On a global scale, WestJet ranks 15th among low-cost carriers with a 78.9% on-time performance rating while Skymark Airlines in Japan took the top spot with a 90.1% rating.

The report says the Toronto-based airline's on-time performance was 66%.

Calgary and Edmonton were the only Canadian airports to reach the top 20 for on-time performance, placing 17th and 20th in the large and medium categories, respectively.
