AirTrain JFK is a 3-line, 8.1 miles (13.0 km)-long people mover system and elevated railway in New York City providing service to John F. Kennedy International Airport. It is operated by Bombardier Transportation under contract to the Port Authority of New York and New Jersey, which also operates the airport and AirTrain Newark.

AirTrain connects the airport terminals and parking areas with Long Island Rail Road (LIRR) and New York City Subway lines in Queens. The system consists of three overlapping routes:

Before separating for their final destinations, the Howard Beach and Jamaica routes stop at Federal Circle for car rental companies and shuttle buses to hotels and the airport's cargo areas. Both routes make a counterclockwise loop through the airport and stop at each terminal.

All AirTrain JFK stations are fully compliant with the Americans with Disabilities Act of 1990 (ADA) and wheelchair accessible.

With the exception of Terminal 4, all AirTrain stations are outside the terminal buildings, sit on the other side of the terminal roadway from each building and are connected to their respective stations through elevated walkways over the roadway. The Terminal 4 station was built inside the terminal as it opened after AirTrain JFK.

John Fitzgerald "Jack" Kennedy  pronunciation (help·info) (May 29, 1917 – November 22, 1963), often referred to by his initials JFK, was the 35th President of the United States, serving from 1961 until his assassination in 1963.

After military service as commander of the Motor Torpedo Boats PT-109 and PT-59 during World War II in the South Pacific, Kennedy represented Massachusetts's 11th congressional district in the U.S. House of Representatives from 1947 to 1953 as a Democrat. Thereafter, he served in the U.S. Senate from 1953 until 1960. Kennedy defeated then Vice President and Republican candidate Richard Nixon in the 1960 U.S. presidential election. He was the youngest elected to the office, at the age of 43, the second-youngest President (after Theodore Roosevelt), and the first person born in the 20th century to serve as president. Kennedy is the only Catholic president, and is the only president to have won a Pulitzer Prize. Events during his presidency included the Bay of Pigs Invasion, the Cuban Missile Crisis, the building of the Berlin Wall, the Space Race, the African American Civil Rights Movement, and early stages of the Vietnam War.
