What is O'Hare Airport's status in terms of air traffic and flight operations?

O'Hare Airport is recognized as one of the busiest airports in the world, with a high volume of air traffic and extensive flight operations. Its location in Chicago makes it a crucial hub for both domestic and international flights. O'Hare serves millions of passengers annually and supports a vast network of airlines, contributing significantly to its status as a major player in global air travel. The airport's infrastructure, including multiple runways and terminals, is designed to accommodate this high level of activity efficiently, enabling it to handle a large number of takeoffs and landings each day. This operational scale underscores its prominent role in aviation, distinguishing it from smaller or less busy airports. Other options reflect characteristics that do not align with O'Hare's status, such as being a private airport or having low flight operations.
