Adani Airport Holdings will begin a two-year redevelopment of Mumbai's Terminal 1 in April 2027, requiring international airlines to either shift flights to the new Navi Mumbai airport or suspend services. This marks a strategic shift to balance air traffic across the group's airport portfolio.
Adani Airport Holdings Ltd (AAHL) has announced plans to begin a significant redevelopment of Terminal 1 at Mumbai airport starting in April 2027. This two-year infrastructure project will require international carriers currently operating from the terminal to make a choice: either migrate their operations to the newly opened Navi Mumbai International Airport or temporarily suspend their Mumbai services for the duration of the work. The move is part of the operator's broader strategy to manage traffic across its growing network of airports.
Navi Mumbai International Airport began handling international flights on July 26, 2026, and is central to the company's future growth. AAHL aims to reach a peak capacity of 20 million passengers annually at this new facility by the end of the 2028 financial year. The current projection includes a mix of 15 million domestic and 5 million international travelers. Airline engagement is already picking up, with major carriers such as IndiGo and the Air India Group announcing plans to launch 19 international routes between December and April, signaling initial commitment to the new airport.
For investors, the redevelopment of Mumbai's infrastructure is one of several large-scale investment projects planned by AAHL through 2030. The company is currently involved in substantial capital spending cycles across its airport network, including new integrated terminals in Ahmedabad and Jaipur, as well as expansions at the Thiruvananthapuram facility. These physical investments are being paired with efforts to grow non-aeronautical income, such as retail and digital services through the Adani One application. The company reported non-aeronautical revenue of ₹4,371 crore in the first half of the 2027 financial year, underscoring its focus on diversifying income streams beyond basic airport operations.
While the company expects the impact on total passenger volumes to remain minimal, the shift of international airlines to a new airport is a critical process to watch. Investors may track how smoothly these airlines transition their schedules, as any resistance or flight suspension could create short-term disruption in the airport’s passenger flow. The success of this strategy will depend on the company's ability to maintain high service standards while managing these complex, multi-year infrastructure changes across its portfolio.
