Mumbai Flights Shift to Navi Mumbai: Delayed to 2027

You probably saw the headline in September. A third of Mumbai’s international flights, moving to Navi Mumbai, from 1 October. It didn’t happen.

Every week someone asks me what a headline like this means for them. It’s two kinds of people. Those with a flight booked. 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. In September those weren’t the same. In October the difference showed.

Short answer: The October shift did not happen. On 6 October the Civil Aviation Ministry asked Mumbai International Airport Ltd to defer its plan to move international flights to Navi Mumbai. MIAL then told airlines it would not shift any international flights before the winter schedule ends on 27 March 2027.

The next real step is IndiGo. On 25 October it said it is in the final stages of a plan to start international flights from Navi Mumbai from February 2027, reaching 12 destinations by July. Final dates are still to be announced. Check your airline, not the headline.

What Was Proposed in September

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

So it asked airlines to move at least a third of CSMIA’s international flight movements to Navi Mumbai. By early October the plan was 265 of 770 weekly international departures, moved by 25 October.

That’s around 50 lakh international passengers a year. The rebuild of Terminal 1B’s northern portion had been planned to start on 15 January 2027. With the shift pushed back, treat that date as uncertain too.

There was a second, separate move. About a third of Terminal 1’s domestic flights were planned to shift to Terminal 2 from 25 October. That one stays in Mumbai. I couldn’t confirm it went ahead as planned, so check your booking.

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

What Actually Happened in October

Here is the part the September headlines skipped.

Every report I read before 1 October called the move proposed, planned or requested. Not one quoted an airline naming the routes it was moving. That was the warning sign.

On 6 October the Civil Aviation Ministry asked MIAL to defer its transition plan and work it out with the airlines first. Any new plan also needs regulatory approval.

A week later MIAL told airlines it did not plan to shift any international flights until the winter season ends in March 2027. Then on 25 October, IndiGo and Adani Airports announced a phased plan: IndiGo international flights from Navi Mumbai from February 2027, growing to 12 destinations by July. MIAL still wants about a third of international traffic moved by summer 2027. Several foreign airlines have pushed back.

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 Before March 2027

International flights you’ve booked from Mumbai should leave from Mumbai until the winter schedule ends. That’s MIAL’s own assurance. From February, IndiGo routes are the ones to watch.

Still, check your airline’s app and booking email a few days before you fly. Check again that morning. Plans have changed fast this year.

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? Check the terminal 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 in 2027, 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. October showed why.

The case for Ulwe and Pushpak Nagar was strong before anyone mentioned 1 October, and it’s unchanged now that the date slipped. NMIA went from 5,000 to over 22,000 passengers a day in its first four months. International flights started in July.

That growth is real, and it’s on record. The shift, whenever 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.

Want the wider picture of what’s being built around the airport? The current new residential projects in Panvel cover Pushpak Nagar and the nodes around it.

What to Watch Before February 2027

Three things will tell you whether the 2027 shift is real. All of them will be public before it happens.

Airline schedule filings. When IndiGo, Air India or a foreign carrier puts a bookable route out of NMIA on sale, that’s confirmation. A press release about a plan 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 Terminal 1 rebuild means years of work. Routes that move in 2027 are unlikely to move back quickly.

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

I will keep updating 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.
