Comair's commuter clause requires you to have two flights that arrive at least 30 minutes prior to your report time.

For kicks I just checked travelnet - the first two flights from CVG to JFnK arrive at 1:32 and 4:13pm. In order to use the commuter clause, the earliest report you can have is 4:43pm for a 5:43pm departure. Otherwise it's a hotel in JFnK.

Good luck hoping Comair will build "commutable trips" for the 500 or so CVG commuters...
