It is located 26 miles (42 km) west of downtown Washington, D.C., in Loudoun and Fairfax counties in Northern Virginia.[4][5]

Opened in 1962, the airport is named after John Foster Dulles, an influential secretary of state during the Cold War who briefly represented New York in the United States Senate.[6][7] Operated by the Metropolitan Washington Airports Authority, Dulles occupies 13,000 acres (20.3 sq mi; 52.6 km2),[2][8] straddling the Loudoun–Fairfax line.[9] IAD ranks fourth in the US in terms of land area, after Denver International Airport, Dallas Fort Worth International Airport, and Southwest Florida International Airport. Most of the airport is in the unincorporated community of Dulles in Loudoun County, with a small portion in the unincorporated community of Chantilly in Fairfax County. The Town of Herndon is the closest municipality to the airport.
