What is a common challenge faced by travelers at O'Hare Airport?

The correct answer is centered around the high percentage of flight delays that travelers commonly experience at O'Hare Airport. O'Hare is known for being one of the busiest airports in the world, which can contribute to congestion both in the air and on the ground. Various factors, such as weather conditions, air traffic control restrictions, and high volumes of passenger traffic, often lead to delays. Understanding this challenge is crucial for travelers to plan appropriately, as it can affect their overall travel experience, connection times, and expectations.

While the airport does offer a wide array of travel options, this abundance is not typically seen as a challenge but rather a benefit. Limited lounge access, while it may affect some travelers, is not universally seen as a primary challenge at O'Hare given its extensive amenities. Lastly, low passenger traffic is not a concern at this airport, as it is usually bustling with activity, and does not pose a challenge in the same way that delays do.
