Dulles International Airport (IAD) is one of three airports servicing the U.S. capital. It is situated about 26 miles outside Washington, D.C., in the Northern Virginia suburbs.
Compared to its counterpart in Virginia, Ronald Reagan Washington National Airport, Dulles’ footprint is far larger. After all, Washington-Dulles is known for its vast international flight options. Plus, it's a major United Airlines hub, and it's got that iconic main terminal, designed by well-known architect Eero Saarinen (the same architect who brought the New York-JFK terminal that’s now the TWA hotel to life).
IAD map
Washington-Dulles consists of a main terminal building which features ticketing, security and a small set of “Z” gates, plus baggage claim and customs on the bottom floor.
There are two separate midfield terminals that run parallel to the main terminal: one long building housing the A and B concourses, and another housing the C and D concourses.
Map of IAD terminals
Dulles Airport main terminal
The Washington-Dulles main terminal building is the immediately-recognizable structure most people think of when picturing the airport, with its vaulted ceiling and all-glass facade.
The main terminal is divided into two floors: departures upstairs and arrivals downstairs.
Upper level
Inside the main terminal on the upper level, there are four large islands with ticket counters for domestic and international airlines.
There is also separate security for CLEAR+ and TSA PreCheck members.
Once you pass through security, you’ll catch the Aerotrain or people movers to your specific departure terminal.
Downstairs
Downstairs on the arrivals level is baggage claim, as well as the airport’s customs facilities, which include Global Entry access.
Food options
- Pre-security: Cafe Americana, District Chophouse, Capitol Grounds Coffee.
Retail
- International Currency Exchange, Dulles Gourmet Market.
Lounges
The main terminal building houses a Capital One Lounge just beyond the TSA PreCheck lanes.
Transportation
Since Dulles operates out of three main terminal buildings, travelers have to take transportation to move between each.
Aerotrain
The most convenient option is the Washington-Dulles Aerotrain, an automated train system that runs between a few of the terminals. It’s usually a quick ride, with a maximum of two minutes between stations.
You can take the Aerotrain if you have a flight in the A gates, B gates or C gates. However, note that it is a decent walk from the station to the C gates.
People movers
One of Dulles’ best-known quirks is its “mobile lounges,” or “people movers.” These Star Wars-esque machines haven’t entirely been phased out with the Aerotrain.
Inside, the people movers feel like a combination of a waiting room and a bus, and they take passengers from one terminal to another.
You’ll typically ride the people movers if you’re:
- Flying out of the D gates (one of United’s concourses).
- Connecting between United’s D gates and Terminal A (gates A1A through A6F).
- Arriving on an international flight to get to the customs area in the main terminal.
Passenger walkway
If you’d rather get some steps in, there’s also a 1,000-foot underground pedestrian walkway that connects the main terminal with Concourse B, featuring moving sidewalks in both directions.

Parking
Washington-Dulles has several parking options. The priciest are right near the terminal and in garages, and the most affordable is a cheaper, satellite economy lot requiring a shuttle. You can reserve your parking online or take your chances of finding a free spot at the airport.
Terminal parking
- Most expensive option.
- Located just in front of terminal.
- Follow covered walkway to terminal (brief walk).
- There’s an additional “Valet” parking option that allows convenient pickup in front of the terminal parking lot for ultra convenience.
Garage 1 or Garage 2 Parking
- Parking garage close to terminal.
- Walk to the terminal via an underground or covered pedestrian walkway or take a shuttle.
- Garage 2 is the most convenient for international departures.
Economy parking
- Satellite parking lot.
- Cheapest option.
- Shuttle service runs every 15 minutes. Give yourself at least 15 minutes of travel time to the terminal.
Rental cars
To get to and from the rental car facilities, you’ll have to take one of the airport’s free shuttle buses, a few minutes’ ride. Dulles has most major rental car companies.
Washington Metro Access
Dulles has direct access to the Washington Metro system via the Silver Line station. It’s located opposite the main terminal, across the terminal parking facilities. You’ll take an underground path with moving walkways to get to the Silver Line station.
From there, you can catch a Metro train that will take you through Tyson’s Corner, and eventually through Rosslyn and into downtown D.C. Metro’s trip planner shows it’s a ride of more than 50 minutes to Metro Center, a key connecting station in downtown D.C.
Check Metro’s website for information on hours of operation and fares.
Uber/Lyft from Dulles
Customers hoping to use a rideshare service like Uber and Lyft when they get off the airplane can be picked up on the arrivals level outside baggage claim outside Doors 2, 4 and 6.
