Mumbai airport international traffic mostly unaffected by Terminal 1 redevelopment
Around 91 per cent of international passengers at CSMIA will continue operations as 39 airlines remain at the airport.
Approximately 91 per cent of international passenger traffic at Chhatrapati Shivaji Maharaj International Airport (CSMIA) will continue as normal during the redevelopment of Terminal 1, according to BusinessLine.
While 39 of the 50 international airlines will maintain operations under the Summer 2027 schedule, 11 carriers may move around 16 daily departures to the upcoming Navi Mumbai International Airport (NMIA) from late March 2027.
Major international carriers including Emirates, Etihad Airways, Singapore Airlines, SriLankan Airlines, Thai Airways, British Airways, Lufthansa, Air France and Turkish Airlines will continue to use Terminal 2.
The redevelopment of the Terminal 1 facility, which opened in 1964, follows structural and safety concerns identified in audits by Structwel in 2017 and the Indian Institute of Technology Bombay in 2024.
The transition is expected to impact five million passengers annually, representing 9 per cent of the airport's total annual traffic of 55 million. Domestic carriers such as IndiGo, Air India and Akasa Air have also planned to shift certain flights to NMIA.
The project aims to increase the terminal's capacity from 15 million passengers per annum (MPPA) to 20 MPPA. The redeveloped facility is targeted to be operational by March 2029.
