One Staffing Error. Hundreds of Flights Grounded. IndiGo’s Toughest Week Yet

IndiGo is now at the centre of a nationwide travel disruption, with hundreds of flights cancelled or delayed across India. On some days, over 550 flights were grounded nationwide. On 4 December alone, airports in Delhi, Bengaluru, Mumbai and Hyderabad recorded major cancellations.

The root cause is the new pilot duty-time rules introduced by DGCA under its revised Flight Duty Time Limitation (FDTL) norms, which came into full effect on 1 November 2025. These rules raised required rest periods for pilots, reduced the allowed night-flying and night-landing windows, and limited total duty hours. Because IndiGo did not have enough crew on standby to meet these requirements, many flights could not operate safely or legally.

Passengers faced long waiting times, baggage delays, crowded terminals, and widespread frustration. In November 2025, IndiGo cancelled about 1,232 flights. Its on-time performance dropped to 67.7 %  in November from 84.1 % in October. On 3 December, reports show on-time performance fell as low as 19.7 %. As operations spiralled, the regulator granted IndiGo temporary relief: a one-time exemption from certain night-duty restrictions for its A320 fleet, valid until 10 February 2026.

IndiGo posted an apology on X, promising refunds for cancelled flights.

Week IndiGo’s Schedule Fell Apart

At the heart of this disruption is a failure in workforce planning, rostering, and scheduling, which fall under human resources and operations teams. The DGCA first signalled the FDTL revisions many months ago. The first phase of the norms went live in July, and full enforcement began 1 November. Despite this, IndiGo did not strengthen its pilot pool or build in enough reserve crew to meet the new rest and duty requirements.

For its A320 fleet, the airline now reports a crew strength that falls short of what the norms demand. The lean staffing strategy without buffer crew meant that when the rules came into effect, there was no flexibility. Crew shortages combined with limited night-flying slots per pilot quickly triggered widespread cancellations.

Decisions about pilot staffing, rostering, and duty allocation were not treated as core business priorities. HR and manpower planning did not get the focus needed for a safety-critical, regulated industry like aviation. The airline appears to have assumed that its existing crew would be sufficient without considering how much the new rules would change scheduling requirements.

Planning Miss That Derailed Operations

IndiGo is reorganising pilot and crew schedules and increasing standby staff to meet the requirements of the revised FDTL rules. The airline is processing automatic refunds and allowing passengers to reschedule flights without any charges. 

The DGCA granted a temporary exemption from certain night-duty restrictions for the airline’s A320 fleet until 10 February 2026. This provides time for IndiGo to adjust crew rosters while continuing operations. Airport teams are handling passenger flows, baggage, and boarding support to manage disruptions.

The incident shows the operational impact when workforce planning and crew rostering do not align with regulatory requirements. IndiGo is monitoring flight schedules closely and providing regular updates to passengers as services gradually stabilise. The airline expects normal operations to return by early February 2026.
