Why it might be difficult to break IndiGo’s dominance for the next few years

After a rather challenging 2025, when it struggled with unprecedented flight cancellations, IndiGo—India’s largest airline by market share—is busy charting plans to flex its dominance in the Indian skies.

The company has already roped in Willie Walsh, an airline veteran and the former head of British Airways, to steer the company after Pieter Elbers, the India-loving former CEO of IndiGo, left in the aftermath of the cancellation fiasco. Now, ahead of his arrival, the airline has given a glimpse into how it intends to shape itself under Walsh.

First and foremost, among those, in a presentation to analysts, IndiGo states that it will grow its international capacity to 40%, with mid- and long-haul operations increasing to 10-15% from about 4% currently. These will be operated by the airline’s Airbus A321 XLR and A350 aircraft.

Earlier this year, IndiGo had inducted the first of its 40 A321 XLR aircraft and has an order book of 60 A350-900 aircraft. The Airbus A321 XLR can fly up to 4,700 NM (8,000 miles) with a maximum seating capacity of 244 passengers, helping IndiGo expand its operations from nearby South Asia to longer routes, including the UK and Europe.

The Airbus A350-900 has a maximum flight range of 8,500 nautical miles (over 15,750 miles), carries over 400 passengers, and enables the airline to even fly as far as the US. That’s a significant leap considering how IndiGo’s international available seat kilometres (ASKM), which is a measure of an airline's total passenger-carrying capacity, has increased from 16% in FY16 to 32% in FY26.

 From 5 destinations and 12 routes in FY16, the international network has expanded to 44 destinations and over 150 routes in FY26. In all, the Rahul Bhatia-controlled airline plans to operate a fleet of over 550 aircraft, carry 200 million passengers annually, and run roughly 3,000 flights a day by financial year 2030.

That’s not all. For an airline widely acknowledged for its sale-and-leaseback model, IndiGo is also planning to increase the proportion of owned aircraft in its fleet to 30-40% from about 20% currently. In a sale-and-leaseback model, an airline acquires the aircraft and sells them to a lessor before leasing them back for use. The sale is usually profitable and helps with cash. As of FY26, 75% of the fleet was under operating lease, 12% under finance lease, 8% owned, and 5% under damp lease arrangements.

“Indigo’s competitive advantage continues to be underpinned by its industry-leading cost structure, operational excellence and unmatched network scale, particularly across underserved metro to non-metro and non-metro to non-metro markets, where nearly one-third of the network faces limited direct competition,” brokerage firm Emkay says in a report. “Indigo maintains its strategy of focus on preserving its LCC structure— among the most competitive globally—and expanding into long-haul international markets as well as adjacent opportunities via selective premiumization.”

Then, there is also the focus on the premium offering. For an airline long acknowledged for its tight leash on costs, IndiGo has been busy pioneering a hybrid airline model and has also begun focusing on premium offerings. The airline already offers a frequent-flyer programme in addition to its own version of business-class seats, commonly known as IndiGo Stretch.

IndiGo is now planning to offer its Stretch seats to 105 aircraft by FY27-end, up from 53 aircraft at present. That means the airline will quickly ramp up from about 2,700 business-class seats per day to 4,300 by the end of the current fiscal year.

Already, the airline’s loyalty programme, BluChip, has crossed 11 million members within 20 months of launch, with IndiGo now expanding it through partnerships across financial services, retail and lifestyle categories. The airline reckons that its loyalty programme users are 20% more likely to upgrade seats, reinforcing its premiumisation strategy.

The move to premiumise and offer a hybrid model puts it in direct competition with Air India in India’s duopolistic airline market. Air India itself has been in the midst of a $75 billion makeover, with changes including revamped cabins and the in-flight experience, as well as new aircraft and crew. Together, Air India and IndiGo have as many as 1,000 aircraft on order to cater to the growing demand in the world’s third-largest aviation market.

“Barring near-term aberrations, the long-term capacity guidance is quite encouraging, largely led by plans to expand presence in international markets,” brokerage firm Prabhudas Liladhar said in a note. “Nonetheless, we believe pick-up in growth is largely back-ended and near-term challenges continue to prevail.”

Now, all eyes will be on Willie Walsh, the incoming CEO, who will take charge in less than two months, with the mandate to ensure that the airline returns to its ruthless best, especially since it looks to expand its international operations.

“Mr. Walsh is widely considered one of the most successful, respected, influential, and long-lasting leaders in modern aviation history,” IndiGo had said in the statement at the time of announcing Walsh’s appointment. “He is admired for his pragmatic and resolute management, effective complex restructuring, and successful mergers and acquisitions.
