Mumbai International Airport Ltd (MIAL), managed by the Adani Group, has directed certain airlines from Gulf countries to shift their flights from Mumbai to Navi Mumbai starting in the Summer 2027 season. This is necessitated by the ongoing reconstruction of Terminal 1 at the old airport.
If the airlines decline the relocation, they will have to suspend flights and return once the renovated Terminal 1 is ready in 2029. Both airports—Mumbai and Navi Mumbai—are under the management of Adani Group entities.
In a letter dated October 30, MIAL notified the Ministry of Civil Aviation (MoCA) about its plan to transfer all flights from Mumbai to 14 international destinations to Navi Mumbai, beginning in the summer of next year, specifically from late March 2027.
These 14 destinations include Bahrain, Dammam, Dhaka, Doha, Fujairah, Jakarta, Jeddah, Kathmandu, Kuwait City, Madina, Muscat, Ras Al Khaimah, Riyadh, and Sharjah.
According to Cirium's schedule for November 2026, 16 airlines operate 205 weekly flights from Mumbai to these destinations. IndiGo, Air India Group, and Akasa Air have already announced plans to move some of their services to Navi Mumbai. The remaining 12 airlines serve 102 weekly departures on these routes but have not yet issued public statements regarding the relocation of their services from Mumbai.
These 12 airlines are Air Arabia, Gulf Air, Kuwait Airways, Oman Air, Saudia, Qatar Airways, Riyadh Air, Jazeera Airways, SalamAir, Flyadeal, Flynas, and Nepal Airlines. However, it is unknown which of these airlines received the notice sent on Thursday.
Sources indicate that the notification was received by some airlines from Gulf countries. In an email addressed to the affected carriers, MIAL's slot coordination team stated that Mumbai airport's capacity will decrease by five million passengers per annum (MPPA) starting from the next summer season. Consequently, the airport will be unable to accommodate the requested flights for that season.
The letter stated: 'Therefore, Mumbai airport cannot accept the requested slots for your esteemed airline for Summer 2027, which requires a temporary transition from Mumbai starting from early Northern Summer 2027 and subsequent seasons.' The operator requested the affected airlines to move their services from Mumbai to Navi Mumbai airport. MIAL emphasized that this change is temporary, and the existing flight schedules for airlines in Mumbai will be restored after the terminal expansion is complete and additional capacity becomes available.
This notification marked an escalation of the dispute regarding MIAL's plan to shift flights to Navi Mumbai during the Terminal 1 restoration. Previously, the airport operator had asked airlines to voluntarily identify services that could be moved to NMIA to help reduce passenger traffic at Mumbai airport by five MPPA. Foreign airlines opposed this step, demanding more time and better coordination.
In its letter to MoCA dated October 30, MIAL stated that it could transfer all flights between Mumbai and 14 international destinations to Navi Mumbai if the airlines did not submit voluntary relocation proposals by November 3. It noted that consolidating these services into one airport would prevent the splitting of flights between Mumbai and Navi Mumbai.
Currently, Mumbai airport's annual capacity is approximately 55 million passengers. MIAL reported that the temporary reduction of five MPPA would leave about 91 percent of this capacity unchanged.
