AI-Enhanced Insights

Washington Dulles International Airport (IAD) is a major U.S. gateway located about 26 miles west of downtown Washington, D.C., in Virginia's Loudoun and Fairfax counties. Opened in 1962 and designed by famed architect Eero Saarinen, it serves as a primary East Coast hub for United Airlines and one of the largest airports in the country by land area. Its distinctive main terminal, original Mobile Lounge system, and underground Aerotrain make it architecturally unique among American airports.
