/b
These are just my estimates. But most trips seem to be loyal to just 1 hub. For example the last few trips I've done this month were:
CVG-MSP-ATL-CMH-ATL-IND-ATL-CAK-CVG
and:
CVG-BOS-JFK-BOS-JFK-BUF-JFK-DTW-CVG
and:
CVG-LGA-DAB-LGA-DAB-LGA-JAX-CVG
