Newark Liberty International Airport- EWR, first named Newark Metropolitan Airport and later Newark International Airport, is an international airport which straddles the municipal boundary between Newark and Elizabeth, New Jersey, United States. The airport is owned by the city of Newark and operated by the Port Authority of New York and New Jersey. It is about 15 miles southwest of Midtown Manhattan in New York City. Newark Airport was the first major airport in the United States and is the New York-New Jersey metropolitan area's busiest in terms of flights.
The airports in the Port of New York and New Jersey combine to create the largest airport system in the United States, second in the world in terms of passenger traffic, and first in the world in terms of total flight operations. In 2011, Newark Airport handled 33.8 million passengers, JFK International handled 47.8 million, and LaGuardia's just over 24.0 million.
Newark Liberty is the third-largest hub for United Airlines (after Houston and Chicago-O'Hare), which is the airport's largest tenant (operating all of Terminal C and part of Terminal A). Primarily due to this large hub operation, United Airlines is by far the leading carrier in the New York market. Newark's second largest tenant is FedEx Express, whose third largest cargo hub uses three buildings on two million square feet.
