Mumbai Airport’s Terminal 1 will undergo a much-needed renovation starting November 2025, with some flights shifting to the upcoming Navi Mumbai International Airport to address the capacity gap. Read on to know more.
Mumbai Airport Terminal 1
Mumbai’s Chhatrapati Shivaji Maharaj International Airport (BOM) has two terminals – the older Terminal 1 and the larger and newer Terminal 2. Terminal 1 has been in use for a very long time and has not undergone redevelopment. However, that is going to change soon.
Starting November 2025, Terminal 1 will undergo renovation. The project will begin with the demolition of the existing structure in November, followed by construction of the new terminal. The upgraded terminal will boost capacity by +42% to serve 20 million passengers annually. The redevelopment will be carried out in phases to minimise disruption to airport operations.
The team at CSMIA is working tirelessly with our stakeholders to ensure a smooth transition, with minimum disruption to daily operations or passenger experience. This redevelopment is not only about expanding capacity – it is about future-proofing our city’s place on the global stage. Our priority remains to deliver the exceptional service that our passengers have come to expect.

Terminal 2 and the upcoming Navi Mumbai International Airport (NMI), scheduled to open in April 2025 with flights expected to begin in May 2025, will handle the resulting capacity gap during the renovation of Terminal 1.

Sustainability at the core
Expected to be completed in 2028-29, the revamped Terminal 1 will emphasise sustainability and aim to be India’s first brownfield, biophilic airport. Mumbai International Airport aims to integrate sustainability and innovation into the new terminal design, with a focus on digitalisation across the 2 million square feet space.
The terminal will overhauled to accommodate domestic operations while allowing for future integration of international services. The redevelopment will include several key infrastructure upgrades, such as district cooling systems, advanced electrical substations and a revamped baggage-handling system. These improvements aim to streamline airport operations, both airside and landside.
A notable addition is the Multi-Modal Transit Hub, which will connect Mumbai’s air, rail and road networks. The hub will provide direct metro access and underground bus stations, offering more convenient transport for passengers. Sustainability is a key focus in the terminal’s design. Biophilic elements such as indoor greenery, natural light and open spaces will create an uplifting environment for passengers, according to the group.
Much needed
Currently, Terminal 1 at Mumbai Airport handles all domestic flights of Akasa Air, SpiceJet, Star Air and some flights of IndiGo. According to a report released recently, the terminal’s structural integrity is weak and that, a full renovation is much needed.
With the terminal undergoing renovation soon, Navi Mumbai International Airport is expected to handle 10 million passengers per annum in its initial phase. According to a news report, the airport authorities have asked airlines operating from T1 to start planning their schedules of the upcoming winter schedule, set to begin on 26th October 2025, in line with the shift to Terminal 2 and the Navi Mumbai International Airport. It will be interesting to see how airlines plan their schedule around this.
