India has initiated a bold aviation infrastructure upgrade aimed at transforming its busiest airports into globally competitive air traffic hubs.
The move, steered by national aviation authorities, includes a sweeping assessment of international best practices, a revamp of air traffic control systems, and a roadmap to significantly boost take-off and landing efficiency at key Indian airports. In what industry experts are calling the next phase of “Aviation 2.0,” airports in Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Kolkata, Jaipur, Ahmedabad, Coimbatore and Lucknow have been earmarked for priority modernisation. These airports, which collectively handle the bulk of India’s passenger and cargo traffic, are central to a new national strategy focused on maximising runway throughput while maintaining world-class safety standards.
Documents reviewed from planning agencies reveal that India is commissioning a global benchmarking study of the world’s top-performing airports—including those in the United States, Europe, the Middle East, and East Asia. This study will analyse technological innovations, process efficiencies, and operational best practices that enable airports like Atlanta, Heathrow, and Dubai to handle high air traffic volumes seamlessly. The findings will feed into India’s blueprint for optimising its own airports. Currently, Delhi Airport is India’s busiest, with nearly 77 million passengers in 2024. Yet, it remains the only Indian airport in the global top 10. Mumbai trails at rank 31. In comparison, the United States has 15 airports in the global top 50, while China has 11. For India, bridging this infrastructure and operations gap is not just about prestige—it’s about future-readiness and sustainability in a rapidly urbanising economy.
A crucial component of this plan is the complete revamp of Air Traffic Control (ATC) towers across selected airports. These towers will be upgraded to manage not only traditional aircraft but also next-generation mobility systems including drones and electric vertical take-off and landing (eVTOL) aircraft. As India positions itself for a future dominated by sustainable air mobility, the need for advanced digital navigation and traffic coordination systems has become pressing. Aviation insiders indicate that increasing safe landings and take-offs per hour without expanding physical runway space is key to accommodating India’s surging air passenger growth. This is especially vital for cities like Mumbai and Delhi where land constraints limit runway expansion. By improving ground coordination, introducing AI-based air traffic systems, and refining standard operating procedures, India aims to match or even surpass runway efficiency benchmarks set by global leaders.
This transformation is also deeply aligned with India’s broader goals of building equitable, sustainable, and tech-integrated urban centres. Airports are no longer seen as mere transit hubs—they are critical infrastructure shaping city economies, connectivity, and climate-conscious growth. As India integrates lessons from the global aviation ecosystem, it is also setting the stage for more inclusive, efficient, and future-ready airport operations.
