The Engine Behind the Expansion: UDAN
At the heart of this ambitious plan is the Ude Desh ka Aam Naagrik (UDAN) scheme, a regional connectivity program launched in 2016. The scheme's motto, which translates to "Let the Common Citizen of the Country Fly," captures its core objective: to make
air travel affordable and accessible for the masses, not just a luxury for those in metros. The government plans to invest approximately ₹30,000 crore to develop these airports over the next decade. This initiative, recently extended as 'Modified UDAN', will run from 2026 to 2036, focusing on developing new airports from existing airstrips and reviving underutilised ones, particularly in Tier-2 and Tier-3 cities. The model works by providing financial support, known as Viability Gap Funding (VGF), to airlines to operate on routes that might not otherwise be commercially sustainable. This subsidy, combined with capped airfares, helps bridge the economic gap and encourages airlines to connect India's vast hinterland.
More Than Just Runways: The Economic Blueprint
The plan to build 100 new airports is about more than just passenger convenience; it's a strategic pillar for economic development. By connecting remote and underserved regions, the government aims to unlock local economies, boost trade, and promote tourism. Before the UDAN scheme, regional aviation was hampered by high costs and a lack of infrastructure, concentrating air traffic in major hubs and limiting growth in smaller towns. The expansion aims to reverse this by creating new economic corridors. Improved air access makes smaller cities more attractive for business investment, conferences, and the establishment of corporate Global Capability Centres (GCCs). This is expected to stimulate sectors like hospitality, logistics, and manufacturing, leading to job creation and balanced regional growth. For local industries, from pharmaceuticals to textiles, direct air cargo access can reduce transit times and costs, making them more competitive globally.
Progress Report from the Tarmac
The push for regional connectivity is not starting from scratch. Over the last decade, India's airport network has already more than doubled, growing from 74 airports in 2014 to 166 as of September 2026. The UDAN scheme has been instrumental in this growth, operationalising hundreds of new routes connecting dozens of previously unserved or underserved airports, heliports, and even water aerodromes. As of mid-2026, the scheme has enabled over 1.68 crore passengers to travel on more than 3.58 lakh flights. Cities like Darbhanga, Mysuru, and Jorhat have gained new connections to major hubs like Bengaluru and Kolkata. The introduction of helicopter and seaplane services under different phases of UDAN has also been crucial for reaching difficult terrains and island territories, enhancing last-mile connectivity.
Headwinds and Commercial Viability
Despite the successes, the path to a fully connected India faces significant turbulence. A key challenge is ensuring the long-term sustainability of these regional routes. Many routes remain dependent on government subsidies (VGF) to stay operational. A 2023 audit by the Comptroller and Auditor General (CAG) pointed out that over half of the routes awarded in the initial phases never commenced operations, and many that did were discontinued once the three-year subsidy period ended. Airlines cite challenges like weak passenger demand on certain routes, aircraft shortages, and high operating costs as major hurdles. The new 'Modified UDAN' scheme attempts to address this by providing longer-term operational and maintenance support. However, the ultimate test will be whether these new airports and routes can generate enough organic demand from tourism and business to become self-sufficient.
Connecting to a $5 Trillion Ambition
Ultimately, the plan for 100 new airports is deeply integrated with India's larger economic vision. The Ministry of Civil Aviation's 'Vision 2040' projects that total air traffic could grow six-fold to over a billion passenger trips annually. Expanding airport infrastructure is essential to handle this projected demand. By decentralising aviation away from congested metro hubs, the government hopes to create a more resilient and efficient national logistics network. This infrastructure is seen as a critical enabler for India's ambition to become a $5 trillion economy. The success of this massive aviation push will depend on overcoming the economic and logistical challenges, but if successful, it could fundamentally redraw India's economic map, bringing millions of people from smaller towns into the mainstream of national growth.
