Adani Airport Holdings Ltd (AAHL) announced it will begin the phased redevelopment of Mumbai airport’s Terminal 1 from January 2027. The company said the majority of passenger traffic at Mumbai airport will remain unaffected during the redevelopment, which is expected to maintain around 99% of operations. Mumbai airport handled nearly 16 million international passengers in fiscal year 2026, with a maximum capacity of 55 million annually, according to livemint.com.
The redevelopment plan includes temporarily cutting international departure slots at Mumbai airport and shifting about a third of international operations to Navi Mumbai airport, located approximately 50 km away. However, airlines have rejected the proposal to reduce slots and relocate flights to Navi Mumbai. To address cost concerns, Adani Airports plans to offer cash vouchers to international passengers shifted to Navi Mumbai to offset the higher User Development Fee (UDF) charged there compared to Mumbai airport. Navi Mumbai is also offering a 100% discount on landing fees for new international flights, per livemint.com.
Adani Airport Holdings Ltd operates both Mumbai and Navi Mumbai airports and is India’s second-largest airport operator by revenue after GMR Airports. It manages eight airports and handles 23% of India’s domestic air passenger traffic. The redevelopment of Mumbai’s Terminal 1 aims to enhance capacity and infrastructure at one of India’s busiest international airports, which is critical given the growing demand for air travel in the region, according to livemint.com.
Adani Airport’s chief executive Arun Bansal confirmed the redevelopment timeline and emphasized that passenger traffic disruption will be minimal. The phased redevelopment starting January 2027 will focus on maintaining service levels while upgrading facilities at Mumbai airport, which remains a key hub for international and domestic flights in India, as reported by livemint.com.
