Main Terminal / Concourses at Washington Dulles IAD Airport

Terminal layout of IAD Airport, Important Notices, Getting around, International Arrivals, Transportation/ Connections, Main Terminal & Midfield Concourse Details:

The passenger terminal complex at Washington Dulles International Airport consists of a large Main Passenger Terminal , recognized by its curved roof, with connected Z gates, and two Midfield Concourse buildings (parallel to each other) - the first of which houses the  A gates west & B gates east;  the second houses C gates west and D gates east.  Temporary Midfield Concourses C & D (a new Concourse will eventually replace them) cannot be reached by foot (except C-to-D gates)  and need to be accessed partly by Aerotrain (to C gates with walkway to D gates) or shuttle bus (to D gates).  
The Main Terminal is connected to the Hourly Parking Lot & the Daily Garage 1 by an enclosed walkway with moving sidewalks. Attached to the right of the Main Terminal is the International Arrivals Building Z gates  are near the passenger walkway to A&B gates, and the entrance to the subway (after security check take the elevator to the Z gates Z6-10).  H gates are opposite of Z gates (with Air Tower in between) - but H gates are only accessible via shuttle bus.

1. IAD is designed to serve up to 2,400 passengers an hour. During the busiest airport hours of 5:30am - 8am, 11am - 1pm, and 3:30pm - 5:30pm, it is advisable to arrive at the Main Terminal no later than two hours prior to scheduled domestic flights and three hours for international flights.

4. Waiting times at the Main Terminal's east & west security mezzanine-level checkpoints are displayed in real time - you can opt for the line with the shortest waiting time.
Getting around:  Concourses A & B are served separately by the underground AeroTrain, but can also be accessed from the main terminal via moving walkway.  A permanent midfield concourse station has access to Concourse C by means of a tunnel with moving walkways. However, mobile lounges still serve the D Concourse from both the main terminal and the A Concourse.  H & Z gates are reached from the Terminal by short shutte ride.
Departing passengers: Follow signs 'TO ALL GATES', after going through security checkpoint, look for signs to gate areas. If heading to A, B or C gates - the AeroTrain signs will guide you to them (you can also use the moving walkways to A & B gates). If connecting to the D gates, take shuttle bus, running every 15 mins.
Arriving passengers: Follow signs 'TO BAGGAGE CLAIM / GROUND TRANSPORTATION'; domestic arrivals at A, B or C gates should follow the AeroTrain sign; international arrivals will board the shuttle to US Customs (see below).

International Arrivals: 
All international arrivals at IAD are being transported to the International Arrivals Building (IAB) at the west end of the main terminal for TSA clearance. IAB streamlines its passenger flow from the Arrivals Hall all the way through to the passenger greeting area (and down the escalator to the underground AeroTrain for connecting to Concourses A, B & C. Unless you have gone through US customs clearance by participating airports, you need to go through passport check, retrieve checked bags, go through customs clearance and - if transferring to another flight - re-check-in bag. NOTE: International arrivals who continue their journey at D gates (at Midfield Concourse C/D) cannot use the AeroTrain, but need to take the Mobile Lounge shuttle at Main Terminal's lower level  to gates D1-32.

Also, a shuttle bus to the A gates departs near gate D11 & Starbucks. D gates are currently not served by the AeroTrain, but by shuttle bus from/to the main terminal. (Concourses C & D are temporary and will upon completion be replaced by a new Concourse near the Air Traffic Tower.)
