IndiGo's schedule collapse grounded thousands — and then the CEO resigned

In December 2025, IndiGo, India's largest airline, suffered an unprecedented operational collapse. A failure to properly plan for pilot rest and scheduling requirements forced the cancellation of thousands of flights, stranding tens of thousands of passengers. The crisis drew intense scrutiny from India's aviation regulator, the Directorate General of Civil Aviation (DGCA), and severely damaged the airline's reputation for reliability.

Three months later, on March 10, 2026, CEO Pieter Elbers resigned with immediate effect, citing personal reasons. Elbers had joined IndiGo in 2022 from KLM and was credited with steering the airline through the post-pandemic recovery. However, the December 2025 scheduling crisis had exposed weaknesses in the airline's operational planning that had not been addressed under his leadership. Managing Director Rahul Bhatia took interim charge.

The collapse was a reminder that IndiGo's aggressive growth strategy — expanding its fleet and route network faster than most competitors — had outpaced its operational infrastructure. The airline had prioritised capacity over the systems needed to manage that capacity, and the pilot scheduling system was the first to break.
