Mumbai is one of the easiest big Indian cities to reach from Changi. A Singapore to Mumbai flight gets you there in roughly five and a half hours. Three airlines fly it without stops, and the cheapest October 2026 returns started from around SGD 345. Below, you’ll find which airport you’ll land at, when fares dip, and how to reach South Mumbai by metro.
Nonstop flights from Changi (SIN) to Mumbai’s main airport (BOM) take between 5 hours 10 minutes and 5 hours 50 minutes. You land about three hours later on the clock, since Mumbai sits 2.5 hours behind Singapore. Fares usually run lowest in August and September, right in the middle of the monsoon.
Flight Time, Distance, and Mumbai’s Two Airports
Planes cover roughly 3,900 km on this route, heading west over the Bay of Bengal and across southern India. Because the clock in Mumbai runs behind, the arrival time always looks shorter than the trip really is.
Take IndiGo’s 7:40 pm departure from Changi as an example of how this works. It has touched down at 10:50 pm Mumbai time, after about 5 hours 40 minutes on board.
For years, every nonstop Singapore to Mumbai flight landed at Terminal 2 of Chhatrapati Shivaji Maharaj International Airport. That’s starting to change. Mumbai’s second airport, Navi Mumbai International Airport (NMI), opened in December 2025 and began flights abroad in July 2026.
From 1 October 2026, airlines started moving some of their overseas Mumbai flights to Navi Mumbai in phases. The new airport sits about 46 km from the old one, on the eastern side of the harbour. Look at the airport code on your ticket, BOM or NMI, before planning anything else. The shift is meant to free up space at the main airport while its older Terminal 1 is rebuilt.
Airlines are expected to email or text passengers if a booking moves between the two airports. If your Singapore to Mumbai flight gets switched to Navi Mumbai, recheck your hotel transfer. The drive from NMI into South Mumbai takes much longer than the metro ride from BOM.
Airlines Flying Nonstop and Typical Fares
IndiGo and Singapore Airlines each run two flights a day on the route, and Air India adds one more. IndiGo, the largest airline in India, sells low-cost fares with paid extras. Singapore Airlines and Air India are full-service carriers, with meals and a checked bag in most economy tickets.
Here’s how the cheapest nonstop return fares compared on Google Flights for dates in mid-October 2026. We converted the rupee prices at INR 75 to SGD 1:
| Airline | Weekly nonstop flights | Cheapest return seen (Oct 2026) |
| IndiGo | 14 | About SGD 345 |
| Air India | 7 | About SGD 590 |
| Singapore Airlines | 14 | About SGD 635 |
On at least some of its Mumbai flights, IndiGo uses the narrow-body Airbus A321neo. These planes have no seatback screens, so load your phone or tablet with shows before leaving home. Expedia’s data shows Singapore Airlines landing on time about 92% of the time on this route, which is the best record of the three. If you’re heading over for a few days of meetings with only a backpack, IndiGo is usually the cheapest seat on the route.
Picking a Departure Time That Works
Unlike some routes to India, there are no nonstop red-eye flights from Singapore to Mumbai. Departures run from around breakfast time until about 8 pm, which keeps your options simple.
Morning departures from Changi usually land in Mumbai around lunchtime, local time, after a smooth daytime flight. IndiGo’s late-morning flight, for example, has reached Mumbai at about 2 pm local time. That leaves the afternoon free to check in, rest, and stay off the roads before the evening rush. A midday arrival also leaves time for a same-day domestic hop to Goa or another Indian city.
Evening departures suit people who want to finish work in Singapore first. The trade-off is a late landing, often close to 11 pm in Mumbai. By then, the airport metro has usually stopped for the night, so plan on a cab from the arrivals kerb.
Coming back, Singapore Airlines has run departures from Mumbai between late morning and close to midnight. That range lets you choose between a full last day in the city or an early start home.
Five Ways to Get Cheap Flights to Mumbai
Mumbai fares follow two calendars, the monsoon and the festival season. Most of the savings on a Singapore to Mumbai flight come from reading both before you pick dates.
1. Fly During the Monsoon Months
August and September are usually the cheapest time to fly, because fewer tourists want rain on holiday. KAYAK puts August at an average return fare of about SGD 285, the lowest of the year. Rain is the price you pay, and storms can also hold up departures, so keep your first day light.
2. Skip June and December If You Can
June is one of the priciest months on this route, as Indian school holidays and early monsoon travel overlap. December is the other peak, with families flying home for weddings and year-end breaks. Shifting the trip by two or three weeks often brings the fare back down.
3. Look at March for a Dry-Weather Deal
Google Flights points to March as a cheap month, with fares well below the June peak. The weather is warm but still dry, so you get lower prices without the monsoon. It suits a first visit if you’d rather skip the heavy rain.
4. Check Air India on More Than One Site
During our check, Air India’s cheapest mid-October return was about SGD 590 on Google Flights but SGD 366 on KAYAK. A gap that wide usually comes down to small date or fare rule changes. Run the same search on two or three sites before you pay.
