IndiGo and Air India to shift Mumbai flights to Navi Mumbai airport from 2026

Major boost for Mumbai aviation infrastructure as airlines move to Navi Mumbai hub

India's commercial aviation sector has reached a major milestone in modernising urban transport infrastructure, with IndiGo and Air India Group outlining a structured transfer of flight operations to the new Navi Mumbai International Airport.

Starting in December 2026, the strategic transition will establish an operational dual-airport system for the Mumbai Metropolitan Region. The move unlocks vital aviation capacity, eases congestion at Chhatrapati Shivaji Maharaj International Airport (CSMIA), and lays the groundwork for the redevelopment of CSMIA's Terminal 1 by 2030.

Under a joint framework operationalised with Adani Airport Holdings Limited (AAHL), IndiGo will transfer 12 daily international departures and supporting domestic connecting services to Navi Mumbai between February and July 2027. The shift is designed to transform the newly constructed airport into a premier international hub while enabling further expansion of long-haul routes from Mumbai to Asia, Africa, and Europe.

Airlines prepare phased transition to Navi Mumbai International Airport

The relocation covers a broad network of international routes, ensuring seamless domestic-to-international transfers at the state-of-the-art Navi Mumbai facility.

Air India Group will launch its presence at Navi Mumbai in December 2026 with four daily domestic flights operated by Air India Express, followed by a progressive shift of its West Asian services completed by the Northern Summer 2027 schedule.

Infrastructure delivery supports long-term national connectivity

The expansion reflects India's robust delivery of world-class infrastructure to meet soaring travel demand. By distributing operations across two complementary aviation hubs, the Mumbai region gains enhanced reliability, reduced air traffic congestion, and increased slot availability for international long-haul expansion.

IndiGo plans to utilise its growing fleet of Airbus A320, A321, and long-range A321XLR aircraft to launch new international routes from CSMIA as capacity frees up. Meanwhile, AAHL and airline partners are putting in place integrated transfer facilities at Navi Mumbai to ensure a smooth experience for transit passengers.

The coordinated dual-airport model highlights India's proactive planning in aviation infrastructure, delivering modern capacity ahead of future growth while ensuring operational stability across the nation's key economic gateways.
