In 2026, the primary way to move between terminals at John F. Kennedy International Airport (JFK) is via the AirTrain JFK. This automated people mover operates 24/7 and circles the airport, connecting all active passenger terminals (Terminal 1, 4, 5, 7, and 8). The AirTrain is free to use for inter-terminal travel; you only pay a fee if you are entering or exiting the system at the Jamaica or Howard Beach off-airport stations. Because JFK is currently undergoing a multi-billion dollar "New Terminal One" and "Terminal 6" construction project, some walking paths and shuttle bus stops have changed. For example, if you are transferring between Terminal 5 and Terminal 7, the AirTrain is the only viable option. It is important to remember that most terminal transfers at JFK require you to exit the secure area, take the AirTrain, and then re-clear TSA security at your next terminal. If you are on an international-to-domestic connection, you must also collect your checked bags at Customs and re-check them before heading to the AirTrain, so you should allow at least 2–3 hours for any terminal-to-terminal transfer.
