The United States of America purchased the US Virgin Islands in 1917.  The first airport on St. Thomas was a small airstrip built in the 1920s in what was known as Mosquito Bay.  Mosquito Bay was dredged, filled in, and renamed Lindbergh Bay.  On Jan. 22, 1928, the first passengers arrived on St. Thomas by air via the La Nina, a monoplane owned by the Aerial Express Co. of San Juan carrying its pilot and four passengers. 

​The US government further developed the airstrip and renamed it Bourne Field. It served primarily as an airfield for the US Military.  The airport was turned over to the VI government after the military ceased operations in the territory after World War II.  The original airport terminal was an old military hangar constructed in the 1940s and the airport was named in honor of Harry S. Truman, the 33rd President of the United States. 

​On October 3, 1984, the airport was renamed in honor of the late Governor Cyril Emmanuel King – the second elected governor of the US Virgin Islands.  Construction of the current airport terminal began in 1980 and was completed in November 1990. The runway was extended from 4,200 to its present 7,000 length in 1992. The Cyril E. King Airport features one of the largest deep-water, dredged runways in the Caribbean.
