(INDIA) — IndiGo said Pieter Elbers resigned as chief executive with immediate effect on March 10, 2026, citing personal reasons, nearly three months after the carrier’s December 2025 flight cancellation crisis.

Rahul Bhatia, IndiGo’s founder and managing director, assumed interim management, the airline said in a regulatory filing to the Bombay Stock Exchange on March 10.

Elbers, who joined as CEO in September 2022, asked for his notice period to be waived and said he felt honored to have served the airline.

The resignation lands as IndiGo continues to deal with fallout from a disruption that began on December 2, 2025 and spread across its network for days, stranding large numbers of passengers and drawing scrutiny from regulators.

Cancellations peaked with over 1,000 flights canceled on December 5 alone, before the airline logged nearly 4,500 cancellations over ten days. At least 300,000 passengers were affected, according to the account of the episode.

Major airports absorbed the shock, including Delhi, Mumbai, Bengaluru, Hyderabad, and Chennai, as on-time performance dropped to as low as 8.5% at some hubs. In Delhi, all domestic IndiGo departures were grounded until midnight on December 5.

IndiGo attributed the breakdown to operational factors that compounded quickly once schedules started slipping, including a failure to adapt to new DGCA Flight Duty Time Limitations (FDTL) norms on pilot rest.

Pressure built because the airline had over-optimized crew and aircraft and carried inadequate buffers, leaving only 4% of crew for contingencies. Weak software and management oversight gaps added to the problems as the disruption spread.

Elbers publicly apologized on X on December 5 and projected stabilization by December 10-15, 2025, with full normalcy by February 10, 2026. IndiGo waived fees for changes and cancellations through December 15 and provided meals, hotels, and refunds.

Government action also played a role in the immediate response, with authorities temporarily relaxing night duty rules. Pilot unions criticized that move.

Regulators later moved from response to enforcement as they examined how IndiGo planned rosters and managed the transition to the new duty-time regime.

A DGCA four-member committee, directed by the Ministry of Civil Aviation (MoCA), identified over-optimization and poor FDTL implementation as the primary causes. The panel’s conclusions put the airline’s planning choices at the center of the crisis narrative.

On January 17, 2026, DGCA fined IndiGo 222 million rupees ($2.45 million) for roster planning lapses and failure to balance commercial goals with crew capacity. The action added formal weight to the argument that systems and staffing decisions, not a single disruption, drove the cascade.

IndiGo also commissioned Chief Aviation Advisors for a root cause review led by Captain John Illson, as it sought an external assessment of what went wrong and how to prevent a repeat.

Management changes followed inside the operations chain. On February 20, 2026, Captain Rohit Rikhye replaced Jason Herter as head of operations control.

Bhatia, recovering from surgery in Switzerland at the time, criticized the December events in an internal email and wrote: “What happened last December should never have taken place.”

Financial pressure mounted alongside the operational and regulatory aftershocks, with losses reaching Rs 2,000 crore, per NDTV Profit sources. The airline remained the dominant player in the domestic market, holding over 60% domestic market share.

Elbers’ departure, announced without delay and framed around personal reasons, has been widely viewed as linked to the crisis fallout. That view has persisted as scrutiny continues, including a Competition Commission of India probe, keeping attention on governance and operational practices at a carrier central to India’s air-travel system.
