A Singapore to Delhi flight takes about six hours, long enough for two films and a meal but short enough to skip the jet lag. Three airlines fly the route nonstop, and return fares in October 2026 started from around SGD 487. This guide covers the airlines, the prices, the visa rules, and the ride from Delhi airport into town.
Nonstop flights from Singapore Changi (SIN) to Delhi’s Indira Gandhi International Airport (DEL) take about 5 hours 35 minutes to 6 hours 5 minutes. Air India, Singapore Airlines, and IndiGo run about 44 nonstop flights a week between them. Singapore passport holders need an Indian e-Visa before they fly, and you apply for it fully online.
Flight Time, Distance, and the Time Difference
The route covers roughly 4,150 km, heading northwest across the Bay of Bengal. Most nonstop services land in just under six hours, though winds can shave off or add 20 minutes.
Delhi runs on India Standard Time, which is two and a half hours behind Singapore. That odd half-hour offset catches a lot of people out when they set alarms or plan calls home. One recent Singapore Airlines flight left Changi at 4:45 pm and landed in Delhi at 8:05 pm local time.
Every nonstop Singapore to Delhi flight lands at Terminal 3 of Delhi airport. It’s the biggest terminal at India’s busiest airport, so expect a long walk from the gate to passport control.
Airlines Flying Nonstop and What They Cost
Air India flies the route most often, with about 23 nonstop flights a week. Singapore Airlines runs two daily flights, and IndiGo, India’s biggest airline and a low-cost carrier, has one daily evening service. Air India and Singapore Airlines are both Star Alliance members, which helps if you collect KrisFlyer miles.
On Singapore Airlines and Air India, economy fares usually include a hot meal, with plenty of Indian vegetarian options. IndiGo sells food and drinks on board instead, so eat at Changi before you fly or pre-book a meal online.
Here’s how the three compared for return trips on Google Flights in October 2026:
| Airline | Weekly nonstop flights | Typical return fare (Oct 2026) |
| Air India | 23 | SGD 375 to SGD 860 |
| Singapore Airlines | 14 | SGD 720 to SGD 1,400 |
| IndiGo | 7 | SGD 365 to SGD 660 |
The price gap here is bigger than on most routes of a similar length from Changi. A Singapore Airlines ticket can cost twice as much as IndiGo for the same six hours in the air. If comfort and a good meal matter, the full-service fare earns its price. For a cheap Singapore to Delhi flight with just a cabin bag, IndiGo is usually the one to beat.
Older travel sites may still list Vistara on this route, but it merged into Air India in November 2024. Those former Vistara flights now run under the Air India name and booking system.
Choosing Between Red-Eye, Day, and Evening Flights
Departure times on this route vary more than people expect, and the time you pick shapes your first day in Delhi. Check the arrival time as closely as the fare before you book anything.
Singapore Airlines has run a 2:35 am red-eye that lands in Delhi around 5:40 am. It suits travellers who sleep well on planes and want a full day on arrival. If you struggle to sleep sitting up, you’ll spend that first day half awake.
Daytime departures, mostly on Air India, land around lunchtime or early afternoon. They’re the easiest option for families and first-time visitors, since you reach the hotel before dark.
Evening flights need a little more thought, mostly because of the metro. A Singapore to Delhi flight that lands after 11 pm misses the last Airport Express train into the city. Budget for a taxi or an app cab, and book your hotel’s check-in time in advance.
For the trip home, the same thinking about timing works in reverse. A late-night flight out of Delhi lands at Changi early the next morning, so plan a light day after you get back.
How to Find Cheaper Flights to Delhi
Fares on this route swing by hundreds of dollars between seasons. These five habits make the biggest difference for travellers leaving from Singapore.
1. Fly in September or October
KAYAK puts September as the cheapest month, with return fares averaging about SGD 384. Trip.com points to October, with an average of around SGD 365. Both months sit just before Delhi’s busy winter travel season begins in earnest.
2. Avoid December and the Diwali Rush
December is the priciest month on this route, with average return fares reaching about SGD 766 on Trip.com. Diwali, which falls in late October or November, also pushes prices up. Many Indian families in Singapore fly home for the festival, so seats fill early.
3. Check What the Fare Includes
IndiGo’s fares often look cheapest, but meals and extras can cost more. Before you book a budget Singapore to Delhi flight, add the bags and meals you actually need. Then compare that total with Air India, which usually includes a meal and checked bag.
