Washington Dulles International Airport
Washington Dulles International Airport


Washington Dulles International Airport (IAD) is a bustling airport in Dulles, Va., just 26 miles from Washington, D.C.’s downtown core. More than 23 million passengers travel through IAD, making it the 28th busiest airport in the nation. Established in 1962, the 11,830-acre airport has seen several rounds of renovations and improvement projects over the decades. Its most recent $3.4 billion D2 Dulles Development capital construction program expanded some concourses, built two new parking garages and constructed a new permanent Gate Z.


Five runways handles IAD’s considerable daily traffic. The airport’s Main Terminal building is 1.1 million square feet that leads to five concourses: Concourses A, B, C, D and Z. The concourses offer a total of 135 gates. Gates are accessed via the airport’s new AeroTrains, its 19 Mobile Lounges or its 30 Plane Mates. A new 1,000-foot walkway enables travelers to access Concourse B via moving sidewalks in addition to existing Mobile Lounges.

International flights use the airport’s International Arrivals Building or a secured space in Concourse C to process international travelers. The International Arrivals Building houses U.S. Customs, Immigration, and Agricultural offices.

In addition to passenger travel, IAD sees a fair amount of cargo and freight activity at its seven air cargo buildings. The buildings provide 540,000 square feet of freight processing space while the airport’s two large fixed base operators provide needed services to most of IAD’s airlines.

Passenger Services

To help guide travelers to various parts of the airport, yellow-clad student volunteers are available throughout IAD. The volunteer high school and college students are recognizable for their bright yellow shirts and large “May I Help You?” buttons.

Passengers have plenty of options to while away the time between or before flights at any of the airport’s 100-plus shops and restaurants. Concourse B alone has 13,000 square feet of retail space. Combined, all of IAD’s shops, restaurants, and coffee bars consume more than 50,000 square feet of space, giving travelers a variety of choices and locations.

Additional entertainment is found in the airport’s extensive public arts program, including a performing arts program that offers live singing and dancing. IAD also houses a number of temporary and rotating art exhibits throughout its terminal and in the Gateway Gallery near Concourse C. Permanent public art installations include a human-powered airplane suspended above the airport’s C Gates and four immense lenses positioned below the skylights of the International Arrivals Building.

For travelers who want a few minutes of peaceful reflection or prayer, the airport houses a 24-hour interfaith chapel on Concourse A. Catholic, Protestant, Jewish, and Muslim services are held there throughout the week.

A variety of services are available at the airport for military personnel and their families at the USO lounge in the Main Terminal across from the No. 12 baggage claim area. The lounge provides a kitchen and many of the comforts of home.
