Adani Airports to expand Mumbai airport Terminal 1 capacity by 33% to 20 million passengers through phased redevelopment aided by flight shifts to Navi Mumbai

Key facts

• Adani Airports plans to increase the annual passenger-handling capacity of Terminal 1 at Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai by around 33%, from 15 million to 20 million passengers, under a phased redevelopment programme.
• The redevelopment will be facilitated by shifting some flight operations of IndiGo and Air India Express to Navi Mumbai International Airport (NMIA).
• The initial phase of the transition aims to move around 5 million passengers from CSMIA to NMIA, of which approximately 3.6 million passengers, about 70% of the first-phase relocation target, are planned to be transferred.
• The Terminal 1 redevelopment is expected to include safety improvements, modernised passenger facilities and upgrades to the terminal's operational infrastructure.
• The planned transfer of flights to NMIA followed consultations between the airport operator and airlines over nearly 18 months.
• Only 9% of CSMIA's annual 55 million passenger traffic will be temporarily transitioned under the redevelopment programme, while around 91% of the traffic will continue to operate from Mumbai Airport.
• Airlines shifting services to NMIA will retain their historical slots at CSMIA, which will be restored once the Terminal 1 redevelopment is complete.
• The City and Industrial Development Corporation (CIDCO) has built three bridges, SBR-9, BR-4 and BR-5, across Panvel Creek and the Gadhi River to improve road connectivity between NMIA, Atal Setu, Ulwe Coastal Road, Amra Marg and NH-4B.
• NMIA's Terminal 1 is designed to handle 20 million passengers annually, with further expansion planned to raise the airport's overall capacity to 90 million passengers a year.
• The development of NMIA alongside CSMIA is expected to create a dual-airport system for Mumbai, increasing the region's capacity to handle domestic and international traffic.
