Washington Dulles International Airport ( DUL -iss ) (IATA : IAD , ICAO : KIAD , FAA LID : IAD ) – commonly known by its former name of Dulles International Airport , by its airport code of IAD , or simply as Dulles Airport – is an international airport in the Eastern United States , located 26 miles (42 km) west of downtown Washington, D.C. , in Loudoun and Fairfax counties in Northern Virginia .[ 5] [ 6]
Opened in 1962, the airport is named after John Foster Dulles , an influential secretary of state during the Cold War who briefly represented New York in the United States Senate .[ 7] [ 8] Its main terminal was designed by Eero Saarinen , who also designed the TWA Flight Center at John F. Kennedy International Airport . Operated by the Metropolitan Washington Airports Authority , Dulles occupies 13,000 acres (20.3 sq mi; 52.6 km2 ),[ 3] [ 9] straddling the Loudoun–Fairfax line.[ 10] IAD ranks fourth in the US in terms of land area, after Denver International Airport , Dallas/Fort Worth International Airport , and Southwest Florida International Airport . Most of the airport is in the unincorporated community of Dulles in Loudoun County , with a small portion in the unincorporated community of Chantilly in Fairfax County.
Along with Ronald Reagan Washington National Airport (DCA) and Baltimore/Washington International Airport (BWI), Dulles is one of three major airports serving the Washington–Baltimore metropolitan area . As of 2024, it is the busiest airport in the Washington–Baltimore metropolitan and the 28th-busiest airport in the United States. [ 11] Dulles has the most international passenger traffic of any airport in the Mid-Atlantic outside the New York metropolitan area , including approximately 90% of the international passenger traffic in the Baltimore–Washington region.[ 12] It had more than 20 million passenger enplanements every year from 2004 to 2019, with 27.3 million enplanements in 2024.[ 13] An average of 60,000 passengers pass through Dulles daily to and from more than 139 destinations around the world.[ 14] [ 15] [ 16]
Increased domestic travel from Reagan National Airport has eroded some of Dulles's domestic routes.[ 11] Dulles overtook Reagan in total enplanements in 2019.[ 17] In 2018, however, Dulles surpassed Reagan in yearly passenger boardings after having fewer passengers since 2015.[ 18] Furthermore, it still ranks behind BWI in total annual passenger boardings.[ 19]
In 2024, IAD set an all-time passenger record, with 27.25 million passengers, breaking the record set in 2005.[ 13]
Dulles is a hub for United Airlines and is frequently used by Star Alliance members like Turkish Airlines and Lufthansa , that United has codeshare agreements with. Dulles is also a hub for regional operators Mesa , GoJet , and CommuteAir , who operate under the United Express brand.
