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

19. IndiGo – Volume Overload Meets Limited Resilience

India’s largest airline, IndiGo moves millions of passengers annually—but that high volume comes with risk. Rapid expansion has outpaced infrastructure improvements at key airports, and the airline’s tight fleet utilization means any mechanical issue or ATC delay can cause cascading cancellations. Monsoon season adds another layer of unpredictability. To minimize risk, fly early in the day, avoid flights during peak festival seasons, and use the airline’s app for live updates. Also consider booking directly—customer service is notoriously better for direct bookings versus third-party platforms.
