Mumbai Airport T1 Set for Phased Redevelopment
Chhatrapati Shivaji Maharaj International Airport begins T1 overhaul. Learn how the phased redevelopment will impact your flight operations.

Mumbai Airport T1 redevelopment is officially underway as part of a massive modernization programme at Chhatrapati Shivaji Maharaj International Airport (CSMIA). According to aviation industry sources, the terminal is undergoing a comprehensive overhaul to replace aging structures with high-capacity, modern infrastructure.
Minimal Disruption for Travelers
Despite the massive scale of the construction work, officials have structured operations to ensure that the vast majority of travelers face no significant delays. Industry sources have confirmed that approximately 91% of the total passenger traffic will remain completely unaffected during this transition.
To manage the construction without halting the airport's vital functions, the redevelopment plan follows a phased approach. Rather than a complete shutdown, the terminal is expected to undergo partial closures, allowing the airport to balance heavy infrastructure work with ongoing flight operations.
Modernization and Upgraded Facilities
The goal of this extensive project is to transform the existing Terminal 1 into a world-class facility. The modernization plan includes several key upgrades:
- Advanced Baggage Handling: Implementation of new systems to increase efficiency and reduce wait times.
- Upgraded Airside Access: Improved connectivity and flow for aircraft and ground staff.
- Seamless Transit Links: Enhanced inter-terminal links to ensure smoother movement for passengers.
Potential Operational Shifts
While most passengers will experience business as usual, some shifts in operations are anticipated. Sources suggest that certain flight operations may be relocated from T1 to the nearest available terminal options to accommodate the construction zones.
At this stage, specific details regarding the exact timeline for the redevelopment, the specific airlines that may be impacted, or the precise schedule of partial closures have not yet been released to the public. Travelers are advised to stay updated as the phased modernization progresses.
