Mumbai airport is planning to move some flights to different terminals.
Starting October 1, 2026, at least one-third of international flights from Terminal 2 will move to Navi Mumbai International Airport.

Redevelopment and Capacity Expansion
Airline and Passenger Concerns
Need for the reshuffle
Redevelopment and Capacity Expansion
MIAL says Terminal 1 is nearly eight decades old, urgently needs redevelopment, and must be modernised to support future capacity expansion.
Airline and Passenger Concerns
Airlines must reorganise established passenger bases, operational infrastructure and connectivity arrangements around Mumbai's existing airport.
Moving flights to Navi Mumbai
Redevelopment and Capacity Expansion
Navi Mumbai International Airport provides additional capacity, allowing Mumbai airport to undertake redevelopment without taking the existing airport out of operation; MIAL is offering commercial and tariff-related initiatives.
Airline and Passenger Concerns
The shift could reduce passenger convenience and increase airline operational costs, while passengers may face longer travel times and greater distances to Navi Mumbai.
Implementation approach
Redevelopment and Capacity Expansion
MIAL says the three-stage process is intended to minimise passenger inconvenience and disruption to airline operations, with coordination among authorities, airlines and airport operators.
Airline and Passenger Concerns
The transition requires airlines to begin planning early and address significant commercial, operational and connectivity challenges before the October 1 start date.
