Could it be due to this, there was a similar recent activity which did include the airport I think?:

The aircraft you are using is due to fly me to JFK tomorrow (20th) and is already showing an unknown delay, so I'm interested to hear how things progress for you. I currently cannot see any next scheduled hops for you or the aircraft on from KWI.
Good luck!
