Any way to reroute your final flight destination from Dulles Airport to Richmond Airport? Or see how much a separate flight would be from Dulles to Richmond. It is not convenient to get to Richmond by train, though do-able. Note there is a transfer at Metro Center, so IAD metro station silver line to Metro Center, transfer to red line to Union Station, then Amtrak to Richmond. Feels more like 4 hours-ish to me.
