Ronald Reagan Washington National Airport (IATA: DCA, ICAO: KDCA) in Arlington County, Virginia is a commercial airport notable for being the nearest to Washington, D.C.

Originally named Washington National Airport, the facility was renamed Ronald Reagan Washington National Airport after former President Ronald Reagan in 1998. The airport is commonly known as “National”, “Washington National”, “Reagan”, and “Reagan National”; “DCA” is used as the main airport code.

The airport is a focus city for US Airways, also the airport’s largest carrier. The US Airways Shuttle offers air shuttle service to LaGuardia Airport in New York City and Logan International Airport in Boston, Massachusetts. Delta Air Lines’ Delta Shuttle offers air shuttle service to LaGuardia Airport in New York City. With a handful of exceptions, flights are restricted to destinations within 1,250 miles (2,012 km), in an effort to control aviation noise and to drive air traffic to the larger but more distant Washington Dulles International Airport. In 2006, the airport served approximately 18.5 million passengers.[1] Because the airport lacks U.S. immigration and customs facilities, the only international flights operating out of DCA go to airports with U.S. Customs and Border Protection preclearance, which include Nassau, Bahamas; Bermuda; Toronto, Ontario; and Montreal, Quebec.
