Singapore to Hanoi is a short, well-served hop into northern Vietnam — the capital’s Old Quarter, plus the launch pad for Ha Long Bay and Sapa. Four airlines fly it non-stop in under three and a half hours, giving a healthy mix of full-service and budget fares. This guide covers who flies the route, what a fair return costs in Singapore dollars, and when to book.
Route: Singapore Changi (SIN) → Hanoi Noi Bai (HAN)
Distance: approximately 2,190 km (1,360 miles)
Non-stop flight time: about 3h 25m
Direct flights: Yes — Singapore Airlines, Vietnam Airlines, Scoot and Vietjet all fly non-stop. One-stop itineraries exist but rarely beat the non-stops on this route.
Fares from Singapore to Hanoi (SGD)
Northern Vietnam has a real winter: the cool, dry months from October to April are the most popular (and pricier), while summer is hot, humid and cheaper. The biggest spikes are the Christmas/New Year weeks and, crucially, Tết (Vietnamese Lunar New Year, late January or February), when fares and demand jump. 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 (Tết) |
| February | — | high (Tết) |
| March | — | medium |
| April | — | medium |
| May | — | low |
| June | — | low-medium (school holidays) |
| July | — | medium |
| August | — | medium |
| September | — | low |
| October | — | medium-high |
| November | — | medium-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We do not quote a target fare for this route.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 3½ hours):
- Singapore Airlines — the most frequent non-stop, from Changi Terminal 3; full-service with baggage and meals included.
- Vietnam Airlines — the flag carrier’s daily non-stop, with easy onward links to Da Nang, Hue and beyond.
- Scoot — a low-cost non-stop several days a week; bags and seats are extra.
- Vietjet — Vietnam’s big budget carrier, usually a competitive headline fare on the route.
One-stop (rarely cheaper here):
- AirAsia via Kuala Lumpur or Bangkok — occasionally undercuts the non-stops, but adds hours to the trip.
- Regional carriers via a Southeast Asian hub — only worth it if the timing or price is clearly better.
With four non-stop carriers competing, there is little reason to take a connection on this route — the direct flights are short and usually well-priced. Pick a full-service non-stop if you want baggage and meals included, or a budget non-stop if you are travelling light and want the lowest fare.
When to book & how to save
- Book 6–10 weeks ahead for the best short-haul fares; around Tết and Christmas, book 2–3 months out.
- Avoid Tết (Vietnamese Lunar New Year, late January/February) and Christmas/New Year — the busiest and dearest windows, when many services fill up.
- Travel in the low season (May, September) for the cheapest fares; summer is hot and humid in Hanoi but the flights are cheap.
- Go non-stop: with four direct carriers, a connection rarely saves money and always costs time.
- Watch the extras on Scoot and Vietjet: the base fare excludes checked bags and seats, so add those when comparing against Singapore Airlines or Vietnam Airlines.
Arriving in Hanoi
Flights land at Noi Bai International Airport (HAN), about 27 km north of the city; international flights use Terminal 2. The cheapest way into town is the public express bus (routes 86 or 68) to the Old Quarter for around VND 35,000–45,000 (about S$ 2), taking 45–60 minutes. A metered or app-based taxi to the centre costs roughly VND 300,000–400,000 (around S$ 16–22) and takes 30–45 minutes — agree the fare or use a ride-hailing app to avoid overcharging.
Frequently asked questions
How long is the flight from Singapore to Hanoi?
The non-stop flight takes about 3 hours 25 minutes. Because four airlines fly the route directly, a one-stop itinerary is rarely worth it — connections through Kuala Lumpur or Bangkok can stretch the journey to 7 to 12 hours in total.
Are there direct flights from Singapore to Hanoi?
Yes. Singapore Airlines, Vietnam Airlines, Scoot and Vietjet all fly non-stop between Changi and Hanoi. With that much competition, the direct flights are frequent and usually well-priced, so most travellers fly non-stop.
How much does it cost to fly from Singapore to Hanoi?
A typical economy return runs about S$ 220–S$ 500 depending on the season and airline. The best budget deals dip to around S$ 210–S$ 250 in the low season (May, September), while Tết and December sit at the top of the range.
What is the cheapest month to fly from Singapore to Hanoi?
May and September are usually the cheapest months to fly. Avoid Tết (Vietnamese Lunar New Year in late January or February) and the December Christmas peak, which are the busiest and most expensive.
Which airlines fly from Singapore to Hanoi?
Four carriers fly non-stop: Singapore Airlines and Vietnam Airlines (full-service, baggage included) and Scoot and Vietjet (low-cost, extras added). Vietjet usually has a competitive headline fare; Singapore Airlines is the most frequent.
Which airport do I fly into in Hanoi?
All flights use Noi Bai International Airport (HAN), Hanoi’s main airport about 27 km north of the city. International services arrive at Terminal 2, which connects to the centre by express bus and taxi in around 30–60 minutes.
How far in advance should I book Singapore to Hanoi flights?
Aim to book 6 to 10 weeks ahead for the best short-haul fares. For Tết (Vietnamese Lunar New Year) and the Christmas/New Year peak, book 2 to 3 months out, as flights fill up and fares climb sharply.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) are usually a little cheaper than Friday–Sunday, and flying out and back on weekdays can save S$ 20–S$ 60 on a return. Shifting your dates by a day or two is one of the easiest ways to trim the fare.
