Airport HistoryEst. 1950

Opened in 1950 as Friendship International Airport on farmland near Linthicum Heights, Maryland, the airport was dedicated by President Harry Truman. Purchased by the State of Maryland in 1972 and renamed Baltimore/Washington International in 1973, it was rededicated in 2005 in honor of U.S. Supreme Court Justice Thurgood Marshall, a Baltimore native. Today it is a major Southwest Airlines base and one of three primary airports serving the Washington-Baltimore region.

✦The airport's original name, 'Friendship,' came from the nearby community of Friendship, Maryland, chosen to reflect postwar international goodwill.
✦Southwest Airlines is by far the dominant carrier, accounting for over 70% of passengers (Sept 2023-Aug 2024 data).
