Airlines operating out of Mumbai keep their winter slots at Terminal 2, after Adani Airport Holdings postponed its plan to shift international services to Navi Mumbai until the summer schedule starting March 2027.

The delay follows a meeting on Tuesday between Adani Airport Holdings leadership and the Airline Operators Committee of Mumbai Airport. Jeet Adani, Director of Adani Airport Holdings, and CEO Arun Bansal represented the operator, according to a statement from a Mumbai Airports spokesperson. The spokesperson said they assured carriers that there would be "mini" changes — the statement appears truncated, but the substance is clear: airlines bought time.

For carriers, the defusal matters. A forced mid-winter move of international operations to a new airport would have meant reworking schedules, re-filing slots and renegotiating ground handling at short notice. Holding the winter season intact protects their existing distribution of capacity across Mumbai's terminals.

Why did Adani want to move the flights?

The operator's plan wasn't about Navi Mumbai for its own sake. Adani wants to free up capacity at Terminal 2 for domestic flights displaced by the rebuild of Terminal 1. Consolidating international operations at the new Navi Mumbai airport would clear room at T2 while the construction work shrinks the domestic footprint.

That logic puts two airline constituencies in conflict: domestic carriers losing Terminal 1 capacity during the rebuild, and international carriers facing relocation to a facility further from Mumbai's core market. Tuesday's meeting surfaced that tension, and the operator chose to buy peace rather than force the shift into the winter season.

The takeaway: Adani has traded schedule disruption now for a bigger structural move later.

What changes for airlines and sellers?

In the near term, nothing. Winter slots at Terminal 2 stay as filed, so airlines' Mumbai capacity, connections and onward distribution through the hub remain stable for the season. GDS schedules, interline timing and bank structures built around T2 operations don't need to be redrawn.

The real test comes with the March 2027 summer schedule. That's when international carriers will have to commit to Navi Mumbai — a shift that will reshape where long-haul and regional international traffic touches the Mumbai market, and which terminal-dependent services, from lounges to transfer desks, capture it.

For travel sellers, the two-year runway is the working assumption to plan against, not a final settlement.

Is the dispute fully resolved?

Not quite. Tuesday's agreement defers the relocation; it doesn't cancel it. The underlying constraint — Terminal 1's rebuild displacing domestic flights that need somewhere to go — remains, and the operator will keep pressing to rebalance capacity across its Mumbai assets.

The airlines' leverage is that a coordinated move of international operations is operationally messy and commercially sensitive enough that the operator can't impose it unilaterally mid-season. That's why the concession came quickly, at a single meeting with the operators' committee.

Expect further negotiation before the summer 2027 cutover, with the terminal rebalancing plan and the pace of the Terminal 1 rebuild as the variables that will decide whether the March 2027 date holds.
