I say if you live in Cincy go with comair. We are overstaffed it seems in JFK and a lot of guys are timing it so that once they are off IOE they go straight back to CVG. On the other hand JFK is a much more fun base as far as crews go. (my opinion) And you can get senority a lot quicker. However i hear the commute isnt so easy. Just my 2 cents.
