Aviation regulator Directorate General of Civil Aviation (DGCA) has directed IndiGo to reduce its scheduled flights by 5 per cent following one of the largest operational disruptions in recent years, which led to more than 5,000 cancellations, the Economic Times reported.
IndiGo, which typically operates around 2,300 flights a day, has been gradually restoring services since the meltdown. On Monday, the airline managed to run approximately 1,800 flights.
IndiGo cites “multiple factors”
Responding to DGCA’s show-cause notice, IndiGo expressed regret over the severe disruption and attributed the situation to a “confluence of multiple factors.”
According to TOI, the airline highlighted minor technical issues, winter schedule transitions, adverse weather conditions, rising airspace congestion, and complications arising from the implementation of Flight Duty Time Limitation (FDTL) Phase II norms that came into effect on November 1, 2025.
IndiGo said the scale of operations made it “realistically not possible to pinpoint the exact cause(s)” within the regulator’s deadline and sought more time to conduct a detailed root-cause analysis as per DGCA’s 15-day response rule.
Cancellations called a “drastic reboot”
The airline also defended its move on December 5, when more than 1,000 flights — nearly half its schedule — were cancelled in a single day. IndiGo termed it a “drastic measure” aimed at resetting operations, clearing stranded passengers, easing congestion at major airports, and repositioning aircraft and crew.
DGCA launches investigation panel
A four-member investigation team headed by Joint DG Sanjay Brahamane has been appointed to probe the disruption. The panel is expected to scrutinise IndiGo’s manpower planning, crew rostering, and readiness for FDTL Phase II compliance.
As per TOI, the committee may also summon IndiGo CEO Pieter Elbers and COO Isidre Porqueras.
Possible action against airline
Depending on the panel’s findings, DGCA may proportionally scale down IndiGo’s flight operations based on actual crew availability — which could free up airport slots for other carriers.
Apart from potential monetary penalties, disciplinary action could also be initiated against top executives, including the COO. IndiGo may consider internal restructuring, including resignations or terminations, if key personnel are found responsible for the operational collapse.
