Mumbai Airport Redevelopment Plan: 91% International Traffic Unaffected During Terminal 1 Revamp

Around 91 per cent of international passenger traffic at Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) will remain unaffected during the redevelopment of Terminal 1. A total of 39 out of 50 international airlines will continue operations under the Summer 2027 schedule.

The remaining 11 airlines, which operate around 16 daily departures to select destinations, may shift their services to the upcoming Navi Mumbai International Airport (NMIA) from the end of March 2027.

Major international carriers, including Emirates, Etihad Airways, Singapore Airlines, British Airways, Lufthansa, Air France, Turkish Airlines, SriLankan Airlines and Thai Airways, will continue operating from Terminal 2.

Commissioned in 1964, Terminal 1 requires redevelopment to address structural and safety concerns. Audits conducted by Structwel in 2017 and IIT Bombay in 2024 highlighted the need to replace the ageing infrastructure with a modern facility.

The temporary redistribution of flights is expected to affect around five million passengers annually, accounting for nearly 9 per cent of CSMIA’s total annual traffic of approximately 55 million. The remaining 50 million passengers will continue using the Mumbai airport during the transition.

Domestic carriers, including IndiGo, Air India and Akasa Air, have announced plans to shift selected services to NMIA.

The redeveloped Terminal 1 will increase its annual passenger-handling capacity from 15 million to 20 million, marking a 33 per cent rise. The upgraded facility will feature improved passenger processing, security screening and modern infrastructure.

CSMIA aims to make the new terminal operational by March 2029. The airport has assured airlines that their historical slot allocations will remain protected during the transition.

The redevelopment will strengthen Mumbai’s aviation infrastructure while allowing NMIA to accommodate additional flights and ease congestion at the existing airport.
