AirTrain JFK connects the airport's terminals and parking areas with the Howard Beach and Jamaica stations.
It is located entirely within the New York City borough of Queens.
The system consists of three routes: two connecting the terminals with either the Howard Beach or Jamaica stations, and one route looping continuously around the central terminal area.
It is operated by Bombardier under contract to the Port Authority.

The Howard Beach Train route (colored green on the official map) begins and ends at the Howard Beach–JFK Airport station, where there is a direct transfer to the New York City Subway's A train.
It makes an additional stop at Lefferts Boulevard, where passengers can transfer to parking lot shuttle buses; the B15 bus to Brooklyn; and the limited-stop Q10 bus.
The segment from Howard Beach to Federal Circle, which is about 1.8 miles (2.9 km) long, passes over the long-term and employee parking lots.

The Jamaica Station Train route (colored red on the official map) begins and ends at the Jamaica station, adjacent to the Long Island Rail Road platforms there.
The Jamaica station contains a connection to the Sutphin Boulevard–Archer Avenue–JFK Airport station on the New York City Subway's E​, ​J, and ​Z trains.
The AirTrain and LIRR stations contain transfers to the subway, as well as to ground-level bus routes.
West of Jamaica, the line travels above the north side of 94th Avenue before curving southward onto the Van Wyck Expressway.
The segment from Jamaica to Federal Circle is about 3.1 miles (5.0 km) long.

The Howard Beach Train and Jamaica Station Train routes merge at Federal Circle for car rental companies and shuttle buses to hotels and the airport's cargo areas.
South of Federal Circle, the routes share track for 1.5 miles (2.4 km) and enter a tunnel before the tracks separate in two directions for the 2-mile (3.2 km) terminal loop.
Both routes continue counterclockwise around the loop, stopping at Terminals 1, 2, 4, 5, 7, and 8 in that order.
 Connections to the Q3, Q10, and B15 local buses are available at Terminal 5.
The travel time from either Jamaica or Howard Beach to the JFK terminals is about eight minutes.

The Airline Terminals Train (colored gold on the official map), an airport terminal circulator, serves the terminals.
It makes a continuous clockwise loop around the terminals, operating in the opposite direction to the Howard Beach Train and Jamaica Station Train routes.
The terminal-area loop is 1.8 miles (2.9 km) long.

Trains to and from Jamaica and Howard Beach were originally planned to run every two minutes during peak hours, with alternate trains traveling to each branch.
The final environmental impact statement projected that trains in the central terminal area would run every ninety seconds.
By 2014 actual frequencies were much lower: each branch was served by one train every seven to 12 minutes during peak hours.
Trains arrived every 10 to 15 minutes on each branch during weekdays; every 15 to 20 minutes during late nights; and every 16 minutes during weekends.
