Chicago O’Hare Airport History

The origins of Chicago O’Hare International Airport date back to WWII. At that time, it was called “Douglas Airport,” a manufacturing plant with an airfield and train connections. It was primarily used to build C-54s for WWII. The Douglas Airport location was previously known as Orchard Place, which used to be farming land. 

Once WWII ended, the military and city of Chicago took over operations at Douglas Airport and massive redesigns and expansions took place. The latest airport designs and ideas of the time were implemented. For example, it made use of underground fueling, provided access to the highway and train system, and featured concourses and jet bridges. 

In 1955, Chicago O’Hare began serving passengers. ORD continued to grow with the introduction of new jet planes since ORD offered more space than Chicago’s other airport, Midway. By 1961, O’Hare had become the second busiest airport in America.

O’Hare’s terminals expanded significantly between the 1980s and 1990s. United Airlines has a hub at ORD in Terminal 1 and American Airlines has a hub in Terminal 3. Terminal 5 was added in 1993 and serves as the main terminal for international flights from around the world. O’Hare has eight runways in all, with six parallel runways and four terminals in total. 

Today, O’Hare continues to be one of the busiest airports in America, and even the world. It’s the gateway into America’s Midwest, and it serves millions of travelers every year. ORD connects people to the best of Chicago, from museums and parks, to food, and more.
