Passengers Handled at New York's Major Airports, 1989-2011

The three major airports of the metropolitan area of New York, LaGuardia (LGA), Newark Liberty International (EWR) and John F Kennedy (JFK), jointly handle more than 100 million passengers annually, making New York among the top 5 air transport markets in the world. Since the mid 2000s, passenger traffic in the New York metropolitan area has shown limited growth and signs of stagnation, particularly for EWR and LAG. EWR and JFK both cover and extensive array of international services, albeit EWR has a higher domestic orientation than JFK. LGA tends to cover almost exclusively domestic traffic, but has links with Canada (mostly Montreal and Toronto) and the Caribbean where airports have border pre-clearance facilities. While LGA is the closest airport to Manhattan, it has no room for expansion and it cannot serviced by wide body aircrafts due to the limited length of its runways. Over a 20 year period, its traffic has remained relateively constant. Stewart International Airport (SWF) is comparatively marginal, handling about half a million passengers per year.
