About Chicago O'Hare International Airport

Chicago O'Hare International Airport Neon Lights

Chicago O'Hare International Airport is the largest airport in Chicago. It was built in 1995 and instantly became the main airport in Chicago as it overtook Chicago Midway International by passenger traffic and size.

The airport was the first major airport built post World War II and was the world's busiest airport from the early 1960s up until the late 1990s. Today, it remains as one of the top 10 busiest airports in the world, with over 80 million passengers served per year.

Chicago O'Hare underwent a major expansion in 1962 with the creation of Terminal 2 and 3. It expanded again in 1985 when United built a new Terminal 1 that featured two concourses. Additional terminals were built in the years following. The terminals are numbered 1–5, with Terminal 4 no longest existing.

Chicago O'Hare will undergo a massive terminal redevelopment plan that will see all terminal floor spaces expand. All redevelopment is set to be finished by 2028.

The airport is a major hub for both American Airlines and United Airlines.
