Dulles Airport Layout

Dulles is divided into one main terminal and two midfield terminals. This makes the layout of the airport a little complicated. Always refer to your IAD Airport map when confused.

All ticketing, baggage claim, and U.S. Customs are located at the main terminal. The main terminal's only gates are the Z Gates (Air Canada Express and Frontier) and the H Gates.

  • The main concourses and most of the gates are located in the two middle terminals.
  • Concourses A and B are located in the first terminal and are home to practically all non-United Airlines flights. So, if you're flying with American Airlines or another international carrier, this is where you'll most likely arrive.
  • Concourses C and D are located in the second terminal, which is only utilized by United Airlines.

Dulles Airport Terminals

As you'll notice on the Dulles Airport parking map, the airport has a simple layout that allows travelers to move between connecting flights and areas around the airport easily.

IAD comprises one major terminal building outside the secure area and four airside concourses parallel to the terminal. Passengers can stroll between concourses or take the AeroTrain. In addition, car parking and ground transit are available outside the terminal.

The terminal is divided into two levels: departures on the upper level and arrivals on the lower level. Both levels feature outside road access for curbside drop-off and pick-up.

Ground transportation is on a third lower level outside the terminal, so the roads are divided into three levels: departures, arrivals, and ground transportation.

Four ticketing sections on the terminal's top level correspond to four drop-off places outside, depending on the airline you're flying on.

After the ticketing sections, there are two security checkpoints on either end of the terminal, which lead to the pedestrian path to the A/B gates, AeroTrain stations, Z gates, or the D gates shuttle bus.

Arrivals are on the lower level, with baggage claim covering the whole width of the terminal. It also has escalators to the departures level and security checks.

Food, Shopping, and Amenities

There are numerous retail and dining alternatives near IAD airport. Some popular shops and restaurants include Dulles Gourmet Market and Washingtonian Newsstand inside the Main Terminal at baggage claims 14 and 13. There's also a Dunkin' Donuts and Subway at the Z gates / South Finger.

Dulles Airport Security Checkpoints

The Federal TSA - Transportation Security Administration - monitors the security checkpoints at the IAD airport. Only travelers with tickets are permitted to pass through any of the security checks. Access to the concourses and airline gates is available at all security checkpoints.

From the main terminal, a moving walkway connects Concourse A with the underground passageway. After that, you'll be able to walk from one end of the lengthy terminal to the other.
