The 88 pilots in CVG want to be in CVG. The FO M88 plug in CVG would be a line holding captain in ATL. I bet very few M88 pilots leave CVG for ATL M88. CVG 73N will be popular or a MD into a category that isn't available via AE is another option.

NYC pilots enjoy the seniority afforded by being in NYC. The pains of commuting and the hassle of covering three airports isn't for the weak of heart. Look for them to go where seniority is best. ATL M88A will take many of them, but the GS options for those within a few hours of NYC will make the 320 and 717 viable options. ATL may have the junior captian by the time the dust settles on this one.
