You know the flippant and easy answer is probably CVG. But I'm not so sure right now, I could see the 737 flying coming out of ATL and NYC especially with the increase in the 320 in ATL and the move of MEM 320 flying to NYC.

I don't see them closing CVG - yet. IF they close MEM and CVG at the same time, that will create a bunch of training events that they aren't really prepared for as this past year has demonstrated. This is just my opinion of course, YMMV.
