The Terminal was originally built as a compact two-level structure 600 feet long and 200 feet wide, from the design of world renowned architect Eero Saarinen.

The October 1, 1996, expansion of the Terminal was a prominent milestone in the Capital Development Program. The Terminal was expanded from 600 feet in length and 500,000 square feet to 1,240 feet in length with a total of 1.1 million square feet all in accordance with Eero Saarinen’s original design.

International Arrivals Building

The International Arrivals Building opened in 1991, and provides Federal Customs and Border Protection, Agriculture and Immigration Service. In 1998, the federal government opened a secured facility in Concourse C for international passengers connecting to domestic flights on United Airlines.


Concourse C/D was completed in 1985 to serve as an interim facility and will eventually be replaced by a permanent facility. The concourse is 550,000 square feet and has 47 airline gates.

Regional Concourse A opened on May 2, 1999 with more than 110,000 square feet to serve 36 regional aircraft positions.

Concourse B opened on February 1, 1998 and was expanded in 2003 to 27 gates and 540,000 square feet. A 15-gate extension at the West End of the concourse opened January 15, 2008.  This increased the length of the 42-gate concourse to 2,810 feet and the area to 800,000 square feet.

The Z Gates opened on August 1, 2005 as a new part of the Terminal. This is a permanent 20,800-square-foot facility built with 5 airline gates, currently deployed in a 4-gate configuration.

Passenger Conveyance

The AeroTrain system opened to passengers on January 26, 2010. Read more about the construction of this system.

The airport also maintains a fleet of 19 Mobile Lounges and 30 Plane Mates, which offer a unique service transporting passengers between the Terminal and Concourses A and D.

The Mobile Lounge was designed by the Chrysler Corporation in association with the Budd Company. It is a 54-foot long, 16-foot wide, 17 1/2-foot high vehicle, weighing 76,500 pounds. A Mobile Lounge can carry 102 passengers- 71 of them seated- directly from the Terminal to the aircraft on the ramp. When the Airport opened in 1962, passengers had to walk only 200 feet once they entered the Terminal until they were seated in the Mobile Lounge for the short trip directly to their aircraft, a unique service offered only at Dulles.

The Plane Mates are 15 feet high, 15 feet wide, 54 feet long and weigh 79,300 pounds. Similar to Mobile Lounges, Plane Mates were designed so that passengers could board directly from the Plane Mate onto the aircraft, avoiding walking on the airfield.

In 2004, a new passenger walkway opened between the Terminal and Concourse B. This 1,000-foot walkway has moving sidewalks in both directions, allowing passengers an alternative route to access airline gates at Concourse B.


There are four runways at Dulles

  • 1L/19R 9,400 feet long and began service November 20, 2008.

The array of shopping and dining opportunities offered at Washington Dulles includes nearly 100 privately-owned and operated food and retail shops located throughout the airport. Many nationally and internationally recognized brands operate at Dulles. Concourse B is the centerpiece of the retail program, featuring 13,000 square feet of retail space. In all, the retail and restaurant program occupies more than 50,000 square feet at the airport.  An airport-wide Redevelopment Program began in 2013 to address the changing needs of the traveling public.
