Navi Mumbai International Airport will begin receiving progressively shifted domestic and international flights from IndiGo and Air India Group from December 2026, as Mumbai prepares to redevelop Terminal 1 at Chhatrapati Shivaji Maharaj International Airport and distribute operations across its two-airport system.
IndiGo plans to transfer 12 daily international departures from CSMIA to NMIA. The services will cover Bahrain, Riyadh, Dammam, Jeddah, Madinah, Kuwait, Ras Al Khaimah, Fujairah, Muscat, Dhaka and Jakarta. The airline will also introduce a daily service to Kathmandu. Between February and July 2027, IndiGo’s international network at Navi Mumbai is expected to reach 12 destinations.
The airline will shift the domestic operations required to support these international services as well. This will allow passengers to connect between domestic and international flights at NMIA, rather than relying on transfers between Mumbai’s two airports. Adani Airport Holdings Ltd, the airport operator, has been working with IndiGo to put the necessary infrastructure in place, according to the report.
The transfer is intended to release capacity at CSMIA for new international services. IndiGo is expected to use that capacity to introduce additional routes to destinations across Asia, Africa and Europe in 2027, supported by its expanding fleet of Airbus A320, A321 and A321XLR aircraft.
Air India Group will also move part of its West Asia network to NMIA. Air India Express will start four daily domestic flights from the airport in December 2026. Planned services to Kuwait and existing services to Oman are scheduled to follow in January 2027. The airline will then progressively transfer services to Jeddah, Riyadh, Dammam, Doha, Muscat and Sharjah.
Air India Group’s transition is expected to be completed by the Northern Summer 2027 season. The group said the move followed discussions with the airport operator and formed part of a wider plan for Indian and international airlines to redistribute operations between Mumbai’s two airports.
The two-airport arrangement is being developed alongside the proposed redevelopment of CSMIA’s Terminal 1, which is planned for completion by 2030. The shift will allow airlines to continue serving the Mumbai market while operations are reorganised and capacity is created at the existing airport.
For passengers, the operational change will make the location of a flight an increasingly important part of travel planning. Domestic and international services linked to the same airline may operate from NMIA, while other flights continue from CSMIA. The supplied report does not specify the final terminal allocation, airport access arrangements or the detailed timetable for each transferred service.
The transfer will be implemented in stages, beginning with IndiGo and Air India Express domestic operations in December 2026, followed by additional international services through 2027. The process is scheduled to conclude for Air India Group by the Northern Summer 2027 season, while the CSMIA Terminal 1 redevelopment is planned to continue until 2030.
