Chicago O'Hare International Airport[a] (IATA: ORD, ICAO: KORD, FAALID: ORD) is a major international airport serving Chicago, Illinois, located on the city's Northwest Side, approximately 17 miles (27 km) northwest of the Loop business district. Operated by the Chicago Department of Aviation[4] and covering 7,627 acres (3,087 ha),[5][6] O'Hare has non-stop flights to 214 destinations in North America, South America, the Caribbean, Europe, Africa, Asia, the Middle East, Oceania, and the North Atlantic region as of November 2022.[7][8] As of 2023, O'Hare is considered the world's most connected airport.[9] It is also U.S.A.'s 4th busiest airport, and 7th biggest airport.
Designed to be the successor to Chicago's Midway International Airport, itself once nicknamed the "busiest square mile in the world," O'Hare began as an airfield serving a Douglas manufacturing plant for C-54 military transports during World War II. It was renamed Orchard Field Airport in the mid-1940s and assigned the IATA code ORD. In 1949, it was renamed after aviator Edward "Butch" O'Hare, the U.S. Navy's first Medal of Honor recipient during that war.[10][11] As the first major airport planned after World War II, O'Hare's innovative design pioneered concepts such as concourses, direct highway access to the terminal, jet bridges, and underground refueling systems.[12]
