Mumbai Terminal 1 redevelopment: Winter flight slots protected as 2027 plans evolve
UPDATE — October 24, 2026: The original October 3 report below describes a plan that was subsequently revised. Mumbai International Airport Limited announced on October 13 that it would not disturb airlines’ international flight slots during the October 25, 2026–March 2027 winter schedule . Plans for Terminal 1 redevelopment and traffic balancing are still being developed; do not assume that the originally proposed 265 weekly flight reductions or passenger transfers will take effect on October 25. Always confirm your booked departure airport and terminal with your airline. Sources: MIAL operator statement and Reuters, October 13 .
What changed
Published reports indicate Mumbai Airport’s Terminal 1 is scheduled to close for roughly four years. Media coverage says the closure could push up to 10 million passengers to use Navi Mumbai’s airport instead.
Why travelers should care
The shift will alter where many flights operate from and could add time and complexity to journeys — especially for passengers who currently rely on Terminal 1’s access, transport links and services. Expect different arrival/departure points, longer road transfers, and potential changes to flight timings or schedules as airlines and ground operators adapt.
Who may be affected
Frequent users of Terminal 1, connecting passengers, and anyone booked on flights currently operating into or out of the terminal are likely to be affected. Ground-transport providers, taxi and rideshare users, and people with onward connections should pay particular attention.
Practical steps for travelers
Before travel, check your airline’s booking for any terminal or airport changes, confirm boarding passes and transfer instructions, and allow extra time for road travel between Mumbai and Navi Mumbai. Review airport websites and official airline communications for confirmed updates and transport options, and consider alternative routing if timing is tight.
What to watch next
Look for formal confirmation from airport operators and individual airlines about which flights will move, updated timetables, and any changes to baggage or transfer procedures. Local transport providers are also likely to publish new schedules and fares as the transition is implemented.
