Singapore to Mumbai is one of the busiest links between Southeast Asia and the Indian subcontinent, with non-stop flights in around 5½ hours and a genuine mix of full-service and low-cost carriers competing for your money. Whether you want a lie-flat cabin or the cheapest seat on a Dreamliner, this route rewards travellers who book early and stay flexible. This guide covers who flies it, a fair return fare in Singapore dollars, and when to book.
Route: Singapore Changi (SIN) → Mumbai Chhatrapati Shivaji Maharaj Intl (BOM)
Distance: approximately 3,900 km (2,430 miles)
Non-stop flight time: about 5h 20m – 5h 40m westbound
Direct flights: Yes — Singapore Airlines, Scoot, Air India and IndiGo all fly non-stop between Changi and Mumbai. One-stop itineraries exist but are rarely worth it on a route this short.
Fares from Singapore to Mumbai (SGD)
Mumbai is a year-round destination, but fares track India’s festival calendar and Singapore’s school holidays. The Diwali period (October–November), the December–January holidays and the Indian wedding season push prices up; the June–September monsoon is the quietest and cheapest window. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | — | high |
| February | — | medium |
| March | — | medium |
| April | — | medium |
| May | — | medium-high |
| June | — | low (monsoon) |
| July | — | medium (school holidays) |
| August | — | low-medium |
| September | — | low |
| October | — | high (Diwali) |
| November | — | high (festive/weddings) |
| December | — | very high |
Reference points from our own deal tracking: a strong low-cost fare (Scoot or IndiGo) can land around S$190–S$270 return, a fair typical price is roughly S$340, and anything under about S$300 is worth booking quickly. Full-service returns on Singapore Airlines or Air India usually start around S$400–S$500 outside the festive peaks.
Airlines on this route
Non-stop (about 5½ hours):
- Singapore Airlines — non-stop from Changi with a full widebody product, meals and 25–30 kg checked baggage included.
- Air India — the Indian flag carrier flies non-stop on widebody aircraft, with a full-service cabin and generous bag allowance.
- Scoot — the low-cost long-haul arm of the Singapore Airlines group, usually the cheapest headline fare; baggage and meals are add-ons.
- IndiGo — India’s largest carrier, non-stop on narrowbody aircraft with sharp fares and a big onward network across India.
Because the four carriers compete hard on a short route, non-stop is almost always the smart choice — one-stop itineraries through the Gulf or Colombo add hours without reliably saving money. Choose Scoot or IndiGo for the lowest price, or Singapore Airlines and Air India when you want the bag, the meal and the comfort included.
When to book & how to save
- Book 1–3 months ahead for the best balance of price and choice; fares on this route rarely improve in the final fortnight.
- Avoid Diwali and the December holidays — these are the busiest and most expensive weeks, and seats sell out early.
- Fly in the monsoon (June–September) for the lowest fares if you don’t mind the rain, which falls in heavy bursts rather than all day.
- Check the bag rules: Scoot and IndiGo sell the cheapest seats without checked baggage, so add a bag and compare the all-in price against Singapore Airlines and Air India.
- Mind the visa: most visitors need an Indian e-Visa arranged before departure — sort it early so it doesn’t rush your booking.
Arriving in Mumbai
International flights land at Chhatrapati Shivaji Maharaj International Airport (BOM), using the modern Terminal 2 for arrivals. The airport sits in the Andheri district, closer to the city than most major hubs. A prepaid or app-based taxi to the western suburbs runs roughly S$8–S$15 (about ₹500–900), while South Mumbai is a longer 45–75 minute ride depending on traffic. The Mumbai Metro now reaches the airport area, offering a cheap, traffic-free alternative into parts of the city — useful during rush hour, when the roads crawl.
Frequently asked questions
How long is the flight from Singapore to Mumbai?
Non-stop flights take about 5 hours 20 minutes to 5 hours 40 minutes westbound from Singapore to Mumbai. The return leg to Singapore is broadly similar. There is no need to connect — several airlines fly the route direct every day, so a one-stop itinerary only adds time.
Are there direct flights from Singapore to Mumbai?
Yes. Singapore Airlines, Air India, Scoot and IndiGo all fly non-stop between Changi and Mumbai, with multiple departures a day. Scoot and IndiGo usually carry the cheapest fares, while Singapore Airlines and Air India include checked baggage and meals in a full-service cabin.
How much does it cost to fly from Singapore to Mumbai?
A typical economy return runs about S$300–S$620 depending on the season. The best low-cost deals dip to around S$190–S$270 return during the quiet monsoon months, while the Diwali and December peaks sit toward the top of that range.
What is the cheapest month to fly from Singapore to Mumbai?
June to September is usually the cheapest, coinciding with India’s monsoon, with returns from around S$300 and low-cost fares lower still. Avoid October–November (Diwali and wedding season) and the December holidays, which are the busiest and priciest.
Which airlines fly from Singapore to Mumbai?
Non-stop: Singapore Airlines, Air India, Scoot and IndiGo. The two full-service carriers include baggage and meals; the two low-cost carriers sell a lighter fare and charge extra for bags. All four use Changi and Mumbai’s Terminal 2.
Which airport do I fly into in Mumbai?
You land at Chhatrapati Shivaji Maharaj International Airport (BOM), Mumbai’s main airport, with international flights using the newer Terminal 2. It is in the Andheri area, relatively close to the city, and well served by prepaid taxis, ride-hailing apps and the Mumbai Metro.
How far in advance should I book Singapore to Mumbai flights?
Aim to book 1 to 3 months ahead. Fares tend to climb as departure approaches, especially around Diwali, the Indian wedding season and the Christmas–New Year peak, so booking early almost always wins on this route.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) tend to be a little cheaper than Friday–Sunday, and flying out and back midweek can save S$30–S$70 on a return. Shifting your dates by a day or two is one of the easiest ways to trim the fare.
