O'Hare International Airport
About ORD
Overview
O'Hare International Airport sits about 27 kilometers northwest of downtown Chicago, in the U.S. state of Illinois. It serves as one of the principal international gateways to the American Midwest and ranks among the busiest airports in the world by aircraft movements. The site opened to commercial traffic in 1955, replacing Midway as Chicago's primary airfield, and was renamed in 1949 for naval aviator Edward O'Hare.
Terminals & runways
The airport operates four passenger terminals: Terminals 1, 2, and 3 handle domestic and some international flights, while Terminal 5 is dedicated to most international arrivals and departures. O'Hare functions around the clock without a curfew. It has eight runways, predominantly aligned east–west following a major reconfiguration program intended to reduce delays and increase parallel-runway capacity.
Airlines
O'Hare is a major hub for United Airlines, which maintains its operational headquarters in Chicago, and a significant hub for American Airlines. A wide range of international carriers serve the airport, including Lufthansa, British Airways, Air France, KLM, Japan Airlines, ANA, Aer Lingus, and several Star Alliance, Oneworld, and SkyTeam partners connecting Chicago with Europe, Asia, and Latin America.
