Global Airline Reliability Improves in October, Led by Asia-Pacific as North America Faces Operational Pressures; Cirium Analysis

Cirium, the world’s most trusted source of aviation analytics, has published its October 2025 On-Time Performance (OTP) Report, covering more than 370,000 flights with 99.8% global coverage. The data indicates a 26% reduction in global cancellations compared with September, reflecting improved operational stability across the commercial aviation network. The results also highlight distinct regional dynamics shaping airline performance worldwide.

Asia-Pacific carriers led the recovery, cutting flight cancellations by 43% as airlines across Japan, South Korea, and the Philippines strengthened network performance and capacity. Notably, the world’s top-performing airports in October — Harbin Taiping and Changchun Longjia in China, and Kaohsiung International in Taiwan — were all located in the region, underscoring its continued operational gains and steady recovery momentum.

North American operations showed greater operational strain, with flight cancellations rising by about 12.6% month over month. The uptick reflects ongoing air traffic management constraints, staffing pressures, and localized weather variability that continued to test network resilience across the United States and Canada. Despite these challenges, WestJet led On-Time Performance rankings in the region, followed by Delta Air Lines and Air Canada, marking the first time in months that both Canadian carriers have ranked among the top three, a sign of growing operational consistency.

Cirium continues to monitor the impact of evolving factors in North America, including the ongoing U.S. government shutdown, which is already influencing flight operations into November. To keep abreast of the issues and receive immediate updates, contact media@cirium.com.

In North America, Canadian carriers stood out once again—proving that disciplined operations and data-driven decision-making can sustain reliability, even under pressure. Cirium’s insights continue to underscore where excellence in performance truly leads the industry.”
