The Marine Air Terminal (also known as Terminal A) is an airport terminal located at LaGuardia Airport in Queens, New York City. Its main building, designed in the Art Deco style by William Delano of the firm Delano & Aldrich, opened in 1940. The terminal was built to handle Pan Am's fleet of flying boats, the Boeing 314 Clippers, which landed on the nearby Bowery Bay. Technological advances after World War II made the Clippers obsolete, and the Marine Air Terminal was renovated in 1946 to serve conventional planes. As of 2022, the terminal is used by Spirit Airlines flights to various destinations around the US.
