Dulles Airport's history
Washington Dulles International Airport (IAD) is located in Dulles, Virginia, and serves the Washington-Baltimore metropolitan area. It is one of the busiest airports in the region and the 28th busiest airport in the United States, with more than 20 million passengers annually from 2004 to 2019.
The airport is named after John Foster Dulles, the late Secretary of State, and was formally dedicated by President John F. Kennedy and former President Dwight D. Eisenhower on November 17, 1962. The airport was designed to be a symbol of America's progress into the jet age and is known for its striking Terminal Building, which has become a landmark for travellers worldwide.
The construction of Dulles International Airport began on September 2, 1958, after the selection of the site by President Eisenhower. The building process took four years, and the airport opened in 1962 with a unique feature—the Mobile Lounges, designed by the Chrysler Corporation. These vehicles transported passengers between the Terminal Building and their aircraft, eliminating long walking distances and protecting them from the weather and jet noise.
Dulles initially struggled to attract flights and passengers due to its location out of town, but it gradually grew alongside the Virginia suburbs and the Dulles Technology Corridor. In 1969, the airport served 2.01 million passengers, and it has continued to expand and increase its traffic over the years. Today, Dulles is a hub for United Airlines and various regional operators, serving more than 60,000 passengers daily to and from over 139 destinations.
