Here are the key facts for Singapore to Hanoi flights.

How long does it take to fly from Singapore to Hanoi?

Direct flight duration

• Direct flights from Singapore Changi (SIN) to Hanoi Noi Bai (HAN) take approximately 3 hours 30 minutes (Kayak).
• The fastest recorded direct flight is 3 hours 15 minutes (Momondo).

Including layovers

• Layover flights via Kuala Lumpur, Bangkok, or Ho Chi Minh City can take 6–12 hours, depending on stopover duration.
• Direct flights average $242 round-trip, often cheaper than itineraries with connections (Kayak).

The pattern: a direct flight means you trade two or three hours of travel time for a higher base fare. For a weekend trip, the extra cost is usually justified — you arrive same day with no jetlag.

What’s the cheapest month to fly to Hanoi?

Seasonal price trends

Prices swing substantially by season. Here is a snapshot of monthly averages for round-trip Singapore–Hanoi fares:

Six months, one pattern: demand drives the price — avoid peak European summer and Tet holiday.

Tips for finding cheap flights

• Use fare alerts on Skyscanner or Kayak for real-time tracking.
• Book 6–8 weeks before departure for best domestic pricing on budget carriers.
• Compare total costs including baggage and meals — Vietnam Airlines’ base fare often includes them.

The trade-off: flying in March or September saves up to $113 compared to December. But if your schedule is fixed, the consolation is that even peak-season fares on this route rarely exceed $300 round-trip.

Which airlines fly to Vietnam from Singapore?

Full-service carriers

• Singapore Airlines: 18 weekly direct flights, average $286 round-trip (Momondo). Meals, entertainment, and 30 kg checked baggage included.
• Vietnam Airlines: Full-service national carrier; base round-trip from $207 (Momondo). Includes meals and 23 kg baggage.

Budget airlines

• Scoot: Lowest one-way fare $59 (Skyscanner), round-trip from $137 (Momondo). Add $25–$50 each way for luggage and seat selection.
• VietJet Air: Round-trip from $166 (Momondo). Charge for baggage and meals.

Three carriers, one decision: base fare tells only half the story — Vietnam Airlines’ inclusive ticket often ends up matching or beating Scoot plus add-ons.

The implication: for a traveler checking only the base fare, Scoot looks unbeatable. But once you add 20 kg checked baggage and a hot meal (approximately $50 round-trip), Vietnam Airlines becomes the cost-equal value champion — particularly on longer stays where baggage matters.

How to travel from Singapore to Hanoi?

By air

• Flying is the fastest and most common method. Direct flights depart from Changi Airport (SIN) to Noi Bai Airport (HAN) daily (Kayak).

Alternative routes (overland, train)

• Overland via Thailand or Malaysia is possible but takes 2–3 days, impractical for a short trip.

Visa requirements

• Singapore passport holders can enter Vietnam visa-free for up to 30 days (Kayak).
• E-visa available for other nationalities; processing takes 3–5 business days (Skyscanner).

The pattern: for most travelers, flying is the only practical choice. The real decision is whether the extra cost of a direct flight buys enough time to make your trip feel longer.

What’s the best time to visit Vietnam?

Hanoi weather by season

• March–April: Spring, mild 20–25°C, low rainfall — ideal for city walks and Ha Long Bay trips (Kayak).
• October–November: Autumn, dry and clear — prime time for photography (Skyscanner).

Avoiding rainy months

• June–August: Heavy rain, typhoon risk, high humidity. Less popular for outdoor activities (Kayak).
• December–February: Cool (10–20°C) and dry — pleasant but pack a jacket.

The catch: the two “best” windows also coincide with peak demand from European tourists. You get better weather but pay slightly more — March–April round-trip fares average $171 (Skyscanner), while peak June–August averages $221 (Kayak).

For a traveler from Singapore, the choice comes down to trip length and luggage needs. A weekend with only a backpack: Scoot, $59 one-way, no frills. A week exploring Hanoi and Ha Long Bay: Vietnam Airlines at $170 round-trip with meals and bags included. The decision is clear: cheap headline or total cost.
