Adani Proceeds With Mumbai Airport Redevelopment as Airlines Object
Adani Airport plans to rebuild part of Mumbai airport’s Terminal 1, starting in January 2027.
The operator says the work is needed because the terminal is old and has safety concerns.
It says the rebuilt terminal will be able to serve more passengers.
During the work, Adani wants some international flights to move to Navi Mumbai or have their Mumbai departure slots temporarily removed.
Airlines do not agree with the proposed slot cuts and have asked for more information about why they are needed.
They have also taken their objection to aviation regulators.
Adani says the move to Navi Mumbai would only be temporary and that previous slots will return after the work.
The operator gives two different estimates for how much passenger traffic will be unaffected: 99% in one statement and 91% in a quoted comment.
Adani Airport says redevelopment of Mumbai airport’s Terminal 1 will begin in January 2027 and increase its annual capacity from 15 million to 20 million passengers.
The operator says around 5 million passengers a year will be temporarily affected; its statement gives differing estimates of the unaffected share: 99% and 91%.
Adani has proposed temporarily discontinuing 265 of 770 weekly international departure slots at Terminal 2 from 25 October and shifting some operations to Navi Mumbai.
Airlines have rejected the proposed slot reductions and questioned the operational basis, while saying their support for redevelopment did not mean they accepted the cuts.
The Airline Operators Committee-Mumbai escalated its objection to aviation regulators; Adani says the Navi Mumbai transition is temporary and historical slots will be restored after redevelopment.

Temporary slot changes

Adani says temporary changes and a shift of some operations to Navi Mumbai will provide capacity for redevelopment; it says historical slots will be restored, along with additional slots, once the terminal is operational.
Airlines

Basis for the proposed reductions
