Baltimore/Washington International Airport serves the Baltimore, Maryland and Washington, DC metro-region. It is commonly referred to by its IATA Airport Code, BWI.
Located near Friendship Church in Anne Arundel County, Maryland, 10 miles south of Baltimore, Maryland, and 30 miles north of Washington, D.C., Friendship Airport was opened in 1950 and renamed Baltimore/Washington International Airport in 1973. Major remodeling began in 1974 and was completed in 1979. The airport is now a hub for Southwest Airlines and served about 20 million passengers in 2002. It is also the pilot airport for new security technologies in the wake of the War on Terrorism, and thus passengers may find exceptionally long waits there. The airport has been a backdrop in numerous films, including Broadcast News.
On April 12, 2005, The Maryland General Assembly approved a bill to change the name of BWI. The airport name will be changed to Baltimore/Washington International Thurgood Marshall Airport in honor of Thurgood Marshall, a former US Supreme Courtjudge who grew up in Baltimore. If the bill is signed by Governor Robert L. Ehrlich, the name change will become effective on October 1, 2005. Though the name of the airport will change, the IATA and IACO locater codes will remain the same.
