Washington Dulles International Airport (IAD) is located in Chantilly, VA on 12,000 acres of land 26 miles from 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 eleven domestic legacy and low fare carriers and 22 international carriers which provide air service throughout the world. Flights operate from midfield concourses A, B, C and D and Z-gates connected to the Main Terminal. The Airport is currently in the midst of a major construction program called D2, Dulles Development, which includes projects for expanding the Z-gates, expanding the International Arrivals Building in the Main Terminal, constructing a fifth runway, and building a new permanent Concourse beyond the present location of Concourse C and D. Dulles is in a constant state of evolution and improvement.
