Adani Group's Denial Doesn't Resolve Competition Law Risks of Airport-Airline Cross-Ownership Loopholes

The Ministry of Civil Aviation’s proposal to relax cross-ownership restrictions between airport operators and airlines has sparked a critical debate on competition law in India’s aviation sector. While the Adani Group has publicly denied any immediate plans to enter the airline business, legal experts warn that the policy change, if implemented without robust safeguards, could enable anti-competitive structures that harm consumers and stifle competition. The issue exposes significant gaps in the existing regulatory framework, where ownership caps are contractual rather than statutory, and where the Competition Commission of India (CCI) may lack ex-ante oversight over precisely the transactions that pose the greatest risk.

At present, concession agreements governing Delhi and Mumbai airports cap cross-ownership at 10%, while the newer Noida International Airport (Jewar) and Navi Mumbai Airport allow up to 26%. The Ministry is reportedly considering further liberalisation, a move that some reports linked to the Adani Group’s interest in launching an airline—a claim the conglomerate has called “baseless.” Yet, as the opinion piece notes, “a firm's present intention is a fact about today and not a seal for years to come.” The Adani Group already controls eight of India’s 30 operational airports, handling roughly a quarter of national air traffic, along with stakes in ground handling, maintenance, repair and overhaul (MRO), and pilot training. Such vertical integration, even without an airline, raises competition concerns under the Competition Act, 2002.

The Competition Act’s Reach—and Its Limits

The Competition Act provides tools to address potential abuse, but they are far from automatic. Section 4(2)(e) prohibits an enterprise from using its dominance in one market to enter or protect its position in another—exactly the risk when an airport operator that controls slots, gates, and check-in counters also owns a carrier competing for those same resources. Similarly, Section 4(2)(c) bars conduct that denies market access, and the factors under Section 19(3) for assessing appreciable adverse effect on competitionentry barriers, foreclosure of competitors, and consumer harm—mirror the warnings voiced by IndiGo and Air India.

However, these protections only kick in after “dominance” is established and “abuse” is proven, a process that can drag on for years before the CCI or appellate tribunals. In a capital-starved, slot-constrained industry, a carrier squeezed out of prime Delhi or Mumbai timings may not survive long enough to be vindicated. The ex-ante combination control regime under Sections 5, 6, and 20 also has limitations: an airport operator taking a modest stake in a new airline, or simply floating a fresh carrier, may never trigger a notifiable combination if the asset or turnover thresholds are not crossed. This leaves the CCI blind to precisely the transactions at issue.

The Essential Facilities Doctrine: An Underdeveloped Tool

Slots, gates, and terminal counters are near-textbook examples of “essential facilities”—infrastructure a rival cannot replicate or route around. The CCI has gestured at this doctrine in the Arshiya Rail Infrastructure v. CONCOR matter and in Turbo Aviation’s complaint against Bangalore International Airport, but it has never affirmatively imposed a duty to deal, unlike the European Court of Justice in Bronner . Indian jurisprudence on refusal to deal in infrastructure remains underdeveloped, and a relaxation of cross-ownership caps would test this gap immediately. As the source warns, “a carrier squeezed out of prime Delhi or Mumbai timings may not survive long enough to be eventually vindicated by a CCI order.”

A Regulatory Void

The deeper problem is that the 10% and 26% caps are not statutory limits but clauses in concession agreements between the government and individual operators. The Airports Economic Regulatory Authority (AERA), established in 2008, regulates aeronautical tariffs and service quality but has no explicit mandate over ownership structures. The Directorate General of Civil Aviation (DGCA) licenses aircraft and airlines but does not police market structure. Cross-ownership thus sits in a regulatory void, subject to executive amendment to a contract, outside the CCI’s ex-ante gaze unless a threshold is crossed, and outside AERA’s tariff-focused remit altogether. A sector defined by scarce, non-substitutable infrastructure and entry barriers is governed by three regulators, none of which holds a standing veto grounded in competition principles.

A Workable Fix

The opinion piece proposes several practical remedies: moving ownership ceilings out of individual concession contracts and into a binding regulation under the Airports Economic Regulatory Authority of India Act, 2008, so they cannot be diluted concession by concession through closed-door renegotiation; mandating CCI notification of any airport operator stake in an airline and vice versa, irrespective of asset or turnover thresholds, under the pre-merger clearance model already used in banking and insurance; and establishing a standing information-sharing arrangement between the CCI and AERA, similar to the MoUs used by the Securities and Exchange Board of India with other sectoral regulators, paired with a mandatory two-year competition-impact review before any relaxation is made permanent.

Conclusion

“Competition law does not exist to police what a company says it intends to do; it exists to police the structures that make ‘abuse’ possible, regardless of intent,” the source concludes. Whether or not any conglomerate ever enters the airline business, unwinding decades-old separation between airport and airline without first building the machinery to watch it would leave Indian aviation more concentrated and Indian competition law exposed exactly where it claims to be strongest. The legal community must press for structural safeguards before any relaxation takes effect, ensuring that competition principles are not left to the vagaries of executive contract amendments or delayed litigation.
