The U.S. Marshals’ Justice Prisoner and Alien Transportation System (JPATS) manages the coordination, scheduling and secure handling of prisoners in federal custody, transporting them to detention facilities, courts and correctional institutions via a network of aircraft, buses, vans and cars. JPATS is the largest transporter of prisoners in the United States, supporting the federal judiciary, U.S. Marshals district offices and the Federal Bureau of Prisons. JPATS is the only government-operated, regularly-scheduled passenger airline in the nation. It transports prisoners using more than 40 airlift sites throughout the U.S. and its territories. JPATS air operations are conducted using JPATS-owned and -leased aircraft operated by specially trained aviation security staff, expert pilots, medical personnel and experienced mechanics. JPATS operates a fleet of aircraft to move prisoners over long distances more economically and with higher security than commercial airlines.
