Washington Dulles International Airport (IATA: IAD, ICAO: KIAD) serves the greater Washington, D.C./metropolitan area. It is located 50 km from the downtown core in Northern Virginia. The airport is named after John Foster Dulles, United States Secretary of State under Dwight D. Eisenhower. It serves as a major hub for United Airlines and a focus city for JetBlue Airways.

On a typical day, 1,800 to 2,000 flights are now handled at Dulles, up from 1000 to 1200 in 2003. It remains the second busiest trans-Atlantic gateway on the Eastern Seaboard. Recently with the demise of Independence Air, JetBlue has slowly expanded its focus city operation at Dulles with six daily non-stops to Boston and New York. It also serves non-stops to Boston, Long Beach, Oakland, Ft. Lauderdale, Las Vegas, West Palm Beach, Orlando, and San Diego making JetBlue the second largest carrier at Dulles in terms of non-stop destinations. The inception of low-cost carrier Independence Air in 2004 propelled IAD from being the 24th busiest airport in the United States to 5th, and one of the top 10 busiest in the world. At its peak of 600 flights daily, Independence, combined with service from JetBlue and AirTran, briefly made Dulles the largest low-cost hub in the United States. Southwest Airlines entered the market in fall 2006 after Independence Air’s demise.
