The New York metropolitan area has the busiest airport system in the United States and the second-busiest in the world after London. It is the country's most frequently used port of entry and departure for international flights.
The metro area has three major airports: John F. Kennedy International Airport (JFK), Newark Liberty International Airport (EWR) and LaGuardia Airport (LGA), all operated since 1947 by the Port Authority of New York and New Jersey.[1] In 2014, they were used by more than 117 million passengers.[2][3][4] Until 2022, the three shared the International Air Transport Association airport code (IATA code) "NYC"; Newark now only uses EWR.[5] JFK and Newark are connected to regional rail systems by AirTrain JFK and AirTrain Newark respectively.
The class B airspace used by the three airports is extremely congested. The Federal Aviation Administration (FAA) limits the number of flights per hour but they rank among the top five airports in the United States for delays.[6][7]
The area also includes several satellite or reliever airports that provide commercial air carrier service on a much smaller scale as well as numerous general aviation airports, heliports, and seaplane bases.[8]
Under the terms of agreements with the City of New York, dated April 17, 1947, and with the City of Newark, dated October 22, 1947, The Port Authority of New York and New Jersey is responsible for the improvement, development, operation and maintenance of LaGuardia Airport, John F. Kennedy International Airport and Newark Liberty International Airport.
