Chicago O'Hare International Airport (ORD)

Chicago O’Hare International Airport is one of America’s great inland hubs, a massive airfield that helped define the modern connecting airport. For travelers, its terminals, runways, and transit links reflect Chicago’s role as a national crossroads.

O’Hare is named for World War II naval aviator Edward ‘Butch’ O’Hare. Its long-running expansion and modernization efforts reflect the airport’s importance to both domestic and international air travel.

The Chicago ‘L’ Blue Line connects directly to O’Hare, making it one of the easier major hubs to reach without a car. If visiting for aviation interest rather than a flight, allow time for terminal walking distances and security boundaries.
