KIAD Washington Dulles International Airport

Washington Dulles International Airport (IAD) is located in Chantilly, Virginia, on 12,000 acres of land in the suburbs of downtown Washington, DC. The Main Terminal opened in 1962 and was designed by architect Eero Saarinen. Dulles is a major hub for domestic and international air travel with a mixture of legacy and low fare carriers that provide air service throughout the world. Flights operate from midfield concourses A, B, C and D and from Z-gates connected to the Main Terminal. The Airport has invested in its infrastructure through a major capital program, which included two parking garages, a new airport traffic control tower, expanded B-gates, a new fourth runway, an AeroTrain people mover system and an expanded International Arrivals Building. The airport is connected to the region’s highway system via an Authority-operated, 16-mile Airport Access Highway dedicated to airport users. A 23-mile expansion of the region’s Metrorail system that includes a station at Dulles is under construction.

Dulles has significant capacity for future growth. With minor expansion, the current facilities could accommodate 45 million annual passengers (22.5 million enplanements). With all future facilities in the master plan constructed, the airport could accommodate 70 million annual passengers (35 million enplanements) operating out of 250 airline gates. The current four-runway configuration has a capacity of up to 600,000 aircraft operations per year. With a future fifth runway constructed, the airfield capacity could increase to 1 million aircraft operations per year
