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

10. Air Canada – Delay-Prone Cross-Border Hubs

Air Canada’s reputation for cancellations stems largely from its congested hub cities—Toronto and Montreal—where weather delays and customs bottlenecks often derail schedules. Add in cross-border complexities and outdated airport infrastructure, and the odds of a smooth trip start to drop. During peak travel periods, flight disruptions are especially common. If flying Air Canada, opt for nonstop routes when possible and consider early morning departures to minimize exposure to the day's cumulative delays. Enrolling in the airline’s alerts system and having backup transportation plans can also help reduce travel-day stress.
