From what I've put together - RA is saying park 100 CRJ50s from DCI, of which Comair will contribute 15 aircraft already scheduled for lease-return in 2010. He's also saying no CRJ50s on routes longer than x miles, and a 10% reduction in CVG flying, but no reduction in CVG mainline. Comair pulling some/all flights out of JFK, and some/all flights going back to CVG. So that's what he's saying if you believe all the rumors.

Comair operates very little out of CVG compared to 3 or 10 years ago. If Delta wants to cut CVG flying without touching mainline they have the following to pick from:

Comair
Mesaba
occasionally Compass
SkyWest
ASA
Freedom
Shuttle
Chowtaco
Pinnacle

Historically, a 10% reduction in CVG meant a 10% reduction to Comair. No longer the case. But Flycrj200 is right, we'll have to wait and see.

There is also a 12% chance Comair will be recalling in 2015.
