If you click on the SCHEDULED DEPARTURES from ORD, they are ALL airborne. It looks as though FA is not picking up the active flight plans.
Due to an equipment failure at FlightAware last night, there’s going to be some duplicate flights (mostly airlines) for the next 18-42 hours. If you click on a flight on the scheduled departures page you should see another flight for the same ident that is flying or already flew. Sorry about the confusion, I’ll see what we can do to clean it up.
