IndiGo's CEO Willie Walsh plans to boost revenue per passenger through premium seating, paid extras, and loyalty programs while maintaining the airline's low-cost model that has made it India's largest carrier.

Walsh outlined the strategy on the airline's earnings call, identifying three growth areas: premium cabins, ancillary revenues per passenger, and a longer-term loyalty program. Co-founder Rahul Bhatia confirmed in May that IndiGo's low-cost, single-aisle core will remain unchanged after former CEO Pieter Elbers' departure.

The revenue push comes as IndiGo faces mounting cost pressures. Revenue grew 26% in the September quarter, but fuel costs jumped 67%, resulting in a net loss of approximately INR 18.8 billion ($197 million). This loss narrowed from INR 25.8 billion ($271 million) a year prior.

Walsh acknowledged that India's regulatory rules limit how far IndiGo can replicate the Ryanair model of ancillary revenue generation that depends on European regulatory frameworks.
