Comair has done this before (not allowed bookings for a flight prior to start of service ... strange policy, unless they aren't sure it will really operate). Presumably bookings will be allowed sometime in November, closer to the service date. However it has had at least 2 firm start of service dates now, which were missed, so maybe it won't be in November. Isn't Comair having a labour problem, perhaps that is preventing the start of any new service?
