The Chicago Department of Aviation (CDA) and Airports Council International (ACI) World have reported that O'Hare International Airport was the second-busiest airport globally for aircraft movements in 2024, and the eighth busiest for passenger traffic.
Mayor Brandon Johnson stated, "Chicago has long stood at the crossroads of global travel and commerce, and O’Hare’s ranking as the world’s second-busiest airport for aircraft movements is a powerful reflection of that legacy.” The mayor attributed this achievement to the dedication of Chicago's workforce and the effective management by the CDA.
CDA Commissioner Jamie L. Rhee expressed her gratitude to the agency's staff, noting, “I’m incredibly grateful to our frontline CDA staff for their tireless dedication to ensuring Chicago’s airports operate safely, efficiently, and reliably — even amid growing demand.” She underlined the team's efforts under the O’Hare 21 capital program to modernize the airport.
