When the new Navi Mumbai airport (NMIA) opens in less than a year, Mumbai's overcrowded Chhatrapati Shivaji Maharaj International Airport (CSMIA) will get some relief, both airside and terminal-wise. Arun Bansal, CEO of Adani Airport Holding Ltd., stated at an event on Friday that a significant amount of airside space at CSMIA would be released by relocating certain hangars, general aviation infrastructure, and cargo facilities to NMIA. He mentioned that this relocation would enable the creation of airside infrastructure, although the prospect of having two parallel runways in Mumbai was dismissed many years ago. Bansal also referenced London Gatwick Airport's plans to have two airstrips by 2029, contrasting it with CSMIA, which currently operates as the world's busiest single-runway airport. In March, Karan Adani, Managing Director of Adani Ports, informed TOI that CSMIA's old Terminal 1 (T1; domestic) would be demolished a few months after the Navi Mumbai airport becomes operational, anticipated in March 2025. The demolition of old T1 would pave the way for a new terminal to be constructed within approximately three years from the commencement of construction work. Consequently, both terminal and airside capacities at CSMIA are expected to expand in the coming years. Bansal added that NMIA would offer a larger number of parking slots to general aviation (including charters and private planes) and freighters, with many being relocated from CSMIA to NMIA.
