O'Hare International Airport has reclaimed its position as the busiest airfield in the world, according to new data released by Airports Council International (ACI) World. In 2025, O'Hare recorded 860,015 aircraft operations, a 10.8% increase over 2024, solidifying Chicago's role as a global hub for commerce, travel, and connectivity.

Why it matters

Being home to the world's busiest airport is a point of pride for Chicago, reflecting the city's enduring strength as a global economic engine. O'Hare's return to the top spot underscores its unmatched operational capacity, powered by an advanced airfield configuration and global connectivity, positioning it as a premier cargo hub and a critical component of the national aviation system.

The details

O'Hare's record-breaking performance in 2025 was driven by an 8-runway system developed over 16 years, making it the most advanced airfield configuration of any civilian airport globally. The airport's deep regional reach, global connectivity, and strength as a cargo hub also contributed to its rise to the top. To maintain this status, the city is investing $8.2 billion in the ORDNext program, which includes 43 new gates and the transformative O'Hare Global Terminal.
