India’s largest airline, IndiGo, has reported a narrower loss for the September quarter, but the numbers show just how hard rising fuel costs are hitting Indian aviation. InterGlobe Aviation, the airline’s parent company, posted a consolidated net loss of ₹1,879.1 crore for the quarter ended September 30, 2026, down from ₹2,582.1 crore in the same quarter a year earlier. Revenue, however, grew strongly — and that contrast is the story of the quarter.
Consolidated revenue from operations rose 25.9% year on year to ₹23,363.8 crore, up from ₹18,555.3 crore in the year-ago quarter. Total income reached ₹24,311.9 crore, against ₹19,599.5 crore a year earlier. On a standalone basis, the net loss was ₹2,055.2 crore, compared with ₹2,614.1 crore in the corresponding quarter last year.
Key Takeaways
- IndiGo’s consolidated net loss narrowed to ₹1,879.1 crore in the September quarter, from ₹2,582.1 crore a year earlier.
- Revenue from operations rose 26% to ₹23,363.8 crore, but aircraft fuel expenses surged 67.2% to nearly ₹9,967 crore.
- The airline recovered only about 60% of the fuel-cost increase through higher fares and surcharges, and warned fares may have to rise further.
Why the Loss Narrowed but Did Not Disappear
The September quarter is traditionally a soft period for Indian airlines, falling between the summer holiday season and festive travel. This year, that seasonal weakness collided with what chief executive Willie Walsh described as exceptionally elevated fuel costs and continued geopolitical turmoil. “The seasonally soft September quarter saw exceptionally elevated fuel costs and continued geopolitical turmoil,” Walsh said on a post-earnings analyst call. “We responded with prudent capacity reduction and yield management, supporting strong revenue performance but only partially offsetting the higher costs.”
The seasonally soft September quarter saw exceptionally elevated fuel costs and continued geopolitical turmoil.
The fuel bill is the clearest pressure point. Aircraft fuel expenses surged 67.2% year on year to ₹9,966.8 crore, up from ₹5,961.8 crore in the year-ago quarter. Jet fuel was priced at ₹137 per litre in October for domestic flights, 46% more than a year earlier, according to the Economic Times report on the results. The airline said it recovered only about 60% of the fuel-cost increase through higher fares and other measures, leaving a large share of the increase absorbed by the carrier itself.
Currency weakness added to the strain. IndiGo reported a foreign exchange loss of ₹1,333.2 crore in the quarter, alongside depreciation and amortisation charges of ₹3,074.2 crore and finance costs of ₹1,657.8 crore. Between 50% and 60% of its non-fuel costs are dollar-denominated, Walsh noted, leaving the airline clearly exposed to depreciation against the dollar. That exposure matters because fuel, aircraft leases and maintenance are also heavily dollar-linked, so a weaker rupee raises costs on several fronts at once.
Fewer Passengers, Higher Fares
Passenger numbers also slipped. Capacity, measured in available seat kilometres, was reduced by 1% to 40.8 billion, while the number of passengers flown decreased by 4.7% to 27.5 million. Aviation experts attributed the decline to high fares amid rising fuel costs, and one reported example showed the average one-way fare between Calcutta and Bagdogra more than doubling, from ₹3,500 to over ₹7,000, according to airline sources cited in the Telegraph report.
That fare pressure sits inside a wider energy and market picture. Crude prices have been running near six-month highs on supply fears linked to attacks in the Middle East, and shipping through the Strait of Hormuz has faced fresh disruption, both of which feed into the jet-fuel premium airlines pay over crude. Walsh said the crack spread — the premium jet fuel commands over crude — had risen sharply, averaging far above its historical level this year. For travellers, the practical result is straightforward: when fuel stays expensive, ticket prices tend to follow.
- Consolidated net loss: ₹1,879.1 crore, narrowed from ₹2,582.1 crore a year earlier.
- Revenue from operations: ₹23,363.8 crore, up 25.9% year on year.
- Aircraft fuel expenses: ₹9,966.8 crore, up 67.2% year on year.
- Foreign exchange loss: ₹1,333.2 crore in the quarter.
- Passengers flown: 27.5 million, down 4.7% year on year.
- Capacity: 40.8 billion available seat kilometres, down 1%.
What IndiGo Is Doing About Costs
IndiGo has moved on several fronts to protect its margins. It cut capacity in the September quarter, raised fuel charges on domestic and international routes in October after a similar move in April, and said it would evaluate fuel-price hedging, although it has yet to announce a formal programme. It also withdrew its wet-leased widebody operations on international routes from October 25 as part of a strategy to optimise operating costs.
For the December quarter, IndiGo guided for low single-digit capacity growth in available seat kilometres, with strong ticket prices expected to boost passenger revenue by more than 25%. The December quarter is traditionally stronger because of festive travel, and Walsh said he remained optimistic about long-term growth opportunities. Liquidity also remains a cushion: the airline reported free cash of around ₹399 billion, which Walsh said positions it to navigate near-term volatility while retaining flexibility to invest in long-term priorities.
The wider industry backdrop is tougher. According to ICRA figures cited in coverage of the results, domestic air passenger traffic fell 6.5% year on year to 118.2 lakh in September 2026, and domestic traffic in the first half of fiscal year 2027 fell 1.9%. ICRA has a negative outlook on the Indian aviation industry, citing higher fuel costs, a weaker rupee and international airspace disruptions, and estimates Indian airlines could post combined net losses of ₹36,000–38,000 crore in fiscal year 2027. Against that backdrop, IndiGo’s narrowing loss looks like relative resilience rather than a recovery — a point reflected in the broader market mood, where Indian benchmarks rallied strongly on Thursday even as aviation costs stayed in focus.
What to Watch Next
What to watch next is only what this report has already set out: whether fuel costs ease or stay elevated into the December quarter, whether IndiGo’s low single-digit capacity growth and stronger festive-season fares lift passenger revenue by more than 25% as guided, whether the airline formalises a fuel-hedging programme, and whether passenger numbers recover from the 4.7% decline seen in the September quarter. The other test is the wider industry picture — whether domestic traffic stabilises after the September fall, and whether the combined losses ICRA estimates for fiscal year 2027 materialise. Until fuel and currency pressures ease, the September quarter’s message stands: revenue can grow strongly and the airline can still lose money.
