India is the world’s third-largest domestic aviation market, with fares among the cheapest on earth – and an airline industry that has lost money in most years of its existence. Kingfisher, Jet Airways and Go First all collapsed; even market leaders swing between profit and loss. The paradox – booming passenger numbers, bleeding balance sheets – is explained by the brutal economics of flying in India: razor-thin margins, dollar-denominated costs, rupee revenues, and ferocious competition. Here is how airlines actually make (and lose) money.

The two numbers that run an airline: load factor and yield

An airline’s revenue engine has two dials. Load factor – the percentage of seats filled – measures how full the planes fly; Indian carriers typically manage 85 to 92 per cent, among the highest in the world, because empty seats are pure waste on a departed flight. Yield – revenue per passenger per kilometre – measures pricing power. The tension between them is the core of airline strategy: cut fares and loads rise but yields fall; raise fares and yields rise but planes empty. Profit lives in the narrow band where high loads meet adequate yields. The industry’s shorthand, RASK (revenue per available seat kilometre) versus CASK (cost per available seat kilometre), captures it precisely: an airline makes money only when RASK exceeds CASK, and in India the gap has often been negative – sometimes by design, as carriers chase market share.

The low-cost playbook: how IndiGo cracked it

India’s most successful airline, IndiGo, runs the classic low-cost playbook with discipline:

• Single aircraft family (Airbus A320s): one pilot pool, one set of spares, one maintenance programme – massive cost simplification.
• High aircraft utilisation: quick 30-minute turnarounds keep planes earning up to 12 hours a day.
• No frills: buy-on-board food, paid seat selection, single cabin – every extra sold is high-margin ancillary revenue.
• Point-to-point routes avoiding expensive hub connections; secondary airports with lower charges where possible.
• Sale-and-leaseback: buying aircraft then selling them to lessors frees capital and books gains.

Ancillary revenue – baggage fees, seat selection, food, priority boarding – now contributes a significant share of low-cost carriers’ income at near-100 per cent margins. It is the difference between profit and loss in bad quarters.

The cost side: why India is brutal

Indian airlines face a cost structure few countries match. Aviation turbine fuel is among the world’s most heavily taxed – central excise plus state VAT, outside GST – making fuel, already 30 to 40 per cent of costs, pricier than for foreign rivals. Aircraft leases and maintenance are dollar-denominated, so every rupee depreciation directly raises costs while revenues stay in rupees. Airport charges at privatised metros are steep, and intense competition prevents passing costs to passengers – Indian fares barely cover costs on many routes. Add debt-funded expansion and the industry’s cyclicality, and you get an industry where a single shock – a fuel spike, a currency slide, a pandemic – can erase years of profits.

Post-mortems: why the famous names died

India’s aviation graveyard is instructive because each collapse had a different cause. Kingfisher (2012) died of ambition mismatched to economics — a full-service, premium positioning in a market that rewards low costs, funded by debt from its promoter’s liquor business, with an ill-advised acquisition of the low-cost Air Deccan that it then tried to run as a premium brand. Jet Airways (2019) was a well-run full-service carrier undone by a debt-fuelled fleet expansion, high cost structure and a promoter unable to recapitalise when lenders lost patience. Go First (2023) blamed faulty Pratt & Whitney engines that grounded half its fleet — a reminder that in aviation, an operational shock plus leverage equals death. The common thread: in a market with structurally thin margins, there is no cushion for strategic error.

The Air India turnaround bet

The Tata Group’s 2022 acquisition of Air India — returning the airline to the conglomerate that founded it in 1932 — is the industry’s great turnaround wager. The group merged Air India with Vistara, ordered hundreds of new aircraft, and is betting that a premium full-service product can survive where Kingfisher and Jet could not. The logic: India’s international traffic is booming, and a strong home carrier can capture the long-haul premium that Gulf and European airlines currently take. The risk: full-service economics in a low-cost-dominated domestic market, plus the monumental task of fixing decades of accumulated operational decay. Whether the bet pays off will decide whether India gets genuine competition or slides into an effective duopoly.

Consolidation and the road ahead

The market has consolidated into essentially two groups: the IndiGo behemoth with over 60 per cent domestic share, and the Tata-Air India combine rebuilding a full-service challenger, with smaller players fighting for niches. Consolidation should, in theory, restore pricing discipline and yields – duopolies are more profitable than free-for-alls. The growth drivers are real: rising incomes, the UDAN regional connectivity scheme opening new airports, and Indians’ surging propensity to fly. But profitability will always hinge on the same fundamentals: filling planes, pricing above cost, and hedging the fuel-currency double exposure. In Indian aviation, the winners are not the airlines with the best service – they are the ones with the lowest CASK.

For passengers, consolidation cuts both ways. Fewer competitors mean fewer suicidal fare wars — which is good for airline survival but means the era of below-cost fares is ending. The regulator’s challenge is keeping the market contestable: slots at congested airports like Delhi and Mumbai are the real moat, and how they are allocated decides whether a third force can ever emerge.

FAQs

Why are Indian airfares so cheap?

Intense competition on dense routes, low-cost carrier dominance, and carriers prioritising market share over margins. Fares often sit below the true cost of the seat.

What is a load factor?

The percentage of available seats actually filled with paying passengers. Above 85 per cent is healthy; below 75 per cent usually means losses.

How do airlines make money from cargo?

Belly cargo on passenger flights and dedicated freighters earn high-margin revenue – increasingly important as e-commerce drives air freight demand.

What is UDAN?

The government’s regional connectivity scheme that subsidises airlines to fly underserved routes, capping some fares while opening new airports — it has put dozens of small cities on the aviation map.
