Where the price variation comes from

Three structural drivers set SIN-HAN fare pricing across the year.

Weather and tourist season. Hanoi's peak tourist season is October to December (cool, dry, 17 to 25 degrees Celsius) and pricing tracks this. Once October arrives, both Singapore-outbound and inbound-from-North-Asia demand climbs; carriers hold fares higher. Monsoon (June to August, peaks July to August) is the low season; carriers discount to fill.

Vietnamese diaspora holidays. Tet (Lunar New Year, late January to mid-February) is Vietnam's biggest annual holiday. Vietnamese working in Singapore, Malaysia, and Hong Kong all return home in the same 10-day window. Fares spike SGD 200 to 400 above baseline for Tet week specifically. Vietnam Airlines and VietJet run maximum-frequency schedules; even so, seats sell out 3+ months ahead.

Singapore school holidays. June to July (mid-year break) and mid-November to December (year-end break) both lift SG-outbound demand. June-July HAN pricing typically runs SGD 380 to 560 return, versus September SGD 220 to 380. Same route, same seat, SGD 160+ delta from school-holiday pressure alone.

The Vietnam Airlines SIN-HAN route page shows fare buckets that shift by up to 60 percent between shoulder and peak windows. The full-service carrier premium (Vietnam Airlines and Singapore Airlines) over low-cost (Scoot, VietJet, Jetstar Asia) is typically 30 to 50 percent on the same date and time slot.

What airlines actually fly SIN to HAN in 2026

Carrier	Type	Typical return fare band (SGD)	Notes
Scoot (TR)	Low-cost	220 to 480	2 to 3 daily; checked-bag USD 25 to 40 extra
VietJet Air (VJ)	Low-cost	230 to 500	2 to 3 daily; overnight departure available
Jetstar Asia (3K)	Low-cost	260 to 540	Schedule reduced post-2025 restructure
Singapore Airlines (SQ)	Full-service	380 to 780	2 daily; bag and meal included
Vietnam Airlines (VN)	Full-service	340 to 700	2 daily; bag and meal included; SkyTeam

Scoot has historically been the cheapest low-fare leader on the route. VietJet often matches within SGD 10 to 30 on the same dates. Vietnam Airlines and Singapore Airlines maintain a 30 to 50 percent premium for full service and SkyTeam or KrisFlyer miles. As of 2026-09-14, Jetstar Asia schedules on the route have thinned; verify current schedule before booking.

Note on legacy carriers: Jetstar Asia (Singapore-based, not the Australian Jetstar Airways parent) has undergone route restructuring. Bamboo Airways, which historically ran SIN to HAN, has suspended most international operations. Verify with direct-airline sites for real-time schedules.

What authoritative sources say

Skyscanner's route-page analysis notes that "the cheapest month to fly from Singapore Changi to Hanoi is usually August," and identifies specific low-fare dates such as Thursday, August 27, 2026. Momondo, aggregating fare data across the route, says "the cheapest month to fly is August" as well. The consensus from three separate fare aggregators is that August-September consistently wins.

Skyscanner also notes that "Tuesday is usually the cheapest day to fly from Singapore to Hanoi, with potential savings of up to 15 percent compared to peak travel days." This aligns with global airline yield-management practice: leisure demand concentrates Thursday to Sunday; Tuesday and Wednesday clear inventory below.

Per Skyscanner: "cheaper fares are usually found when booking at least two months in advance." Vietnamese Tet fares and Christmas fares typically hit their peak 6 weeks before travel and rarely drop below that peak in the final 4 weeks.

Use case segmentation

Match your travel window to your priority.

For the cheapest possible fare (backpacker, budget solo): book August or September mid-week (Tuesday or Wednesday), 6 to 10 weeks ahead, Scoot or VietJet. Target under SGD 260 return. Add Ha Long Bay day cruise via Klook (SGD 55 to 110).

For the "cool and dry Hanoi weather" window: October or early November. Fares run SGD 260 to 460, weather is peak (17 to 25 degrees Celsius). Book 2 to 3 months ahead. This is the most-tourist-crowded window.

For a Chinese New Year escape (avoid Tet week itself): Late February or early March. Post-Tet fares dip to SGD 280 to 460, weather is transitioning from cold-damp to warming. Skip Tet week; skip late January to mid-February entirely.

For Singapore school-holiday families: Late June or early July if you must, but expect SGD 380 to 560 return. Consider late August instead (still school holiday tail-end for some, and SGD 100 to 200 cheaper).

For miles collectors: Singapore Airlines (KrisFlyer) or Vietnam Airlines (SkyTeam) full-service. Pay the SGD 100 to 350 premium for lounge, bag, and miles. Route-earn per USD spent is roughly 1.5 to 2x low-cost carrier value.

Use ShopBack Travel Planner to compare Skyscanner, Trip.com, Agoda Flights, and direct-airline on the same dates.

When these numbers do NOT apply

• Tet week itself (roughly Jan 25 to Feb 15 depending on year). Fares spike SGD 200 to 400 above January baseline. Book 4+ months ahead or skip.
• Christmas Eve or New Year's Day travel dates. Same-week departure from Dec 22 to Jan 3: expect SGD 100 to 250 premium above stated month averages.
• Multi-city itineraries via HAN (Hanoi as a transit to Sapa, Ha Long, or onward Northern Vietnam). Domestic add-ons run SGD 60 to 180 per leg on VietJet or Vietnam Airlines.
• Public holiday long weekends in Singapore (Deepavali, Hari Raya, National Day, Chinese New Year). Add 15 to 30 percent to stated fares. Book 3+ months ahead.
• Award tickets on Singapore Airlines KrisFlyer. Different pricing model; check KrisFlyer award chart. HAN is a Zone 3 destination; roughly 17,500 miles one-way in economy saver.

Practical booking tips

Five tactical moves to actually book at the cheap end of these ranges.

1. Set a Skyscanner price alert for your exact dates. Alerts fire when Scoot or VietJet drop fares (typically once every 2 to 4 weeks in shoulder season).
2. Compare Skyscanner + Trip.com + Agoda Flights on the same day. Different aggregators contract different fare buckets. Save an extra SGD 20 to 60 per person by finding the aggregator with the best inventory for your dates.
3. Fly Tuesday or Wednesday out; return Tuesday or Wednesday. Weekend flights are 10 to 15 percent more expensive on the same route (Skyscanner's own data).
4. Book at least 8 weeks ahead for peak windows (Dec to Feb), 4 to 6 weeks ahead for shoulder. Fare drops in the final 2 weeks are rare on SIN-HAN because both carriers are yield-managed.
5. Activate ShopBack via the extension before checkout. Book on the merchant page that has current cashback listed on the ShopBack Singapore travel category.
