WestJet completes five consecutive months as North America's most punctual airline.
WestJet has secured its position as North America’s most punctual airline for the fifth consecutive month, recording an 85.31 per cent on-time arrival rate across approximately 17,390 completed flights in September 2026. According to the latest monthly On-Time Performance Report published by aviation analytics firm Cirium, the Canadian carrier extended its operational leadership over regional competitors through the high-volume summer peak and into autumn.
The performance places WestJet nearly three percentage points ahead of the second-ranked North American airline, highlighting consistent flight execution across its domestic Canadian and international network.
Executive Recognition and Operational Coordination
WestJet leadership attributed the multi-month streak to cross-departmental coordination across flight crews, maintenance teams, airport ground handlers, and network operations centers.
"This achievement would not be possible without the incredible dedication of WestJetters across our network, from flight crews and maintenance teams to airport, network, customer service and operations teams," said Diederik Pen, President of WestJet Airlines and Chief Operating Officer of the WestJet Group. "Maintaining this performance for five consecutive months, particularly through the peak summer travel season, is a testament to the care, teamwork and operational excellence our people bring to work every day."
Pen emphasized that while the carrier is preparing for the winter travel period—a season historically vulnerable to severe weather delays in Canada—the ongoing focus remains on schedule reliability and passenger trust: "Our guests count on us to get them where they need to go safely and reliably, and while we know there is always more to do and head into our busy winter season, we are proud of the progress we are making."
