Navi Mumbai International Airport is set to receive a phased expansion of IndiGo’s international operations from February 2027, according to an announcement reported by Navbharat Times, but the final scale of the shift remains unclear because the report gives different figures for the flights involved.
The detailed announcement says IndiGo will gradually move 12 daily international services from Chhatrapati Shivaji Maharaj International Airport to Navi Mumbai International Airport between February and July 2027. The routes listed include Bahrain, Riyadh, Dammam, Jeddah, Medina, Kuwait, Ras Al Khaimah, Fujairah, Muscat, Dhaka and Jakarta. IndiGo is also expected to add a daily service to Kathmandu, taking the number of international destinations in its Navi Mumbai network to 12 during that period.
The report also says IndiGo will shift essential domestic connectivity from CSMIA to NMIA to support international transfers. Adani Airports Holdings Limited, which is working with IndiGo on the expansion, has been preparing infrastructure at Navi Mumbai to allow passengers to transfer between domestic and international services with fewer operational breaks.
The proposed move is linked to the changing role of Mumbai’s two-airport system. CSMIA is expected to undergo redevelopment of Terminal 1 by 2030, requiring airlines to adjust their operations as available capacity changes. The report says IndiGo’s domestic and international shifts are intended to contribute to that capacity adjustment while allowing the airline to continue expanding from CSMIA’s Terminal 2.
AAHL said the phased redistribution was intended to create a transparent, fair and proportionate balance of capacity between the two airports, taking into account each airline’s presence at CSMIA. According to the report, the approach is designed to reduce operational disruption and give airlines and passengers more time to plan as NMIA increases its capacity and CSMIA advances its redevelopment work.
The announcement could reshape how passengers in the Mumbai Metropolitan Region access international travel. Navi Mumbai’s location on the region’s eastern side gives the airport a separate catchment from CSMIA, although the practical impact for travellers will depend on airport access, domestic feed flights, terminal processing capacity and the final schedule of transferred services.
The supplied report, however, contains an unresolved numerical discrepancy. Its summary refers to 133 international flights shifting from CSMIA to NMIA each week, while the detailed account refers to 12 daily IndiGo flights, equivalent to 84 weekly services, and does not provide a separate schedule for Air India Group operations despite referring to them in the headline. These figures should not be treated as a confirmed combined airline schedule until IndiGo, Air India Group or AAHL publishes the final allocation.
The final dates for the service transfers and any new services at CSMIA will be announced after project coordination is completed and the required operational approvals are obtained, the report says.
