Airports in India are increasingly becoming commercialised and transforming into full-fledged economic ecosystems. Relying solely on aeronautical revenue is proving to be a weak business model. Operators are therefore expanding the airport ecosystem to include retail, food and beverages (F&B), advertising, mobility, data, real estate and loyalty programmes. The aim is to diversify cash flows, reduce risks on capex cycles and increase funding opportunities.
According to ACI World, non-aeronautical activities accounted for roughly 36.7 per cent of total airport revenues in 2023. Globally, airports such as Singapore’s Changi and Seoul’s Incheon demonstrate how airports can transform into attractive destinations by integrating entertainment zones, cultural exhibitions, wellness facilities and co-working spaces. Moreover, as per the Airport Service Quality Survey, a 1 per cent rise in global passenger satisfaction leads to an average 1.5 per cent growth in non-aeronautical revenue (NAR).
Growing NAR focus
In India, the focus is shifting towards diversifying revenue streams, particularly towards NAR. Delhi and Hyderabad airports are examples of how NAR segments such as shops, rental, cargo, F&B and duty-free are becoming central to airport economics. At Hyderabad airport, NAR surged 38.4 per cent year-on-year in the second quarter of FY 2026, surpassing the 7.6 per cent growth rate in aeronautical revenue, underscoring how commercial income is now expanding more than five times faster than regulated aeronautical revenue. Delhi airport shows a similar trend, where NAR rose to Rs 17.3 billion in the first half of FY 2026, an 11 per cent year-on-year increase driven by retail, duty-free space rentals, cargo and F&B. In Q2 FY 2026 alone, Delhi’s NAR grew 8 per cent year-on-year.
Aeronautical charges are regulatorily sensitive, making them difficult to adjust quickly when debt servicing and operating costs rise. Meanwhile, NAR is generally more stable and can be secured through long-term concession agreements.
In India, the regulation tariff follows a “hybrid till” model, under which 30 per cent of NAR is used to cross-subsidise aeronautical charges. Stronger NAR allows airport operators to maintain stable and predictable aeronautical charges as traffic grows and major capital investments are undertaken.
When NAR is weak, aeronautical charges borne by airlines and passengers may witness a sharp increase, underscoring the importance of building strong NAR streams. The recent 148 per cent tariff hike approved by the Airports Economic Regulatory Authority for Delhi airport’s fourth control period ending March 31, 2029, illustrates how, in the absence of strong NAR streams, airports tend to rely more heavily on aeronautical revenue, increasing costs for both airlines and passengers.
New growth engines
Private operators are now investing in city-side development and the creation of aerotropolis to maximise land use efficiency by building hotels, offices, logistics parks, event spaces and mixed-use districts connected to terminals by automated people movers and metro links. Adani Airports is planning to develop a $2.4 billion multi-phase city-side project, with 70 per cent of the investment allocated to Mumbai and Navi Mumbai airports. It plans to increase the share of NAR to 70 per cent by 2030. Further, Phase III of the Navi Mumbai International Airport is expected to feature an integrated aerocity in addition to other airside infrastructure developments.
Sustainability as a revenue stream
Sustainability is also emerging as a key NAR driver. Hubballi airport is the first AAI airport to export solar power, earning Rs 21.3 million in direct revenue from surplus sales to the state grid. Cochin International Airport remains the world’s first fully solar-powered hub with 50 MWp capacity, while Delhi, Kolkata and Bhubaneswar airports have added sizeable solar plants to reduce costs. Beyond energy, green concessions are expanding as well. Jharsuguda airport recently opened a fast electric vehicle charging station, demonstrating how sustainability is evolving into a meaningful NAR stream. In the future, airports could even monetise carbon credits, or lease space for vertical farming to supply fresh produce to terminals and surrounding communities.
Digitalisation and integration
Digitalisation is adding another layer of revenue generation. Passenger data analytics, dynamic advertising, e-commerce tie-ups and app-based pre-ordering are emerging as avenues to increase passenger spending. With travellers remaining digitally connected, airports can deliver targeted offers, loyalty rewards and bundled services. Airports are evolving into intermodal hubs and generating revenue from retail, parking and media. For example, the newly opened foot-over-bridge at the Chhatrapati Shivaji Maharaj International Airport in Mumbai, linking Metro Line 3 directly with Terminal 2, offers potential for retail and advertising.
Similarly, the upcoming Noida International Airport has partnered with Uber to establish dedicated app-based pick-up zones, featuring real-time wayfinding and on-ground assistance. Delhi Aerocity is being developed as a full-fledged multimodal hub integrating the metro, ISBT, RRTS and airport people movers. At Delhi airport, in the first half of FY 2026, advertisement revenues increased 4 per cent year-on-year to Rs 1.1 billion and site occupancy rate grew 62 per cent, up from 60 per cent in the same period last year.
Conclusion
As India’s aviation market expands, NAR is expected to be the backbone of airport resilience. By diversifying into retail, real estate, digital services and sustainability-linked ventures, airports can transform into self-sustaining ecosystems. This shift ensures stable tariffs, attracts investment and positions airports as engines of economic growth.