5. Plan Around Ganesh Chaturthi and Diwali
Ganesh Chaturthi, Mumbai’s biggest festival, runs for ten days around late August or September, and hotels near the big street parties sell out. Diwali, in October or November, is when Mumbai families living in Singapore travel home, which pushes fares up. Start tracking prices about three months before either festival to catch the lower fares.
Mumbai Weather and the Monsoon Season
Mumbai is warm all year, a lot like Singapore, but the monsoon changes the whole picture from June to September. Your travel month decides whether you spend the trip exploring or waiting out the rain.
The monsoon usually arrives in early June and fades by late September, with the heaviest rain in July. Streets flood, trains slow down, and flights can face delays or diversions during the worst storms. If your Singapore to Mumbai flight lands during a downpour, give yourself extra time for the drive.
October is hot and sticky once the rain stops, so it’s not the most pleasant month. November to February is the best time to visit, with dry days, clear skies, and cooler evenings by the sea. Hotel rates climb in those months too, so lock in your room early.
March to May turns hot and humid again, with days in the mid-30s Celsius. It feels close to a Singapore afternoon, so most visitors from home cope well. Whatever month you pick, pack light cotton clothes and a small umbrella, since sea weather can turn fast.
Indian e-Visa and Arrival Card for Singapore Passports
India needs a visa from Singapore passport holders, though you never have to visit an office. Mumbai airport is one of the arrival points where India’s e-Visa is accepted. Work through this timeline before your Singapore to Mumbai flight:
- Four or more days before travel: apply for the 30-day e-Tourist Visa on indianvisaonline.gov.in.
- Fee: USD 25 for most of the year, or USD 10 for trips from April to June.
- When you book: check your passport has six months left, and keep a return ticket handy.
- In the 72 hours before landing: fill in the free e-Arrival Card, which replaced paper forms in April 2026.
- On the day: carry your e-Visa approval and e-Arrival QR code on your phone.
The 30-day e-Tourist Visa also allows two entries into India. That helps if you plan a side trip to Sri Lanka or Nepal before flying back in.
Before You Fly From Changi
As of our last check, IndiGo flies to Mumbai from Terminal 2, and Singapore Airlines and Air India use Terminal 2 or 3. The MRT drops you right under both of those terminals. If you arrive early and want a proper meal, Jewel is a short walk away through the link bridges.
Aim to reach the check-in counters at least two hours before departure. The evening Singapore to Mumbai flight tends to fill with families carrying large suitcases, so queues can build up quickly.
Getting From Mumbai Airport Into the City
Terminal 2 has its own station on the Aqua Line, Mumbai’s first fully underground metro. It opened along its full length in October 2025 and runs from the airport all the way to South Mumbai:
- From arrivals at Terminal 2, follow the walkway to the metro station, about 100 metres away.
- Board a train heading south, in the direction of Cuffe Parade.
- Get off at BKC for the business district, or stay on for Churchgate and Cuffe Parade.
- Expect the full ride south to take 40 to 45 minutes and cost up to about INR 70.
The line also stops at Dadar and CSMT, which connect to Mumbai’s suburban trains and long-distance rail.
Trains run from early morning until about 10:30 pm, so check the time if you land late. The metro beats the road at rush hour. A taxi from the airport to Colaba can then take well over an hour. Cabs still make sense with heavy bags, a late landing, or a hotel in the suburbs.
If your Singapore to Mumbai flight lands at Navi Mumbai instead, plan the ride in advance. The new airport has no direct metro to South Mumbai yet. Most people take a cab across the Atal Setu sea bridge, which crosses the harbour to the city.
As a rough guide, SGD 10 buys about INR 750 at late-September 2026 rates. Cards work in most hotels, malls, and restaurants, but carry some cash for kaali-peeli taxis and street food stalls.
Frequently Asked Questions
How long is a Singapore to Mumbai flight?
Expect between 5 hours 10 minutes and 5 hours 50 minutes in the air. Mumbai’s clock runs two and a half hours behind, so your arrival time looks about three hours after departure.

Most nonstop flights land at Chhatrapati Shivaji Maharaj International Airport (BOM), Terminal 2. Since October 2026, some overseas flights are moving to Navi Mumbai (NMI), so check the airport code on your ticket.
Do Singaporeans need a visa for Mumbai?
They do, but it’s an e-Visa you get online, and Mumbai airport accepts it. Apply at least four days ahead, then file the free e-Arrival Card in the 72 hours before landing.
When are flights from Singapore to Mumbai cheapest?
Fares usually bottom out in August and September, during the monsoon. KAYAK shows an August average of about SGD 285 for a return trip. June and December are usually the most expensive months for this route.
How do I get from Mumbai airport to Colaba?
Take the Aqua Line metro from the Terminal 2 station to Cuffe Parade, which takes about 40 to 45 minutes. A taxi works too, but traffic can make the drive much slower.
Booking Your Singapore to Mumbai Flight
Check the airport code first, because BOM and NMI lead to very different rides into the city. Then pick your month with the monsoon in mind, and run your dates on more than one booking site. With the e-Visa approved and the e-Arrival Card filed, all that’s left is the metro ride south.
