Mumbai Airport's Terminal 1 Gets Major Safety Overhaul Starting January 2027

Mumbai's Chhatrapati Shivaji Maharaj International Airport is gearing up for a massive makeover of its 60-year-old Terminal 1, with Adani Airport Holdings Limited (AAHL) kicking off a phased redevelopment of the Terminal 1B North Section starting January 2027. This crucial upgrade addresses long-standing safety concerns, particularly highlighted by a fire incident in April 2025. While a significant undertaking, AAHL assures that 91% of Mumbai Airport's total passenger traffic will remain unaffected, with only about 5 million passengers annually expected to see temporary operational shifts. The decision to finally proceed with this demolition and redevelopment comes after extensive consultations with airlines since 2020 and approval from the Airports Economic Regulatory Authority of India (AERA). The North Section alone handles roughly one-third of Terminal 1 capacity, making its upgrade vital for future safety and efficiency. To minimize disruption, airlines currently operating from this section have been offered the option to temporarily move their flights to the newly operational Navi Mumbai International Airport, also managed by Adani, though some airlines are reportedly resisting this proposed shift, calling it a 'forced relocation'. Looking ahead, the redevelopment aims to boost Terminal 1 capacity by 33%, taking it from 15 million to 20 million passengers per year once completed by 2028-29. This massive project is part of a broader Rs 2,000 crore investment plan in airside projects at Mumbai Airport, designed to increase its peak-hour aircraft movements to 55 from the current 46. The strategic use of Navi Mumbai International Airport during this transition is crucial for maintaining Mumbai's position as a major aviation hub, ensuring continuous service while modernizing essential infrastructure.
