What’s Behind IndiGo’s Widespread Flight Disruptions?

Think of a friend who plans everything down to the minute. Last week, one of my friend walked into the airport expecting a normal travel day, only to find terminals overflowing, display boards bleeding red, and every second announcement starting with “We regret to inform you that the flight has been cancelled or rescheduled.”

If you were near an airport this week, you probably saw it - the confusion, the long queues, and hundreds of frustrated travellers refreshing their mobile apps every few minutes. IndiGo, usually known for its punctuality, found itself at the centre of a nationwide meltdown. What began as minor delays quickly spiralled into a full-blown operational crisis.

So, what triggered this nationwide disruption?

Across India, IndiGo’s operations collapsed into four days of cancellations and delays, leaving passengers stranded, frustrated, and completely confused. On December 5, over 400 flights were cancelled, and at major metro airports, the airline’s on-time performance fell to just 8.5% - a dramatic fall for the carrier known for punctuality.

So what exactly went wrong?

IndiGo pointed to a mix of issues: winter schedule adjustments, unexpected technology glitches, bad weather, airspace congestion and, most importantly, the implementation of new Flight Duty Time Limitations (FDTL), the stricter pilot rest and duty hour rules introduced to combat fatigue.

But the truth is, this crisis didn’t appear overnight. It was weeks in the making.

From November 1, the final phase of the new FDTL norms kicked in, especially those restricting night operations. Pilots already stretched to the limit of 13-hour duty days began pushing back. There were long-standing grievances about no salary hikes despite record profits, denied leave requests, and mounting exhaustion. The trust deficit was widening, and when IndiGo attempted to make aggressive schedule adjustments, pilots refused to cooperate.

This triggered a chain reaction: staffing shortages, mismanaged rosters, miscalculations, and ultimately, a nationwide collapse of schedules.

By Thursday, IndiGo executives met the Civil Aviation Minister and DGCA, admitting there were “planning gaps and misjudgements.” The airline is now implementing multiple layers of corrective measures to stabilise operations.

The Civil Aviation Ministry expects flight schedules to begin normalising by Saturday and fully recover within three days. IndiGo has also requested temporary relief from the new night-duty norms until February 10, something the DGCA is still reviewing.

For now, passengers across India are hoping that the worst is finally over.
