O'Hare International Airport is a major international airport located on the Northwest Side of Chicago, Illinois. It is operated by the Chicago Department of Aviation and serves as a primary hub for both American Airlines and United Airlines. As one of the busiest airports in the world, it is a critical gateway for both domestic and international travel, featuring extensive flight networks across North America, Europe, Asia, and Latin America.

History

The site's origins trace back to a Douglas Aircraft Company manufacturing plant for C-54 Skymaster military transports during World War II, originally named Orchard Field. It was renamed in 1949 to honor Edward O'Hare, a United States Navy Medal of Honor recipient from Chicago. The airport's commercial passenger operations began in 1955, and rapid expansion followed, including the iconic Terminal 1 designed by Helmut Jahn. Major developments like the completion of Terminal 5 in 1993 and the ongoing O'Hare Modernization Program have continually transformed its infrastructure to handle increasing traffic and larger aircraft like the Boeing 747 and Airbus A380.

Facilities

The airport covers over 7,200 acres and features four passenger terminals (Terminal 1, 2, 3, and 5) containing a total of nine concourses and 191 gates. Its airfield is configured with eight runways, including a set of six parallel runways that allow for maximum operational efficiency in diverse weather conditions. Notable amenities include the Hilton Chicago O'Hare Airport hotel located within the terminal complex, the Airport Transit System people mover, and extensive public art installations curated by the City of Chicago. Cargo facilities support major operators like FedEx Express and United Parcel Service.

Airlines and destinations

As a global hub, the airport is dominated by the operations of American Airlines, which maintains a large hub in Terminal 3, and United Airlines, whose primary hub is in Terminal 1. Together, they offer hundreds of daily flights to destinations across the United States. Numerous other domestic carriers, including Delta Air Lines and Southwest Airlines, and international carriers such as Lufthansa, British Airways, All Nippon Airways, and Emirates, provide service to major global cities like London, Tokyo, Frankfurt, and Dubai.

Operations and statistics

Consistently ranked among the world's busiest airports by aircraft movements, it handled approximately 73 million passengers in 2023. The Federal Aviation Administration classifies it as a Level III airport traffic coordination facility due to its high volume. Its operations are critical to the Chicago economy and national aviation networks, with continuous activity supported by advanced Air traffic control systems in the control tower. The airport is a major employer in the region, with tens of thousands working for airlines, concessions, the Transportation Security Administration, and other federal agencies.

Ground transportation

The airport is directly connected to downtown Chicago via the CTA Blue Line train, which provides rapid transit service. Multiple interstate highways, including Interstate 90 and the Tri-State Tollway, provide road access. Numerous shuttle services, taxis, and app-based ride-sharing companies operate from designated facilities. Rental car services are available from a consolidated Rental Car Facility accessible via a dedicated shuttle bus, and intercity bus service is provided by companies like Greyhound Lines.

Accidents and incidents

The airport has been the site of several notable aviation accidents. In 1979, American Airlines Flight 191, a McDonnell Douglas DC-10, crashed shortly after takeoff due to an engine detachment, resulting in the deadliest aviation accident in United States history. In 1965, a Boeing 727 operating as Eastern Air Lines Flight 663 crashed on approach. Other significant incidents include the 2005 crash of a Southwest Airlines Boeing 737 that overran a runway during a snowstorm and a 2016 incident where an American Airlines Boeing 767 aborted takeoff due to an engine fire. These events have influenced Federal Aviation Administration regulations and airport safety procedures.
