14 Airlines Most Likely to Cancel Your Flight (And How to Avoid Them)

12. WestJet – Regional Exposure and Staff Gaps

WestJet’s affordable fares make it appealing, but its operational reliability has taken a hit due to pilot shortages and overextended route expansions, especially in Western Canada. Regional routes are more vulnerable to weather, and staffing gaps can quickly escalate into mass cancellations. The airline is working to stabilize its network, but travelers should keep itineraries flexible and monitor strike news or service alerts. If you're flying to or from smaller airports, double-check alternative options and avoid booking critical connections too close together.
