On-time performance

The industry-accepted statistic for on-time arrival of flights is called A15, measured as the percentage of flights that arrived within 15 minutes of their scheduled arrival time. While Canadian carriers are not required to report on-time performance measures, WestJet believes it is important to show our guests how we're doing. The duration of a flight is measured from the moment the parking brake is disengaged at the departure gate to the moment it is engaged at the destination gate.

WestJet reports both scheduled and system A15 results. The scheduled metric is based on our standard range of flight numbers flown in the period and is generally used for industry comparison. The system metric makes up all flights flown in the period including scheduled and unscheduled flights (rescue flights, charters, etc.).
