IndiGo will shift 12 daily international departures from Chhatrapati Shivaji Maharaj International Airport (CSMIA) to Navi Mumbai International Airport (NMIA) from February 2027 as part of a phased expansion of international operations at the new airport.
The move follows coordination between IndiGo and Adani Airport Holdings Ltd (AAHL) to expand international services at NMIA. The transition is in the final stages of operational planning, the companies said in a joint statement.
The shift will cover existing IndiGo services from Mumbai to 11 destinations: 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, the expansion is expected to take IndiGo’s international network at Navi Mumbai to 12 destinations.
IndiGo will also transfer the domestic connectivity required to support these international services from CSMIA to NMIA, allowing passengers to connect between its domestic and international flights at the new airport. The airline and AAHL are coordinating the infrastructure and operating arrangements needed to facilitate these transfers.
The move is expected to strengthen Navi Mumbai’s role as a second aviation hub for the Mumbai Metropolitan Region while easing congestion at the capacity-constrained CSMIA.
At the existing airport, the shift will free up capacity for IndiGo to introduce additional international services across Asia, Africa and Europe in 2027. The airline plans to use its expanding fleet of A320 and A321 aircraft, including the A321XLR, for its network expansion.
The transition will also contribute to capacity adjustments required for the redevelopment of CSMIA’s Terminal 1 by 2030. IndiGo and AAHL said they would coordinate to accommodate any further changes to the airline’s operations at Terminal 1 within Terminal 2 as redevelopment progresses.
The phased transfer is intended to distribute operations between Mumbai’s two airports while minimising disruption for airlines and passengers. The companies said the approach would take into account each airline’s presence at CSMIA and provide greater certainty as Navi Mumbai expands and the existing airport undergoes redevelopment.
The final dates for shifting flights and introducing new services will be announced after coordination is completed and the necessary operating approvals are obtained.
The expansion is expected to increase international travel options from Navi Mumbai while creating additional capacity at CSMIA for new routes and infrastructure upgrades. Passengers will need to check their departure airport carefully as services are transferred in phases.
IndiGo operates more than 430 aircraft and runs nearly 2,200 flights daily, connecting over 95 domestic and 40 international destinations, according to the company.
AAHL, part of Adani Enterprises Ltd, operates eight airports, including those in Mumbai and Navi Mumbai.
