LaGuardia Airport was first occupied by Gala Amusement Park. Transformed in 1929 into a 105-acre private flying field, it was first named Glenn H. Curtiss Airport and later North Beach Airport. Taken over by New York City, it was enlarged by the purchase of adjoining land and by filling in 357 acres of waterfront along the east side.
Ground was broken on September 9, 1937 for a new airport, which was built jointly by the city and the Federal Works Progress Administration. It was dedicated on October 15, 1939 as New York City Municipal Airport. On November 2, 1939, the name was changed to New York Municipal Airport--LaGuardia Field. On December 2nd of that year, it was opened to commercial traffic.
In 1947, the year the airport was leased to the Port Authority, it was renamed LaGuardia Airport. A new Central Terminal Building was opened in 1964 and enlarged in 1967 and 1992.
