History of JFK International Airport In April 1942, New York City began placing hydraulic fill over the marshy tidelands of Idlewild Golf Course. Initial plans were for a modest 1,000-acre airport, but by the time construction was complete Idlewild Airport had grown to five times that size. Commercial flights began in July 1948. On December 24, 1963, the airport was rededicated John F. Kennedy International Airport in memory of the nationâs 35th president. Today, JFK is the nationâs leading international gateway, with more than 80 airlines operating from its gates.
