O'Hare's complex runway system includes four parallel pairs oriented in different directions, allowing the airport to handle simultaneous arrivals and departures in varied wind conditions. The configuration was the result of a multi-billion-dollar modernization program completed in phases between 2005 and 2021 that realigned several runways to reduce delays.
