Mumbai Airport international departure slots will remain in place for the 2026–27 winter season after the airport operator postponed a proposed transfer of 265 weekly services to Navi Mumbai International Airport, according to reports published October 13, 2026.
Mumbai International Airport Ltd. agreed after discussions with airline representatives that the planned October 25 reduction would not proceed during the winter timetable. The operator intends to continue discussing traffic changes linked to the planned redevelopment of the older Terminal 1 complex.
The announcement provides schedule certainty for airlines and travelers during the approaching winter period. It does not mean Terminal 1 redevelopment has been cancelled or that all future transfers between the two airports have been ruled out.

Mumbai Airport International Slots Remain for Winter
The previously proposed change involved 265 of 770 weekly international departures from Mumbai’s Terminal 2. That represented roughly one-third of the scheduled international departures affected by the plan, according to airport and airline reporting.
The reductions were expected to free up Terminal 2 capacity for domestic flights displaced by work at Terminal 1. Airlines objected to the timing and operational consequences of shifting already-planned services to Navi Mumbai shortly before a new timetable took effect.
Mumbai International Airport Ltd. indicated that winter slots would remain undisturbed while consultations continued. The winter scheduling season begins on October 25 and runs to late March 2027, so the deferral covers a major period of holiday and business travel.
That assurance concerns the specific airport slot-transfer proposal. Airlines can still adjust individual schedules for unrelated commercial or operational reasons; it would be inaccurate to promise that no winter flight will ever be cancelled.
Terminal 1 Redevelopment Drives the Airport Dispute
The proposed shift stems from plans to redevelop aging facilities at Terminal 1, which handles domestic operations. The operator has discussed moving some of those flights into Terminal 2 during construction, creating competing demands for gates and terminal processing space.
The initial airport plan generated objections about capacity data, passenger impacts and the logistics of using a different airport. Airline representatives also sought information on the Terminal 1 safety assessment and alternatives to the proposed 265-departure reduction.
The Indian Ministry of Civil Aviation intervened earlier in October and asked for a more consultative solution. After further discussions, the airport operator committed to protecting the winter schedule and working with carriers on a longer-term plan.
Redevelopment remains an infrastructure project with its own engineering and phasing challenges. The deferral gives planners time to reconcile construction access, terminal processing capacity and airline scheduling requirements without the immediate international slot cut.
Navi Mumbai Transfer Decisions Move to 2027
The postponement is not a permanent rejection of transfers to Navi Mumbai International Airport. Reporting on the October 13 discussions indicates that traffic balancing could begin with the following summer scheduling period, subject to agreement and a workable transition plan.
The airport operator has promised to assist carriers that choose to move operations voluntarily. That distinction matters: a voluntary airline route decision is different from an imposed reduction of flights at the existing airport.
Carriers need time to account for ground transportation, passenger connections, available slots, crew arrangements and ticketing changes. Those practical questions were central to the industry pushback, rather than opposition to airport development in principle.
Further meetings are expected to refine the implementation plan. The available announcement does not establish a final list of transferred routes, the number of airlines that will move or a revised mandatory starting date.
FAQ: Mumbai Airport international
Will Mumbai Airport reduce 265 international flights this winter?
No. The previously proposed winter-season slot reduction has been deferred, and the airport operator said existing international slot allocations would be respected.
Why were flights proposed to move to Navi Mumbai?
The operator wanted to release space at Mumbai Terminal 2 for domestic services affected by the planned Terminal 1 redevelopment.
When could Mumbai flights move to Navi Mumbai instead?
Discussions concern the summer 2027 schedule, but no final route list or mandatory transfer date has been confirmed.
Looking Ahead
The next step is a revised transition plan negotiated by the airport operator, airline representatives and aviation authorities. Reporting points to further meetings later in October, including airline-slot discussions, but final summer 2027 arrangements remain undecided. Passengers should follow their own airline’s confirmed airport and terminal information.
