Economist’s perspective on India’s Airport-Airline Ownership Rethink
India’s Airport-Airline Ownership Rethink
What the proposed reform would actually change, and how it is likely to play out.
This follow-up examines the economic and competition implications behind the proposed ownership reform.
The Short Version
India’s aviation market is dominated by two carriers, IndiGo and Air India, which together control about 90% of domestic passengers. The government is now weighing whether to let airport operators—chiefly the Adani Group and GMR—own airlines too, on the theory that their deep pockets could fund a real third competitor.
Our read: this is more likely to shuffle power between a few large players than to meaningfully open up the market before 2030. The idea addresses the wrong layer of the problem, the company most able to act on it—Adani—has denied wanting to, and even in the best case, a global shortage of new aircraft means no new entrant can scale quickly regardless of what India’s Cabinet decides.
1. How Concentrated Is the Market, Really?
As of June 2026, IndiGo held 66.3% of domestic traffic and Air India Group held 23.9%—a combined 90.2%. Akasa Air, at 6.4%, and SpiceJet, at 1.9%, trail far behind.
A Market That Behaves Like a Duopoly

A much smaller domestic share.Economists measure concentration with the Herfindahl-Hirschman Index, or HHI. A market above 2,500 is considered highly concentrated under standard antitrust guidelines. India’s domestic aviation market currently sits around 5,000—roughly double that threshold.
This is not a market with a mild competition problem; it behaves more like a duopoly than an open industry.
Two extra facts sharpen the picture. First, India’s competition regulator, the CCI, already has an active case against IndiGo, currently paused while it reviews a settlement offer. Second, IndiGo itself posted a loss for FY26—about ₹23.9 billion on revenue of ₹895 billion—even while dominant, because of fuel costs, currency losses and the previous December’s mass flight cancellations.
2. Why the Proposed Fix Is an Odd Tool for This Job
The dominance problem sits in the market for airline seats. The proposed remedy changes something else entirely: who is allowed to own the airports that every airline depends on for slots, gates and ground services.
Letting an airport operator also run an airline is called vertical integration—combining the infrastructure and the carrier that uses it. It can support a well-funded new entrant, but it can also encourage foreclosure: favouring the owner’s airline through slots, gates, fees or access while squeezing competitors that depend on the same airport.
Safeguards Being Discussed
These tools can work, but only with a regulator equipped to police them continuously. India’s aviation regulator has not historically operated at that level of scrutiny, which is arguably the bigger risk.
3. Could Adani Actually Afford to Run an Airline?
Financially, yes, easily. Adani’s infrastructure businesses closed FY26 at 3.3 times net debt-to-EBITDA, below its own 3.5-times ceiling, with roughly USD 5.9 billion in cash and a falling cost of debt of 7.8%, down from 9% two years earlier.

Down from 9% two years earlier.But Adani Enterprises has formally and repeatedly denied any plan to launch or buy an airline, most recently in a stock-exchange filing on 24 July 2026. That matches the group’s long-standing view that airlines are thin-margin, cash-hungry businesses that do not fit its preference for long-life infrastructure assets.
At the same time, reporting indicates that Adani has pushed the government to relax the ownership rule. Read together, this looks less like “Adani wants to fly planes” and more like “Adani wants the option available”—the freedom to buy a stake later without committing capital now.
4. The Bottleneck Nobody Can Regulate Away: Aircraft Supply
Even a fast policy win in Delhi would not produce a new airline overnight because there are not enough new aircraft to go around.

A comparable delivery challenge.Industry-Wide Queue
The estimated global backlog in production years.IndiGo and Air India already sit near the front of that queue after placing huge orders years ago. A new entrant would either wait roughly a decade for aircraft or skip the line by buying an existing airline’s fleet. That is why any real move is more likely to be a stake in a struggling carrier—SpiceJet or Akasa are the obvious candidates—than a green-field launch.
5. Is This Normal Elsewhere? Not Really
| Market | Position | Why |
|---|---|---|
| United States | Effectively barred | Most large airports are publicly owned, and federal rules stop airport revenue from flowing into an airline business. |
| European Union | Legally possible, rarely done | Strict antitrust enforcement makes sustained favouritism too legally risky to be worthwhile. |
| Parts of Asia | A few small examples | Thailand, Vietnam and Kyrgyzstan have isolated cases, but none at India’s scale. |
If India proceeds, it would be running a large-scale experiment with very little precedent to learn from in one of the world’s fastest-growing aviation markets. IATA projects 425 million additional passengers by 2044.
6. What’s Likely to Happen
Most Likely: Watered Down
The plan stalls or becomes narrower, perhaps retaining a minority ownership cap rather than removing the limit entirely.
Plausible: Strategic Stake
The reform passes with safeguards, but the result is a stake in an existing weak carrier rather than a new airline.
Risk Case: Weak Safeguards
An airport-owning airline receives favourable treatment and triggers a prolonged competition-law fight.
One more thread is worth tracking: reporting suggests Air India’s parent, Tata, may be interested in buying into airport ownership rather than the other way around. Tata denies this too, but if true, it would be a materially different and lower-risk version of vertical integration because Tata does not control airports the way Adani does.
7. What This Means Day to Day
- Treat 2026–2027 as a volatility-management window, not a new-capacity window. Real competitive relief is a 2028-plus story at the earliest.
- Watch the CCI’s IndiGo case, not only the ownership debate, for the nearer-term signal on how seriously regulators intend to act.
- Fares are already softening on their own. IndiGo’s yields fell about 5% year on year as it added capacity faster than demand grew, so a new entrant would add supply into an already-loosening market.
The Economic Reality
The proposed reform may create optionality for infrastructure groups, but it does not directly solve India’s airline-seat concentration problem. The most likely outcome is slower, narrower and more transactional than the headline suggests: minority stakes, acquisitions or strategic partnerships rather than a fully fledged new airline before 2030.
For the travel trade, the practical message is to manage concentration risk now, follow the CCI’s actions closely and treat ownership reform as a long-term structural story—not an immediate source of new capacity or cheaper fares.
