Terminal A, known as the Marine Air Terminal (MAT), was the airport's original terminal for overseas flights.
The waterside terminal was designed to serve the fleet of flying boats, or Clippers, of Pan American Airways, America's main international airline throughout the 1930s and 1940s.
When a Clipper landed in Long Island Sound, it taxied to a dock where passengers could disembark into the terminal.
During World War II new four-engine land planes were developed, and flying boats stopped carrying scheduled passengers out of New York after 1947.
The last Pan American flight left the terminal in February 1952, bound for Bermuda.

Inside the terminal hangs Flight, a mural measuring 12 feet (3.7 m) in height and 237 feet (72 m) in length; it was the largest mural created as part of the Great Depression-era Works Progress Administration (WPA).
Completed by James Brooks in 1942, Flight depicts the history of man's involvement with flight.
The mural was painted over without explanation by the Port Authority of New York & New Jersey in the 1950s, possibly because some saw left-wing symbolism in it.
After an extensive restoration project headed by aviation historian Geoffrey Arend, the mural was rededicated in 1980.

In 1986, Pan Am restarted flights at the MAT with the purchase of New York Air's shuttle service between Boston, New York City, and Washington, D.C. In 1991, Delta Air Lines bought the Pan Am Shuttle and subsequently started service from the MAT on September 1.
In 1995, the MAT was designated as a historic landmark.
A $7 million restoration was completed in time for the airport's 65th anniversary of commercial flights on December 2, 2004.
On December 9, 2017, JetBlue and Alaska Airlines relocated to the MAT while Delta consolidated all Delta Shuttle flights to Terminal C. On October 27, 2018, Alaska Airlines ended all service from LaGuardia Airport, leaving JetBlue as the terminal's only tenant.
