I live in DC and by far this is the worst airport from a ground and baggage service perspective. In the last 3 months totaling 4 flights, landing in DCA I experienced waiting for ground crew to park the plane every time. On one flight we sat on the tarmac 30 min due to our gate being occupied by a empty plane that was not departing for sometime. Poor management and lack of sense of urgency seems to be an issue with this airport
