Mumbai’s aviation capacity is poised for a major transformation as the Navi Mumbai International Airport is expected to become operational by June 2025, providing much-needed relief to the congested Chhatrapati Shivaji Maharaj International Airport.
The new airport, positioned as a critical infrastructural milestone, is expected to significantly rebalance Mumbai’s air traffic load, currently burdened by over 50 million passengers annually through its sole existing hub. The launch of a second commercial airport in India’s financial capital marks a strategic leap in regional connectivity and urban decongestion, with wide-ranging implications for passenger experience, airline operations, and sustainable infrastructure planning. Airlines are already recalibrating operations in anticipation of this dual-airport ecosystem. Among the first movers, the Air India Group is reportedly exploring partial migration of its domestic flights to the Navi Mumbai facility once it becomes functional. Such a transition aims to facilitate smoother operations at the saturated CSMIA and provide passengers with faster and more seamless travel experiences.
However, the shift is expected to be staggered, not sudden. IndiGo, India’s leading low-cost carrier, has made it clear that it will retain a substantial portion of its services at Terminal 1 for the foreseeable future, underscoring the importance of operational continuity and passenger convenience amid infrastructural evolution. Meanwhile, the Adani Group, which operates the Mumbai airport, is drawing up plans for extensive remodelling of the ageing Terminal 1 structures, including the potential demolition of its segments T1A, T1B, and T1C. These wings have historically handled up to 15 million passengers per annum but are now viewed as obsolete in the face of newer aviation standards. Their redevelopment could pave the way for a more technologically integrated and passenger-centric terminal, designed with sustainability and urban resilience at its core. The modernisation aligns with India’s larger aviation roadmap that aims for carbon-efficient terminals and greener airport management practices.
The dual-airport model is likely to reconfigure how Mumbai handles air traffic and logistics, with passengers benefiting from reduced congestion, faster processing times, and improved intermodal connectivity. The Navi Mumbai International Airport, being built by Navi Mumbai International Airport Limited (NMIAL), is also expected to adhere to global green building norms, reinforcing its role in enabling a more sustainable urban future. Located in one of India’s fastest-growing economic corridors, the airport’s success will not only be measured in passenger volume but in its contribution to equitable urban mobility, regional economic upliftment, and climate-responsive infrastructure.
As the June 2025 timeline draws closer, stakeholders across civil aviation, urban development, and public policy will be watching closely. The move to operationalise the Navi Mumbai airport represents more than just infrastructural expansion; it signifies a pivot towards reimagining the travel experience in one of the world’s densest urban agglomerations. While challenges around integration and transition logistics persist, the city’s collective aspiration for more humane, efficient, and future-proof transport infrastructure may well find wings in this long-awaited airport project.
