If you’re flying to or from Mumbai, you’ve probably wondered exactly how many airports the city has and which one your flight actually uses.
The short answer used to be simple, but 2026 has changed the picture. Mumbai now operates as a two airport region, with a second international airport that opened in late 2025 and is rapidly scaling up. This guide breaks down every airport serving Mumbai, what each one is used for, and what to know before you book.
Quick Answer: How Many Airports Does Mumbai Have?
As of 2026, the Mumbai Metropolitan Region is served by two major airports. The first is How Many Airports Are There in Mumbai Maharaj International Airport Mumbai’s original and still-primary airport, which handles domestic, international, and cargo traffic.
The second is Navi Mumbai International Airport Mumbai’s new second airport in Ulwe, which has been open for domestic flights since December 2025 and for international flights since mid-2026.
There’s also a third, much smaller facility Juhu Aerodrome a general aviation airfield used for helicopters, flying clubs, and private aircraft, but not for scheduled commercial flights.
For decades, Mumbai was known as a “one-airport city,” since CSMIA handled nearly all passenger traffic on its own. That changed once NMIA became operational, making Mumbai a genuine dual-hub city, similar to Delhi-NCR or Tokyo.
Chhatrapati Shivaji Maharaj International Airport
CSMIA, formerly known as Sahar Airport, is Mumbai’s main and busiest airport, and one of the busiest in India overall. It is located in the Santacruz and Sahar areas of Andheri, Mumbai, and operates two passenger terminals.
Terminal 1 has historically handled domestic flights, though it is being phased down as operations shift, with more domestic traffic moving to Terminal 2 from late 2026. Terminal handles international flights along with a growing share of domestic flights.
CSMIA sees over 52 million passengers annually, making it India’s second-busiest airport after Delhi, and it runs days a year.
The airport is operated by the Adani Group through Mumbai International Airport Limited, and it is well connected to the rest of the city by road and the Mumbai Metro.
CSMIA remains the airport most international, long-haul routes to Europe and North America, for example operate from, and it continues to be Mumbai’s primary gateway even after NMIA’s launch.
Navi Mumbai International Airport
NMIA is Mumbai’s second and newest airport, located in Ulwe, Navi Mumbai, technically in Raigad district, just outside Mumbai’s municipal limits. It was inaugurated on October 8, 2025, with domestic operations beginning on December , starting with a schedule of 23 daily departures and a first flight operated by IndiGo between Bengaluru and Mumbai.
The airport moved to operations on a phased basis from February 2026 onward, and international operations began in mid-2026, starting with limited weekly flights from carriers like Air India Express and IndiGo, later joined by Emirates, Air Arabia, Singapore Airlines, and Etihad.
NMIA’s Phase 1 is designed for roughly 20 million passengers per annum, with a full build-out across four phases planned to reach around 90 million passengers per annum by the early 2030s.
The airport is run as a public-private partnership, with Adani Airports Holdings Limited holding a 74% stake and CIDCO, a Maharashtra government body, holding the remaining 26%.
It is reachable via the Mumbai Trans How Many Airports Are There in Mumbai Link and a dedicated Mumbai Metro Line 8 has been approved to connect NMIA and CSMIA, with construction targeted for completion around 2031.
NMIA was built specifically to relieve congestion at CSMIA, and by late 2026 a meaningful share of flights including some previously based at CSMIA are shifting to Navi Mumbai as its schedule continues to expand.
Juhu Aerodrome
Juhu Aerodrome is Mumbai’s oldest airfield, located in the western suburbs. It is used primarily for general aviation, helicopter operations, flying clubs, and private or chartered aircraft, and is not used for scheduled commercial passenger flights.
While it doesn’t factor into most travelers’ plans, it’s technically the third operational airport within the Mumbai area, and is often mentioned in “how many airports” discussions for that reason.
Quick Comparison
CSMIA is the established, primary hub located in Andheri, Mumbai, handling both domestic and international flights across two terminals, with an annual capacity of over 50 million passengers.
NMIA, by contrast, is the new airport in Ulwe, Navi Mumbai, that has been scaling up since its domestic launch in December 2025 and international launch in mid-2026.
It currently operates out of a single Phase 1 terminal with more planned, has an annual capacity of around 20 million passengers in its first phase, and is set to scale up to roughly 90 million passengers as later phases come online.
Does NMIA Replace CSMIA?
No. The two airports operate as a dual-hub system for the Mumbai Metropolitan Region rather than one replacing the other.
CSMIA continues to handle the bulk of long-haul international traffic, while NMIA is absorbing growing domestic volume and an expanding international schedule as its capacity ramps up through 2026 and beyond.
What This Means for Travelers
Travelers should always double-check their airport and terminal on their ticket, especially for bookings from late 2026 onward, since airlines are actively shifting routes between CSMIA and NMIA.
Domestic flights from CSMIA’s Terminal 1 are gradually moving to Terminal 2, which may affect check-in and security arrangements.
NMIA is accessible via the Atal How Many Airports Are There in Mumbai which significantly cuts travel time from South Mumbai useful if your flight has shifted there.
A direct metro link between NMIA and CSMIA is planned but not yet operational, so it’s worth factoring in road travel time for now.
