InterGlobe Aviation, parent company of India’s largest airline IndiGo, on Tuesday appointed William Walsh as the Chief Executive Officer. Walsh (popularly known as Willie) is currently the Director General of IATA (International Air Transport Association) and was formerly CEO of British Airways and IAG (International Airlines Group, a holding company which owns Aer Lingus, British Airways, Iberia, Level and Vueling).
His tenure at IATA comes to a close on the 31st of July, 2026, and he is expected to join no later than the 3rd of August, 2026.
The announcement of a new CEO by IndiGo comes weeks after the sudden departure of Pieter Elbers. The airline’s promoter and managing director Rahul Bhatia has taken interim charge of the company’s management. The changes in top-level management came three months after operational disruptions at the airline that crippled India’s aviation sector.
Last week, IndiGo also appointed Managing Director and Chief Executive Officer of Air India Express Aloke Singh as Chief Strategy Officer.
Welcoming Walsh, Vikram Singh Mehta, IndiGo’s Chairman said, “He is an exceptional global aviation leader with a stellar track record of outstanding leadership across several airlines. His experience in managing large scale airline operations and navigating complex market dynamics make him ideally suited to strengthen and lead IndiGo for 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 fastest growing aviation markets in the world,” he added.
Rahul Bhatia, Managing Director of IndiGo, added, “He is an iconic and accomplished aviation leader and brings a rare combination of global perspective, operational expertise of having built strong customer-focused airlines, deep industry experience and a values-driven leadership, making him exceptionally suited to lead IndiGo at this pivotal cusp of growth.”
Walsh’s career highlights commence from his role as a pilot, COO and then CEO of Aer Lingus, (2000-2005); CEO of British Airways, (2005-2011); CEO of IAG (2011-2020); and since then, the Director General of IATA (International Air Transport Association).
In his new role as IndiGo’s CEO, he will be responsible for the overall management and strategic direction of the airline with a focus on transformational initiatives to strengthen the operational performance, advance the company’s network and commercial strategy while enhancing customer experience.
Commenting on his appointment, Walsh said, “The aviation landscape is evolving rapidly, and IndiGo is extremely well-positioned to be at the forefront of this change. I look forward to partnering with colleagues across the organisation to build a culture of excellence, innovation, collaboration and sustainable value for all stakeholders.”
The appointment comes in the backdrop of massive flight disruptions in December which triggered heightened government scrutiny and tarnished IndiGo’s reputation for punctuality and efficiency. On the financial front, the airline posted a Rs 2,582 crore loss in Q2FY26 and a 76% profit drop in Q3FY26. Going ahead, external challenges such as sharp rupee depreciation and a rise in oil prices are expected to weigh on performance.
IndiGo cancelled more than 5,000 flights in the first half of December 2025 due to a severe crew shortage, especially pilots, as the airline could not implement the revised Flight Duty Time Limitations (FDTL) norms. This action stranded lakhs of passengers at airports across the country, prompting the government to intervene.
Following the crisis, the Directorate General of Civil Aviation (DGCA) imposed a penalty of Rs 22.20 crore on the airline and issued show-cause notices to senior management, including Elbers. The operational disruption is reported to have resulted in a financial impact of about Rs 2,000 crore for IndiGo.
