Mumbai’s aviation landscape is entering a major transition as Mumbai International Airport Ltd (MIAL) plans to begin demolishing the North Section of Terminal 1-B at Chhatrapati Shivaji Maharaj International Airport (CSMIA) from January 15, 2027. The redevelopment is being phased to minimise disruption to passengers and airline operations.

Why Is Mumbai Airport T1 Being Redeveloped?

Mumbai’s Terminal 1 is nearly 80 years old, while the airport currently handles more than 950 flight movements every day and has an overall capacity of more than 50 million passengers annually..


Under Phase 1, MIAL will focus only on the North Section of Terminal 1-B, which currently caters to around 5 million passengers per annum. Limiting the first phase to this section is intended to allow redevelopment while keeping airport operations running.

Flights to Be Shifted to T2 & Navi Mumbai Airport

The redevelopment is closely connected with the growing role of Navi Mumbai International Airport (NMIA), MIAL to start demolishing part of Mumbai airport's T1 from January 15 next year.


MIAL has begun reorganising airline operations ahead of the demolition. At least one-third of international air-traffic movements are planned to shift to NMIA from October 1, 2026, while at least one-third of T1’s traffic is scheduled to move to Terminal 2 from October 25.


Akasa Air has already moved its Mumbai domestic operations from T1 to T2, effective August 1, 2026. MIAL is also coordinating with domestic and international airlines regarding further operational changes.

A Major Transformation for Mumbai’s Airport Network

The redevelopment represents more than the rebuilding of an ageing terminal. It signals the emergence of a two-airport aviation ecosystem for the Mumbai region, with CSMIA and NMIA increasingly sharing the growing passenger and aviation demand.


MIAL has also proposed a Joint Transition Group, chaired by the Civil Aviation Secretary, to coordinate airlines, airport operators and other stakeholders and minimise inconvenience to passengers during the transition.

What Does This Mean for Navi Mumbai?

The shift of flights towards NMIA could have a wider impact beyond aviation. Greater passenger and cargo activity can support demand for hospitality, commercial spaces, logistics, warehousing, transportation and residential development around the Navi Mumbai airport corridor.


For the Mumbai Metropolitan Region, the timing is significant: Mumbai’s existing airport is being modernised while Navi Mumbai’s new airport is stepping up to absorb additional aviation demand.

The Bigger Picture MIAL to start demolishing part of Mumbai airport's T1 from January 15 next year

From Atal Setu and NMIA to the redevelopment of Mumbai’s T1, the region is undergoing one of its biggest infrastructure transformations in decades.


Mumbai Airport is rebuilding for the future—and Navi Mumbai International Airport is becoming an increasingly important part of that future.
