IndiGo on Tuesday appointed William Walsh, the former chief executive of British Airways and current head of the International Air Transport Association (IATA), as its chief executive – closing a leadership gap that opened three weeks ago when Peter Elbers resigned in the wake of the worst operational crisis in the airline’s history late last year.
Walsh, who is expected to join no later than August 3 after his tenure at IATA ends on July 31, brings to IndiGo a career that spans the cockpit and the boardroom. Starting out as a pilot, he rose to lead Ireland’s Aer Lingus, then served as CEO of British Airways from 2005 to 2011, before spending nearly a decade as CEO of International Airlines Group – the holding company that owns British Airways, Iberia, Aer Lingus and Vueling – making him one of the architects of the unification of modern European aviation. His appointment is subject to regulatory approvals.

“I am thrilled to have the opportunity to lead IndiGo,” Walsh said in a statement from the airline. “What stands out to me most is its people, their passion, professionalism and commitment.”
The appointment comes at a risky moment for India’s largest airline. In December 2025, IndiGo canceled at least 5,500 flights over the course of about a week after failing to implement revised flight time limitation norms — rules governing mandatory rest periods for pilots and crew — despite having nearly two years to prepare. This disruption stranded hundreds of thousands of passengers during the peak travel season and led to a highly severe regulatory response. The Directorate General of Civil Aviation imposed a standard penalty of more than $22 crore, ordered a 10% reduction in IndiGo’s winter schedule, and directed the airline to save $Bank guarantee of Rs 50 crore linked to interim operational repairs. Show notices were issued to Elbers personally, as well as to the chief operating officer. A senior vice president has been removed from his position on the orders of the regulatory body.

Elbers resigned on March 10 — 18 months before his contract expires in September 2027 — citing personal reasons in his letter to the board. But a person familiar with the matter told HT that the resignation is linked to the findings of the airline’s internal investigation, which also sought help from independent experts. The source, who requested to remain anonymous, said: “It appears that the resignation is the result of the airline’s investigations.”
IndiGo co-founder and managing director Rahul Bhatia took over as interim CEO and said on Tuesday: “As we enter a new phase of transformation and growth, I am thrilled to welcome Willie to IndiGo. He is an accomplished and accomplished aviation leader who brings a rare combination of global perspective, operational experience of building strong, customer-focused airlines, deep industry expertise and values-based leadership, making him exceptionally suited to lead IndiGo at this pivotal stage of growth.”

Vikram Singh Mehta, Chairman of IndiGo, said: “I am delighted to have Willie at the helm of IndiGo. He is an exceptional global airline leader with a proven track record of outstanding leadership across multiple airlines. His experience managing large-scale airline operations and navigating complex market dynamics make him ideally suited to enhance and lead IndiGo to achieve continued growth in an ever-evolving and competitive international aviation environment. His appointment will mark a new chapter for IndiGo, as it continues its journey in one of the world’s fastest growing aviation markets.”
Under Elbers’ management, IndiGo’s fleet grew from 302 to 440 aircraft, its network expanded from 97 to 140 destinations, the airline placed its first order for widebody aircraft and launched a business class product. However, the company’s net profits in the third quarter of fiscal year 2026 fell by 77.6% year-on-year to $549.8 crore, reflecting the combined impact of the December idling, Pratt & Whitney engine shutdown and higher costs.
