Oct 1 Flight Shift to Navi Mumbai: What’s Confirmed So Far

You have probably seen the headline by now. Thirty percent of Mumbai’s international flights, moving to Navi Mumbai, from 1 October.

Every week someone asks me what a headline like this means for them. Right now it’s two kinds of people. Those flying out in October. And those wondering whether to book that Ulwe flat before prices jump.

Both deserve the same thing first. What has actually been decided, and what has only been proposed. Right now, those aren’t the same.

Short answer: Mumbai International Airport Ltd has proposed moving at least a third of CSMIA’s international flights to Navi Mumbai from 1 October 2026. The reason is to rebuild Terminal 1. Separately, about a third of Terminal 1’s domestic flights are planned to move to Terminal 2 from 25 October.

As of 23 September, no airline has publicly confirmed which of its routes will move. Check your airline, not the headline.

What Has Actually Been Announced

MIAL runs Mumbai’s main airport, CSMIA. It wants to rebuild Terminal 1. To do that, it needs space.

So it has asked airlines to move at least a third of CSMIA’s international flight movements to Navi Mumbai. The proposed start is 1 October 2026.

That’s around 50 lakh international passengers a year. The rebuild of Terminal 1B’s northern portion is planned to start on 15 January 2027.

There’s a second, separate move. From 25 October, about a third of Terminal 1’s domestic flights are planned to shift to Terminal 2. That one stays in Mumbai.

IndiGo, SpiceJet, Alliance Air and Star Air currently fly from Terminal 1.

What Is Not Confirmed Yet

Here is the part the headlines skip.

Every report I’ve read calls the 1 October move proposed, planned or requested. Not one quotes an airline naming the routes it’s moving.

Mumbai Live, reporting today, puts it plainly. There’s still limited clarity on which Air India routes, if any, could move.

Reports since August describe the same thing: a plan, not a schedule. The final list of airlines and routes may change right up to the switch. That isn’t me being cautious.

And we’ve been here before. In April, CIDCO projected 35 international flights a day from NMIA, starting in May.

What actually launched on 15 July? Air India Express to Abu Dhabi, three times a week. The airport grew fast. The projection still missed by a mile.

If You Are Flying in October

Don’t assume your flight leaves from the airport printed on a ticket you booked months ago.

Check your airline’s app and booking email a few days before you fly. Check again that morning.

If your flight has moved, NMIA is a very different journey. From South Mumbai, you’re crossing Atal Setu. From the western suburbs, it’s a long drive. Leave far more time than you would for Sahar.

Flying domestic from Terminal 1 after 25 October? Check that too. Same airport, different terminal, and the walk between them isn’t short.

What It Means for Ulwe, Pushpak Nagar and Dronagiri

Now the question my other callers are asking.

If a third of Mumbai’s international traffic really does move, it’s a big deal for the nodes around the airport.

More flights means more crews, ground staff, cargo handlers and hotel workers. They all need somewhere to live nearby. That’s steady rental demand, the kind that doesn’t depend on a boom.

But I wouldn’t pay extra for a flat on the strength of this headline. Not yet.

The case for Ulwe and Pushpak Nagar was strong before anyone mentioned 1 October. NMIA went from 5,000 to over 22,000 passengers a day in four months. International flights started in July.

That growth is real, and it’s on record. The October shift, if it happens in full, speeds up something already underway. It isn’t the reason to buy.

Want to be close to the airport with a clean paper trail? Pushpak Nagar is where the options sit today.

Riddhi Siddhi Apartment in Pushpak Nagar by Chaitanya Ganesh Builders starts from ₹31.44 lakh. It’s MahaRERA-registered as P52000052276, with possession due June 2027.

Delta Greens by Delta Group runs from ₹49.10 lakh to ₹97 lakh. It’s registered as P52000034901, with possession due March 2027.

What to Watch Before 1 October

Three things will tell you whether this is real, and they will all be public within days.

Airline schedule filings. When Air India, IndiGo or a foreign carrier lists a route out of NMIA from October, that’s confirmation. A press quote about intentions isn’t.

Which routes, not how many. Moving short Gulf routes is very different from moving long-haul Europe flights. The first adds volume. The second changes who flies through NMIA.

Whether it sticks. A rebuild starting in January 2027 means years of work at Terminal 1. Routes that move now are unlikely to move back quickly.

That’s the part that matters for property. Far more than the date itself.

I will update this page as airlines confirm. For how NMIA got here, read our piece on the July international launch. For which airport nodes suit which buyer, see our guide to property near Navi Mumbai airport.
