The Washington Dulles International Airport (IAD), also called Dulles Airport, is in Virginia, west of Downtown Washington DC. Dulles is the region's international air hub with dozens of nonstop international flights. Dulles has the highest international passenger traffic of any Mid-Atlantic airport outside of the New York metropolitan area, accounting for around 90% of foreign passenger traffic in the Baltimore–Washington region. The IAD Airport handles more than 20 million passengers annually.
As you'll see on the IAD parking map, there are three onsite parking lots at the airport and several offsiteIAD parking lots nearby.
At 20.3 square miles, IAD is one of the largest airports in the world and also one of the biggest in the U.S. The Dulles Airport parking map above will help you navigate this airport.

As you'll notice on the Dulles Airport parking map, the airport has a simple layout that allows travelers to easily move between connecting flights and areas around the airport.
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.
Arrivals are on the lower level, with baggage claims covering the entire width of the terminal. It also has escalators to the departure level and security checks.

Dulles International Airport was named to honor John Foster Dulles, the late Secretary of State. Thus, the three-letter code for Dulles International Airport was DIA. However, when written by hand, it was frequently misinterpreted as DCA, another Washington airport. Therefore, to minimize confusion, it was changed to IAD.
