Mumbai's International Flights Start Moving to Navi Mumbai Airport From October 1, 2026
A meaningful share of Mumbai's international departures shift to the newly built Navi Mumbai International Airport starting October 1, 2026. If you're flying out of BOM soon, check which airport your flight actually leaves from.
If you have an international flight out of Mumbai booked for after October 1, 2026, it's worth double-checking which airport it actually departs from. A phased shift is underway that moves a meaningful share of international operations — reportedly over 30% eventually — from Chhatrapati Shivaji Maharaj International Airport (CSMIA) to the newly built Navi Mumbai International Airport (NMIA).
What's actually changing
This isn't every flight moving overnight. It's a phased transition, airline by airline and route by route, starting with a batch of international operations from October 1. CSMIA remains fully operational through the transition — this is a split, not a closure.
What to actually do about it
The airport code on your ticket (BOM vs the new NMIA code) and your airline's own advisory are the only sources worth trusting here — don't assume based on habit which airport you're flying from, especially for a booking made before this news broke. Build in extra time either way: a new airport's first weeks always run slower than its hundredth, between fresh staff, fresh signage and fresh traffic patterns on the access roads.

Is Mumbai's old airport (CSMIA) closing?
No. This is a phased shift of a portion of international operations to the new Navi Mumbai airport, not a closure of the existing one. Both airports operate through the transition.
When does the shift to Navi Mumbai International Airport start?
Some international operations begin moving from October 1, 2026, in phases, rather than all at once.
