A Compromise After Conflict
IndiGo and the Air India Group announced plans to relocate certain international services from Mumbai's main airport to the newly opened Navi Mumbai International Airport, spreading the transition through July 2027. The phased approach resolves a recent dispute between airlines and Adani Airport Holdings, which operates both facilities, over the pace of the shift.
Airlines had resisted an abrupt move during the winter schedule, which would have required immediate operational changes. The disagreement prompted government officials to step in, leading to the current compromise that allows carriers to adjust gradually through the summer 2027 timetable.
IndiGo Takes the Lead
IndiGo will transfer the largest volume of flights under the plan. The low-cost carrier intends to launch international operations from Navi Mumbai in February 2027, moving routes over the following months. The airline will serve eleven Middle Eastern and South Asian cities from the new airport, including Bahrain, three Saudi Arabian destinations (Riyadh, Dammam and Jeddah), Madinah, Kuwait City, two UAE points (Ras Al Khaimah and Fujairah), Muscat, Dhaka and Jakarta. A daily Kathmandu service will also start, according to IndiGo.
Air India and Air India Express, both part of the Tata-owned Air India Group, will follow with their own relocations, though the announcement did not specify which routes or timelines those carriers will adopt.
Why the Original Plan Stalled
The tension arose from Adani's proposal to move international flights out of Terminal 2 at Chhatrapati Shivaji Maharaj International Airport much faster than airlines felt prepared to handle. Shifting operations to a new airport involves crew retraining, ground handling contracts, passenger communication and coordination with foreign partners. A winter schedule change would have compressed that preparation window significantly.
For Adani, operating two major airports in the same metropolitan area creates a balancing act. The company needs to justify the investment in Navi Mumbai by filling its capacity, but it also risks cannibalising traffic from the established airport if the transition is poorly managed. Airlines, meanwhile, prioritise network connectivity and passenger convenience over infrastructure politics.
The Bigger Question: Will Foreign Carriers Follow?
IndiGo and Air India moving flights addresses part of the equation, but Navi Mumbai's long-term viability as an international hub depends on whether foreign airlines with complex connecting networks choose to relocate. Carriers with multiple daily flights often prefer consolidated operations at a single terminal to simplify transfers and crew scheduling.
If international airlines decline to shift, Navi Mumbai risks becoming a secondary facility serving point-to-point routes rather than a true alternative hub. That outcome would limit the airport's appeal to business travellers and reduce the efficiency gains Adani hopes to achieve by spreading traffic across two sites.
The phased approach buys time for all parties to test the model, but it also delays clarity on whether Mumbai's two-airport strategy will function as intended or create a prolonged period of split operations that inconveniences passengers.
What It Means for Travellers
Passengers flying IndiGo to the Middle East or South Asia from Mumbai will need to confirm which airport their flight departs from starting in February. Navi Mumbai is located across the harbour from the city centre, and while new road and rail links are planned, travel times between the two airports could stretch beyond an hour depending on traffic and infrastructure completion.
For now, domestic flights and most international services will remain at the original airport, meaning connecting passengers may face longer transit times if their inbound and outbound flights operate from different terminals or airports. The staggered timeline through mid-2027 means the situation will evolve over multiple schedule changes, requiring travellers to stay alert to which facility their carrier is using.
