Ronald Reagan Washington National Airport (IATA: DCA, ICAO: KDCA, FAA LID: DCA) is a public airport in Arlington County, Virginia, United States, five miles (eight kilometers; four nautical miles) from Washington, D.C. The closest airport to the nation's capital, it is one of two airports owned by the federal government and operated by the Metropolitan Washington Airports Authority (MWAA) that serve the Washington metropolitan area; the other is Dulles International Airport (IAD), located about 25 miles (40 km; 22 nmi) to the west in Fairfax and Loudoun counties.
The airport opened in 1941 and was originally named Washington National Airport. Part of the original terminal is still in use as Terminal 1. The much larger Terminal 2 opened in 1997. In 1998, Congress passed and President Bill Clinton signed a bill renaming the airport in honor of the 40th president of the United States, Ronald Reagan, who was in office from 1981 to 1989.
