The Airport Transit System (ATS) is an automated people mover system at Chicago O'Hare International Airport. It opened on May 6, 1993. The ATS moves passengers between the airport terminals and parking facilities, and was designed to operate 24 hours a day, 7 days a week. The system was closed for refurbishment and modernization between January 2019 and November 2021.
