The Airline Operators Committee, representing 47 carriers, has rejected Mumbai International Airport Limited's (MIAL) proposal to reallocate international flight slots to the new Navi Mumbai airport. Airlines are demanding transparency regarding Terminal 1 refurbishment plans, creating uncertainty for the 2027 summer flight schedule transition.
A major dispute has emerged between the operator of Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) and the airlines that operate from the city. The Airline Operators Committee, which represents 47 domestic and international carriers, has officially refused to agree to the proposal by Mumbai International Airport Limited (MIAL) to move certain international flights to the upcoming Navi Mumbai International Airport (NMIA).
Airlines Seek Transparency on Terminal 1 Plans
The primary point of friction is the lack of technical clarity regarding the renovation plans for Terminal 1 at the existing Mumbai airport. Before moving international flights to the new facility, airlines are demanding a detailed breakdown of the upgrade plans, including specific timelines, the scope of the construction, and verified data on how much operational capacity will remain available. The airline committee has explicitly stated that simply participating in preliminary discussions with airport planners does not constitute collective consent for redistributing traffic. Carriers are insisting that these operational details must be reviewed jointly before any alternative arrangements are finalized.
Stalled Transition Timeline for 2027
MIAL, which is majority-owned by Adani Airport Holdings, has been pressing for the consultation process to be completed by October 21, aiming to finalize traffic shifts for the 2027 summer schedule. However, the airline committee has signaled that it will not bypass established slot allocation guidelines to meet these deadlines. This follows previous regulatory tension when the Civil Aviation Ministry had to intervene after the airport operator proposed canceling one-third of international slots, a move that was subsequently delayed.
For investors, this deadlock creates uncertainty regarding the operational rollout of the Navi Mumbai airport. The ability to effectively balance traffic between the two hubs is a critical element for the long-term scaling of airport operations in the Mumbai region. As the transition timeline remains in limbo, the key monitorable for stakeholders will be whether the Civil Aviation Ministry intervenes again to mediate the dispute or if MIAL provides the granular operational data the airlines are requesting to move the process forward.
