Mumbai International Airport Limited (MIAL) operates Chhatrapati Shivaji Maharaj International Airport (CSMIA). Starting later this year, the airport will undergo a transformation with the redevelopment of Terminal 1 (T1). The airport operator hopes to complete the redevelopment by 2028-29, and capacity will be boosted by 42%.
Mumbai Airport’s Terminal 1 Redevelopment
The new Terminal 1, with a built-up area of over two million sq. ft., will be redeveloped in phases to minimise disruption to airport operations. The initial phase involves demolishing the existing structure, starting in November 2025, followed by constructing the new terminal.

CSMIA T2 and the Navi Mumbai International Airport, scheduled to be operational in H1 2025, will manage the capacity gap created by the demolition of T1. Together, the airports will accommodate passengers and flight schedules to meet the growing demands of both Mumbai City and the Mumbai Metropolitan Region (MMR). Once complete, the new Terminal 1 will be able to manage 20 million passengers annually, a 42% boost in capacity. Additional service staff will be deployed at key locations to assist passengers during peak travel. Airlines and other stakeholders will be informed well in advance to ensure uninterrupted flight schedules.
Mr Jeet Adani, Director of Adani Airport Holdings Limited, had this to say about the plans,
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.
According to Adani Airports, the new Terminal 1 at CSMIA, upon completion in 2028-29, aspires to be India’s first brownfield, biophilic, sustainable airport.
A complete overhaul of the Passenger Terminal Building will accommodate domestic operations while allowing the future integration of international services. With a capacity of 20 million passengers per annum (MPPA), this terminal will meet the growing demands of India’s burgeoning aviation market.
The redevelopment also promises state-of-the-art infrastructure upgrades, including district cooling, cutting-edge electrical substations, and a revolutionised baggage handling system, according to the Airport’s press release. The terminal will also have a Multi-Modal Transit Hub (MMTH), where passengers will be able to have direct metro access and underground bus stations.
The Terminal will feature a biophilic design—an oasis of indoor greenery, natural light, and open spaces designed to uplift and energise travellers. Its architecture will incorporate futuristic, wave-inspired forms, drawing inspiration from the fluid motion of ocean waves. Thus, it will set a bold new benchmark for eco-conscious airports of tomorrow.
Bottomline
As has been rumoured for some time, Mumbai Airport Terminal 1 will be shut for redevelopment in 2025. In the interim, the airport will move its operations to Terminal 2 and the yet-to-be-commissioned Navi Mumbai International Airport. When the airport terminal is back in action, it will be able to handle 20 million passengers per annum and will be more digitised and sustainable.

The surge in airport usage is phenomenal and so is the transformation of the T2 Internet’s facilities but alas the surge has gone past manageable levels already.
The roads leading to the airport are a nightmare with the Mumbai traffic police seemingly having abdicated all responsibility for traffic management. Even their mailbox is full so clearly they are not even receiving let alone acting on inputs from the public.
The airport approach road from the Leela hotel is a nightmare of double and triple parked vehicles 24/7. The upturn at the Lalit intercon is a nightmare causing delays of up to 15 mins even past midnight.
The traffic junction near the Leela, the one at Marol Naka and several others in the vicinity have been left unattended manned only by contract labour wardens who are powerless to enforce any rules.
No political party deserves to compete or win any elections unless they can show evidence of a. Lead enforceable plan to combat this daily nightmare.
None of the airlines wanted to shift complete operations to NMIA when asked by Adani. I remember the news of both indigo and air india refusing them.
Do you think this is a clever way to force airlines’ hand? Not to say T1 renovation was not required, but this announcement was expected after couple of years when new airport gets stabilized.
How well they are able to operate out of new airport without glitches at relatively high volumes after T1 closes down will be interesting to see.
Also starting renovation project at CSMIA when NMIA is being built would also stretch their finances
