Fares from Singapore to Delhi (SGD)
Delhi is best in the cool, dry winter (October–March), which is also the busiest and priciest window along with the Christmas/New Year and Diwali peaks. The hot pre-monsoon months (April–June) and the summer monsoon are cheaper, if you can handle the heat. 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 | — | high |
| March | — | medium-high |
| April | — | medium |
| May | — | low-medium (hot) |
| June | — | low |
| July | — | medium (school holidays) |
| August | — | medium |
| September | — | low-medium |
| October | — | high (Diwali) |
| November | — | high |
| December | — | very high |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 5¾ hours):
- Singapore Airlines — non-stop from Changi Terminal 3; full-service with checked baggage and meals included.
- Air India — the Indian flag carrier’s non-stop, with generous baggage and onward connections across India.
- IndiGo — India’s big low-cost carrier flies the route non-stop; a leaner fare, so check bag and seat extras.
One-stop (sometimes cheaper, about 9–14 hours total):
- AirAsia / Malaysia Airlines via Kuala Lumpur — frequent connections, often the lowest headline fare.
- Indian carriers via Chennai, Bangalore or Mumbai — handy if you are visiting more than one Indian city.
- Full-service one-stops via Bangkok or Gulf hubs — worth a look when the non-stops are pricey on your dates.
Three non-stop carriers keep this route competitive, so fares are usually reasonable outside the festival peaks. If time matters, the non-stop is a straightforward evening or overnight hop; if price is the priority, a single stop through Kuala Lumpur is the usual sweet spot.
When to book & how to save
- Book 2–3 months ahead for the October–March winter season and the Diwali and Christmas peaks; short-notice fares rarely improve.
- Travel in the shoulder or low season (April–September) for the cheapest fares — Delhi is hot then, and July–September brings monsoon rain, but the seats are cheap.
- Avoid Diwali (October/November) and Christmas/New Year, the busiest and dearest windows.
- Compare bags on IndiGo: the low-cost fare may exclude checked baggage, so add it before judging it against Air India or Singapore Airlines.
- Sort your visa early: most visitors need an e-Visa or regular visa for India — arrange it well before departure.
Arriving in Delhi
Flights land at Indira Gandhi International Airport (DEL), about 15 km southwest of central Delhi; long-haul services use the modern Terminal 3. The quickest way into town is the Airport Express Metro to New Delhi station (around 20 minutes, well under INR 100 / about S$ 1.50). A prepaid or app-based taxi to the centre costs roughly INR 400–700 (around S$ 6–11) and takes 30–50 minutes depending on traffic — use the official prepaid counter or a ride-hailing app rather than touts.
