John F. Kennedy International Airport is one of the nation’s leading international gateways. It is located in the borough of Queens in New York City. It is owned by the City of New York and managed by the Port Authority of New York and New Jersey under a long-term operating lease. It is the busiest international airport and the third biggest freight gateway in value of shipments in the United States.  It was known as Idlewild Airport until 1963, when it was rededicated John F. Kennedy International Airport in memory of the 35th President of the United States. JFK was constructed to reduce the volume of traffic in LaGuardia Airport. Since 1947 the Port Authority leased the JFK property from the City of New York and has continued since. The Port Authority annulled the contract with foreign airlines to use LaGuardia, encouraging them to move to JFK for within the next few years. When the Port Authority intended to build a single 55-gate terminal, the major airline insisted the scale was too small considering the expected traffic in the future. Architect Wallace Harrison laid out a master plan that allows each major airline at the airport to develop its own terminal design. This plan made construction more efficient and terminals more navigable and brought advantage for airlines to compete with each other with the best arrangement. Five terminals for each airline, one for three airlines, and an international arrivals building were designed in 1955. JFK started serving jet aircraft in 1958; LaGuardia did not serve jets until 1964. JFK became New York’s busiest airline airport and handled more airlines than the total of LaGuardia and Newark, peaking at 403,981 airline operations in 1967. Construction of the AirTrain JFK began in 1998 and was completed in 2003. It connected the rail network of each airport terminal to New York City subways. In 2007 JFK became the first airport to receive the Airbus A380 in United States. JFK has six operating airline terminals including 128 gates numbered 1 to 8 but without Terminals 3 and 6. Terminal 1 was opened in 1998 with a partnership with four key operating airlines: Air France, Japan Airlines, Korean Air and Lufthansa. Terminal 2 opened in 1962 as the home of Northeast Airlines, Braniff and Northwest Airlines, and now it is solely used by Delta Air Lines. Terminal 4 is a major international hub for Delta Air Lines and the major gateway for International arrivals at JFK. Terminal 5 opened in 2008 and serves JetBlue Airways as their base in JFK. Terminal 7 was built for BOASC and Air Canada in 1970 and now managed by British Airways. Terminal 8 was designed by American Airlines to construct the largest terminal at JFK. It contains U.S. Customs and Boarder Protection facilities, 84 ticket counters, and 10 security checkpoint lanes. Terminal 8 handles 12.9 million passengers a year. About $150 million was expended for initial development. The Port Authority has invested about $7 billion more. About 37,000 employees are working at JFK and the airport contributes about $37.3 billion in economic activity to the New York-New Jersey metropolitan area, leading to about 256,000 jobs in the region.
