DCA

The typical penalty for bringing your CCW up to the security line at Reagan National Airport?

A $3,900 fine.  But it could be up to $13,000.

Reagan National is IN Virginia.  So you can carry around the airport.  I wouldn't CCW inside, even if you don't intend to go through the line into the secure parts of the terminal.  Check your gun at the baggage counter if you are taking it with.  No holster.
