Mumbai International Airport Limited (MIAL), operated by Adani Airport Holdings Limited (AAHL), will not proceed with its immediate plan to shift approximately 33% of international flight operations from Terminal 2 (T2). The government's decision to defer this move provides a crucial reprieve for airlines navigating existing capacity constraints and operational complexities at the busy hub.
The proposed relocation was part of a larger phased redevelopment strategy for the North Section of Terminal 1B, initially slated to begin in January 2027. This redevelopment is deemed essential due to the terminal's aging infrastructure and significant safety concerns, which became more pressing after a fire incident in April.
Terminal Redevelopment and Passenger Impact
Mumbai Airport manages around 55 million passengers annually. The redevelopment of Terminal 1B was expected to temporarily affect approximately 5 million passengers, or about 9% of the total traffic. To mitigate disruption, airlines were offered the option of temporarily moving some operations to the Navi Mumbai International Airport during the construction phases.
AAHL CEO Arun Bansal had previously stated that the redevelopment would be executed in phases, with only the North Section of Terminal 1B being demolished initially. This section accounts for roughly one-third of Terminal 1's overall capacity. He also clarified that any shifts to Navi Mumbai would be temporary, not a permanent transfer of Mumbai Airport's core operations.
Why the Deferral?
Sources indicate that the government's decision to defer the T2 international operations reduction aims to ease immediate pressure on airlines. This comes as both Mumbai and Navi Mumbai airports continue to adjust to evolving traffic patterns and capacity demands. The pause allows for more strategic planning and avoids overburdening the system while critical infrastructure upgrades are underway.
Terminal 1 has faced safety scrutiny for several years, with temporary measures keeping it operational while long-term solutions were developed. The current deferral ensures that the vital international operations at T2 can continue without additional strain, supporting smoother airline operations as Mumbai's aviation infrastructure undergoes necessary modernization.
