4 Oct
Summary
- Terminal 1B redevelopment starts January 2027 due to safety issues.
- This will impact 9% of annual passengers, with options to shift.
- Capacity will increase by 33% after redevelopment to 20 million passengers.

Adani Airports is set to commence the phased redevelopment of Mumbai Airport's Terminal 1B in January 2027. The initial phase involves demolishing the North Section of the terminal, identified as a significant safety concern, to minimize disruption.
This extensive upgrade will temporarily impact about 9% of Mumbai Airport's annual passenger traffic, affecting approximately 5 million travelers. Airlines have been given the option to temporarily transfer operations to the Navi Mumbai International Airport, with support provided for this transition.
The redevelopment is projected to increase Terminal 1's capacity by 33%, raising it from 15 million to 20 million passengers annually. This will allow for the restoration of all historical flight slots and the addition of new ones for airlines.
Consultations regarding Terminal 1's future have been ongoing with airlines since 2020. The project is designed to allow T1 to be redeveloped in stages, utilizing the Navi Mumbai Airport as an alternative, thus limiting overall inconvenience to passengers and airline operations.
