Washington Dulles International Airport

Washington Dulles International Airport (KIAD) sits 26 miles west of downtown Washington, DC, in Loudoun County, Virginia. Commercial service is dominant — KIAD is a major United hub and the principal international gateway to the DC metro — and the field handles a meaningful flow of business aviation alongside it. For the DC metro, KIAD competes with KDCA (Reagan National, 4 miles south of downtown), KBWI (Baltimore-Washington, 35 miles northeast), and the close-in business-aviation field KJYO (Leesburg Executive, 30 miles west of downtown) and KHEF (Manassas Regional, 30 miles southwest of downtown).

The four runways at KIAD handle every current business jet without restriction. Signature operates the principal private terminal. For international VIP arrivals into the DC metro, KIAD is typically the default — CBP on-field, full international handling infrastructure, and the choice of every major federal-government and diplomatic charter flow. The operational considerations are slot pressure during peak commercial banks, the persistent DC-area Special Air Traffic Rules (SFRA / FRZ) around the National Capital Region, and summer afternoon thunderstorms. Field elevation is 313 feet, no density-altitude concerns. Ground time to downtown DC is 30–45 minutes depending on traffic on the Dulles Toll Road and I-66; Tysons Corner is 20–30; Reston is 15–20.

Washington Dulles International Airport is the main international airport serving Washington, D.C., the capital of the United States. It is located 26 miles (42 km) west of downtown Washington, D.C., in Loudoun and Fairfax counties in Northern Virginia.
