Chicago O'Hare International Airport
O'Hare International Airport (ORD) in Chicago is one of the busiest airports in the world by aircraft movements and a primary hub for both United Airlines and American Airlines. Its ICAO-style three-letter code doesn't match its name because it predates the airport's current identity: the site opened in the 1940s as Orchard Field, a wartime aircraft manufacturing plant, and "ORD" — short for Orchard — stuck even after the airport was renamed in 1949 to honor World War II naval aviator Edward "Butch" O'Hare. O'Hare has eight runways, more than almost any other commercial airport.
