The Directorate General of Civil Aviation (DGCA) has taken stringent regulatory action against IndiGo Airlines following widespread flight disruptions in early December 2025 that caused chaos across airports nationwide and left lakhs of passengers stranded. After a detailed inquiry, the aviation watchdog imposed a penalty of Rs 22.20 crore on the country’s largest airline and issued formal warnings to its top management, including CEO Pieter Elbers.
In addition to the monetary fine, the DGCA has directed IndiGo to furnish a bank guarantee of ₹50 crore in its favour. The move, the regulator said, is aimed at ensuring strict compliance with regulatory directives and enforcing long-term systemic corrections within the airline’s operations.
According to the DGCA, between December 3 and December 5, 2025, at least 2,507 IndiGo flights were cancelled and another 1,852 flights were delayed. The disruption affected nearly three lakh passengers across multiple airports, triggering widespread complaints, overcrowding at terminals, and intense scrutiny of the airline’s operational preparedness.
In response to the crisis, the DGCA constituted a four-member high-level committee to conduct a comprehensive assessment of the circumstances that led to what it described as a serious operational failure.
Following an in-depth examination of IndiGo’s network planning, crew rostering systems, operational software, and management processes, the committee identified multiple structural and managerial shortcomings.
The primary causes of the meltdown, the DGCA said, included excessive over-optimisation of operations, inadequate regulatory preparedness, deficiencies in system software support, and weaknesses in management structure and operational control.
The committee observed that IndiGo failed to adequately identify planning gaps, maintain sufficient operational buffers, or effectively implement the revised Flight Duty Time Limitation (FDTL) provisions. These lapses, it noted, directly contributed to cascading delays and mass cancellations.
A key concern highlighted in the report was the airline’s overriding focus on maximising utilisation of aircraft, crew, and network resources. While aimed at efficiency, this approach significantly reduced buffer margins in crew rostering and compromised roster integrity, severely undermining operational resilience during periods of stress.
Apart from the financial penalty, the DGCA issued a formal caution to IndiGo CEO Pieter Elbers for what it termed inadequate overall oversight of flight operations and crisis management during the disruption period.
A warning was also issued to the airline’s Accountable Manager and Chief Operating Officer (COO) for failing to properly assess the operational impact of the revised FDTL rules. The Senior Vice President of the Operations Control Centre (OCC) was directed to be relieved of current operational responsibilities and barred from holding any accountable position, citing failure in systemic planning and timely implementation of regulatory provisions.
Warnings were further issued to other senior officials for lapses in operational supervision, manpower planning, and roster management.
Despite the sharp criticism, the DGCA acknowledged that IndiGo’s recovery from the crisis was “remarkably swift”. The regulator noted that the airline managed to restore its operations to near-normal levels within a short span, limiting prolonged disruption.
Responding to the DGCA order, IndiGo chairman and the Board of Directors of InterGlobe Aviation Limited issued a statement acknowledging the findings and assuring corrective action.
“We would like to take this opportunity to inform all our stakeholders, particularly our valued customers, that the Board and the Management of IndiGo are committed to taking full cognisance of the orders and will, in a thoughtful and timely manner, take appropriate measures,” the statement said.
The airline further stated that an in-depth review of the robustness and resilience of its internal processes has been underway since the disruption. “This is to ensure that IndiGo emerges stronger out of these events in its otherwise pristine record of over 19 years of operations,” the statement added.
Reiterating its long-term vision, IndiGo said it remains committed to serving the needs of India and contributing to the country’s ambition of emerging as a global aviation hub by 2030.
