O'Hare is ranked as one of the busiest airports in the world
Chicago O'Hare International Airport, located in Illinois, United States, is one of the busiest airports in the world. As of 2024, O'Hare is the 4th busiest airport worldwide and the most connected airport in the US. It is also ranked 5th in terms of connectivity globally.
O'Hare's journey to becoming one of the world's busiest airports began in 1955, when it started as an airfield with four runways. However, it faced competition from Midway, which was then the world's busiest airport. Airlines were initially reluctant to move to O'Hare due to access issues. However, O'Hare started attracting airlines after improvements such as the opening of its first international terminal in 1958 and the completion of the expressway link to downtown Chicago in 1960. The arrival of jet airliners, such as the American 707, also played a significant role in driving airlines to relocate from Midway to O'Hare, as the latter offered more space for longer runways.
By 1962, O'Hare had become the world's busiest airport, serving 10 million passengers annually. This number doubled within two years, and O'Hare maintained its position as the world's busiest airport until 1998 when it was surpassed by Hartsfield-Jackson Atlanta International Airport.
In 2022, O'Hare retained its ranking as the 4th busiest airport in the world, handling 68.3 million passengers, a 26.5% increase from 2021. The airport offers non-stop flights to 249 destinations across multiple regions, including North America, South America, Europe, and Asia. Its central location in the United States and recent infrastructure improvements, such as the O'Hare Modernization Program, have contributed to its high volume of passenger traffic and connectivity.
