The Adani Group is preparing a sweeping $15 billion expansion of its airport portfolio over the next five years, aiming to boost annual passenger capacity to 200 million as India’s aviation sector enters one of its fastest growth phases. The investment comes as the conglomerate lays the groundwork for the public listing of its airports business, according to people familiar with the strategy.

Massive Infrastructure Push Across Key Airports

Sources said the multi-year plan includes adding new terminals, expanded taxiways, and an additional runway at the upcoming Navi Mumbai International Airport, which is scheduled to open on December 25. Capacity upgrades are also planned at airports in Ahmedabad, Jaipur, Thiruvananthapuram, Lucknow, and Guwahati—all operated by Adani Airport Holdings Ltd.

The projects aim to increase handling capacity by more than 60%, not including the standalone capacities of 20 million passengers at Navi Mumbai and 11 million at the newly expanded Guwahati airport, which opens this month.

Financing the Expansion

Around 70% of the $15 billion investment will be financed through debt raised over the next five years, with the remainder coming from equity infusion, the people said. The capital structure mirrors Adani’s approach to earlier infrastructure projects, balancing long-maturity debt with strategic equity participation.

A spokesperson for the Adani Group did not respond to emailed queries seeking comment.

Why This Matters: India’s Aviation Boom

India is one of the world’s fastest-growing aviation markets. Annual passenger traffic is expected to more than double to 300 million by 2030, driven by rising incomes, deeper regional connectivity, and a surge in air travel demand from Tier-2 and Tier-3 cities.

By scaling capacity to nearly two-thirds of the projected national demand, the Adani Group is positioning itself as one of the central players in India’s aviation ecosystem. The expansion also strengthens its pitch for a planned initial public offering (IPO) of its airports unit.

The Privatization Landscape

The majority of these upgrades focus on the six airports Adani acquired in 2020, during India’s second wave of airport privatization. These facilities were previously run by the state-owned Airports Authority of India (AAI).

India’s push to privatize airports began in 2006, with GMR and GVK taking control of Delhi and Mumbai airports respectively. Adani later acquired GVK’s stake in Mumbai, consolidating its position as a major private operator.

The Indian government now plans to privatize 11 additional airports, grouping profit-making assets with loss-making ones to ensure balanced participation. Both Adani Airport Holdings—the largest operator by number of airports—and GMR Airports, the largest by passenger traffic, are expected to be the top contenders.

Aviation Ambitions Extend Nationwide

Beyond the Adani Group’s expansion, India is planning aggressive capacity growth across the sector:

Construction of a second airport in Delhi is underway to ease congestion at IGI Airport.
The government aims to expand the national airport network to 400 airports by 2047, up from the current 160.

These plans reflect India’s broader infrastructure blueprint as the country positions itself to become a top global aviation market over the next two decades.
