Baltimore/Washington International Thurgood Marshall Airport (Airport code BWI), often referred to simply as “BWI”, is the furthest of the three, located closer to Baltimore than it is Washington, D.C.

Washington Dulles International Airport (Airport code IAD), commonly called “Dulles”, is the second furthest airport at just fewer than 42 kilometres from the city centre.
