Washington Dulles International Airport (IAD) serves the Washington, D.C. area, located about 26 miles from the city of Dulles, United States. The airport sits at an elevation of 313 feet.

Dulles handles a mix of domestic and long-haul international traffic, with departures reaching across the Atlantic to Europe and into East Africa, alongside domestic connections. Arrivals similarly reflect this dual character, linking the airport to other major hubs within the United States as well as European destinations. This combination of transcontinental domestic routes and intercontinental flights to Europe and Africa points to Dulles's role as a significant gateway airport, supporting both national point-to-point travel and international connections spanning multiple continents.

Travelers using Dulles can expect a facility built for substantial long-haul operations, given its connectivity to distant international regions alongside a strong base of domestic service across the United States. The airport's position roughly 26 miles from central Washington, D.C. makes ground transportation a consideration for those planning connections, particularly given the scale of operations suggested by its wide-reaching route network across North America, Europe, and Africa.
