Cirium and OAG, two data intelligence companies in the aerospace industry, have released their January on-time performance (OTP) statistics. The figures reveal a discrepancy between the two sources.
Cirium's analysis ranks Aeromexico as the most punctual airline for January, with 89.20% of its 15,816 flights arriving on time. The airline also had a completion factor of 99.89%, with 99.73% of its flights tracked by Cirium. Iberia and Qatar Airways followed closely with OTP performances of 85.82% and 85.54%, respectively.
Delta Air Lines was recognized by Cirium as the ninth most punctual airline globally in January, despite experiencing disruptions from a CrowdStrike-caused outage in North America in 2024. However, Cirium placed Delta fourth among North American airlines behind Southwest Airlines (83.3%), Alaska Airlines (82.59%), and Spirit Airlines (81.13%).
