India’s aviation regulator has imposed a record fine of $2.45 million on IndiGo, issued warnings to top executives and ordered the removal of a senior operations official after widespread flight cancellations last month exposed serious weaknesses at the country’s largest airline. The action follows the scrapping of around 4,500 flights in early December, an episode that disrupted travel for tens of thousands of passengers across the country and intensified scrutiny of competition and resilience in India’s booming aviation sector.
The Directorate General of Civil Aviation said its investigation found multiple deficiencies in IndiGo’s operational planning after stricter pilot duty and rest rules came into force last year. IndiGo, which controls roughly 65% of India’s domestic aviation market, acknowledged that poor pilot roster planning was the main cause of the cancellations. Regulators concluded that the airline failed to identify planning gaps or maintain sufficient buffers to absorb operational shocks.
In a sharply worded statement, the DGCA said IndiGo had placed an “overriding focus” on maximising the use of pilots, aircraft and network resources, a strategy that ultimately weakened its ability to cope with disruptions. The regulator said this approach compromised roster integrity and damaged operational resilience, leading to cascading cancellations once the system came under strain.
Alongside the fine, which a government source said was the largest ever imposed by the authority, the DGCA issued warnings to several senior executives. Chief Operating Officer Isidre Porqueras and Jason Herter, senior vice president of the airline’s operations control centre, were formally cautioned, with the regulator directing IndiGo to immediately relieve Herter of his operational duties. Chief executive Pieter Elbers received a separate caution for what the DGCA described as inadequate overall oversight of flight operations and crisis management.
The financial penalty, while record-breaking, represents a small fraction of IndiGo’s earnings, amounting to about 0.31% of its annual profit for the 2024/25 fiscal year. In addition, the airline was ordered to provide a $5.51 million bank guarantee in favour of the regulator to ensure compliance with its directives and to support what the DGCA called long-term systemic correction.
IndiGo said its board and management were committed to fully recognising the regulator’s orders and would take appropriate measures in a timely and considered manner. The airline has faced mounting pressure from passengers, unions and policymakers after the December chaos raised concerns about the risks of heavy market concentration in a sector that has grown rapidly over the past decade.
The fallout has also drawn attention to the regulator itself. The DGCA said the aviation ministry had ordered an internal inquiry into the authority’s own functioning, suggesting official concern over whether warning signs were missed ahead of the disruptions. In the immediate aftermath of the cancellations, the government temporarily relaxed some rules on night duties for pilots to help stabilise IndiGo’s operations, a decision that drew criticism from pilot unions and aviation safety advocates.
Separately, India’s competition regulator is reviewing allegations of antitrust violations involving the two-decade-old airline, adding another layer of regulatory pressure. Together, the investigations and penalties mark one of the most serious challenges IndiGo has faced, as authorities seek to reinforce safety, accountability and competition in the world’s fastest-growing aviation market.