4. Look at One-Stop Flights When Nonstops Are Full
During peak weeks, a one-stop route through Kuala Lumpur can cost less than the nonstop options. KAYAK showed one-stop return fares from about SGD 363 on this route. Malaysia Airlines and Batik Air both sell this kind of connection. The trip takes longer, often 10 hours or more, so it suits flexible travellers best.
5. Set a Fare Alert Two to Three Months Ahead
Track your dates on Google Flights or KAYAK, and book when the price drops near the low end of the table above. Prices often jump in the last two weeks before you fly, so a late booking is rarely a cheap one. For Diwali or December trips, start watching even earlier, ideally four months out.
Best Time of Year to Visit Delhi
Delhi’s weather is far more extreme than Singapore’s, so your travel month matters more than the fare alone. Each season brings its own trade-off for visitors from a city that stays warm all year.
From April to June, Delhi gets very hot, and afternoons often pass 40°C. July to September brings the monsoon, with heavy rain and flooded roads on some days. These months tend to have lower fares, but sightseeing can be tiring.
October to March is the most pleasant time to visit, with cool mornings and mild afternoons. The catch is air quality, which often drops sharply in late October and November. Pack a good mask if you have asthma or a sensitive chest.
Winter also brings dense fog, mostly in December and January. Fog can delay early morning landings at Delhi by several hours. If your Singapore to Delhi flight lands at dawn in winter, leave a buffer before any connecting train or meeting.
For many Singapore travellers, February and early March are the sweet spot. The fog has usually lifted, the air is clearer, and the summer heat has not yet arrived. Just watch for Holi in March, the spring festival of colours, which fills hotels and pushes up fares that week.
Visa and Entry Rules for Singapore Travellers
Singapore passport holders need a visa for India, but the process is fully online. The 30-day e-Tourist Visa costs USD 25, or USD 10 for travel between April and June. Before your Singapore to Delhi flight, check that you have these ready:
- A passport valid for at least six months from the day you arrive in India.
- An approved e-Tourist Visa from indianvisaonline.gov.in, applied for at least four days ahead.
- A return or onward ticket, since airline staff may ask for it at check-in.
- The e-Arrival Card, filed online within 72 hours before you land.
The e-Arrival Card replaced the old paper landing form, which India stopped accepting on 1 April 2026. You can file it free on the Indian Visa Online portal or the Su-Swagatam app. Save the QR code to your phone, and print a copy as backup.
Watch out for lookalike visa websites when you search for the application page. Several fake sites copy the government portal’s design and charge two or three times the real fee.
Before You Fly From Changi
Changi splits the three airlines across two terminals, so check your booking before you head out. As of our last check, flights to Delhi leave from these terminals:
- Singapore Airlines departs from Terminal 3.
- Air India departs from Terminal 2.
- IndiGo departs from Terminal 2.
The MRT stops directly beneath Terminals 2 and 3, so getting there is simple. For an international flight of this length, arrive about two and a half hours before departure. Changi screens bags at the gate, so keep liquids in your cabin bag under 100 ml each.
Getting From Delhi Airport Into the City
After a Singapore to Delhi flight, follow the signs for immigration and look for the counters marked for e-Visa holders. Queues can grow long when several international flights land together, so keep your passport and e-Arrival QR code in hand.
Terminal 3 has its own metro station, which links straight to the Airport Express Line. For most travellers, it’s the fastest way into central Delhi:
- Follow the “Metro” signs from the arrivals hall to the Airport Express station.
- Buy a token or card at the counter, paying in rupees or by card.
- Pay a fare of under INR 100, less than SGD 1.50, for the ride to New Delhi station.
- Arrive at New Delhi station about 20 minutes later, close to Connaught Place.
Prepaid taxi counters and app cabs wait outside arrivals as well. They’re easier with heavy bags or a late arrival. Delhi’s traffic, though, can stretch a 40-minute drive past an hour at rush hour. If you’re staying in Gurugram, a cab also makes more sense, since the metro needs at least one change of line.
Most travellers also want mobile data from the moment they land in Delhi. A local SIM card at the airport needs your passport and visa, and activation can take a few hours. A travel eSIM bought in Singapore before you fly is often the simpler choice.
For spending money, SGD 1 was worth about INR 75 on 30 September 2026, so SGD 100 gets you around INR 7,500. Airport money changers usually offer weaker rates than shops in the city. Change a small amount on arrival, then use an ATM or travel card once you’re settled.
