Most airlines that start flying long-haul get caught up in it. New routes, new cabins and new aircraft types tend to pull money and management attention away from the business that made them successful. On Tuesday, IndiGo's new chief executive made it clear he wants to avoid that.

Speaking at the Aviation India and South Asia 2026 conference in New Delhi, Willie Walsh said IndiGo will keep its core short-haul business as the priority even as it speeds up its international expansion. His point was simple: the airline's global plans should not distract from the domestic and regional network that supports its low-cost model.

"We must ensure we do not lose focus on the work required to maintain a highly efficient short-haul operation while preparing for future opportunities," Walsh said.

Two fleets, one discipline

The numbers show how IndiGo is handling the change. The airline currently operates four A321XLRs, narrow-body jets with extra range that let it serve longer international routes without leaving the single-aisle model it knows well. IndiGo expects 14 of these aircraft to be flying by the end of 2027.

The bigger step comes later. Walsh said IndiGo is preparing to induct Airbus A350-900 wide-body aircraft, with deliveries expected to begin from the second quarter of 2028. He also admitted that a lot of groundwork is needed before services on the new type can start. That covers the less visible work of crew training, maintenance capability and network planning.

For an airline built on running one aircraft family very efficiently, adding a wide-body type is a big operational change. Walsh's warning suggests IndiGo plans to grow into it slowly rather than rush it.

Cost as the competitive moat

Walsh described IndiGo's cost structure as one of its key competitive strengths and said it will continue to support the airline's growth plans. In a price-sensitive market like India, that cost advantage helps IndiGo keep fares competitive and stay profitable.

That is also why he spoke directly to airport operators. Walsh called for closer collaboration between airlines and airports and asked operators to stay disciplined in their investment decisions so that excessive financial burdens do not fall on carriers and passengers. This is a familiar concern for airlines, because airport charges eventually show up in ticket prices.

Why it matters

The stakes are large. As India's largest airline by market share, IndiGo operates more than 440 aircraft and plans to reach around 600 by 2030. How it balances short-haul efficiency against long-haul ambition will affect fares, connectivity and competition across Indian aviation.

The comments also give an early look at Walsh's leadership style. He took charge earlier this year after being appointed by parent company InterGlobe Aviation, following the departure of former CEO Pieter Elbers, under whom the airline expanded rapidly in both domestic and international markets. Elbers' era was defined by growth. Walsh is signalling that the next phase will be about disciplined growth.

The road ahead

As more long-range aircraft join the fleet over the next few years, IndiGo is expected to widen its global footprint. Walsh's message is that the short-haul network will remain the foundation of that growth.
