Scott AFB is the closest Air Base to my residence in MI and I have flown out of Scott, however, when I look on their Facebook page it seems as if there are never any flights out. Flights come from Andrews often so there should be flights out.
Your question is a good one, but unfortunately we are not in a position to address why Scott AFB may or may not be offering available space-a seats. You may want to consider posting your question to the Scott Air Force Base Terminal Facebook page at https://www.facebook.com/Scott-Passenger-Terminal-302813853094915/. Thanks!
