Fly Singapore to Vietnam: Scoot, AirAsia, or VietJet in 2026

Vietnam is one of Singapore's fastest-growing outbound markets in 2026. Ho Chi Minh City, Hanoi, and Da Nang all pull steady demand for beach breaks, food-focused city trips, and cross-border business travel. Phu Quoc keeps gaining as a beach alternative to Bali and Phuket. Scoot, AirAsia, and VietJet dominate the low-cost side of these routes; here is how they compare on price, add-ons, reliability, and network in 2026.

The verdict

For most Singapore-to-Vietnam travellers in 2026, Scoot is the strongest all-round choice on price, on-time record, and direct-route network across HCMC, Hanoi, and Da Nang. AirAsia is cheapest on Da Nang and select shoulder-month HCMC dates via a KL layover, worthwhile if the 4 to 8 hour transit tolerance suits you. VietJet posts the sharpest headline fares but total cost with bags and seat frequently catches up to Scoot; the on-time record is the weakest of the three. Phu Quoc needs a Ho Chi Minh City connection on any of the three (or a direct via Vietnam Airlines / Bamboo Airways for a fare premium). Fares are cheapest in September to November and again from mid-January to mid-March, avoiding Lunar New Year peaks and Vietnamese school holiday windows.

Base fare by route

Sample base fares below are one-way, economy, checked mid-July 2026 for shoulder-month departures (October and February 2026-2027) 4 to 8 weeks out. Actual fares move daily and by season.

Route	Scoot	AirAsia (direct or KL layover)	VietJet
SIN to Ho Chi Minh City (SGN)	SGD 105 to 175 direct	SGD 90 to 165 direct; SGD 75 to 140 via KUL	SGD 90 to 160 direct
SIN to Hanoi (HAN)	SGD 130 to 220 direct	SGD 110 to 200 via KUL (few direct slots)	SGD 105 to 195 direct
SIN to Da Nang (DAD)	SGD 145 to 245 direct (limited days)	SGD 105 to 190 via KUL	SGD 130 to 230 direct
SIN to Phu Quoc (PQC)	Via SGN, connecting on Vietnam Airlines or VietJet, SGD 240 to 400 total one-way	Via KUL and SGN, SGD 220 to 380 total one-way	Direct SIN-PQC unavailable most days in 2026; VietJet HAN-PQC or SGN-PQC domestic segments common

Route-by-route notes. SIN-SGN is the most competitive route in the trio; all three airlines run daily direct flights. SIN-HAN Scoot direct is the flagship direct option; VietJet also runs direct. AirAsia typically routes SIN-HAN via KUL, adding 4 to 8 hours to the journey. SIN-DAD direct is thinner; Scoot runs limited-day direct, VietJet runs direct, AirAsia via KUL is the most common route. Phu Quoc has no reliable direct from Singapore in 2026; connect through SGN or HAN.

Total cost with bags and seat

Base fare is only half the picture on low-cost carriers. Ancillary revenue (checked bag, seat selection, meal, priority) makes up a growing share of total ticket cost. Here is how the three compare for a fully-loaded one-way ticket including 20kg checked bag, standard seat selection, and one meal:

Element	Scoot (economy)	AirAsia	VietJet
Base fare (SIN-SGN one-way, shoulder)	SGD 110 to 170	SGD 90 to 160	SGD 90 to 155
Cabin bag included	10kg (2 pieces incl. small item)	7kg	7kg
20kg checked bag add-on	SGD 30 to 50	SGD 25 to 55	SGD 30 to 60 (can spike closer to departure)
Standard seat selection	SGD 8 to 20 (extra-legroom higher)	SGD 8 to 22	SGD 6 to 20
Meal add-on	SGD 12 to 20	SGD 8 to 15	SGD 8 to 15
Priority boarding	Optional SGD 12 to 20	Optional SGD 8 to 15	Optional SGD 8 to 15
Fully-loaded one-way total	SGD 165 to 275	SGD 130 to 265 (higher if KUL layover requires overnight)	SGD 130 to 265

Where Scoot pulls ahead: 10kg cabin allowance is meaningful for short trips (2 to 4 nights) where a 10kg cabin bag can replace a checked bag entirely, saving SGD 30 to 50. Where AirAsia and VietJet pull ahead: raw base fare on shoulder-month bookings is 10 to 20% below Scoot. Where VietJet slips: bag add-on pricing has been volatile through 2025 to 2026, and last-minute bag adds at the airport can cost 2 to 3x the online price.

On-time performance

Based on publicly reported industry data covering 2025 to first half 2026:

Scoot. 75 to 82% on-time arrival on Vietnam routes (within 15 minutes of scheduled time). Scoot benefits from Changi's operational reliability at origin and typically well-managed slots at SGN, HAN, and DAD. Weather-related delays during Northeast monsoon (November to February) affect Hanoi and Da Nang more than Ho Chi Minh City.

AirAsia. 68 to 78% on-time depending on route. Direct SIN-SGN is closer to 75%. KL layover routes are lower (65 to 72%) because they inherit KUL Terminal 2 congestion and the risk of missed connections on tight layovers. AirAsia's reliability improves on early morning departures and degrades through the day as cascading delays build.

VietJet. 60 to 72% on-time on international routes in 2025 to 2026. VietJet has invested in fleet expansion and slot punctuality over the past 18 months, but the ranking still sits below Scoot and AirAsia. Domestic Vietnam segments (SGN-HAN, SGN-DAD, SGN-PQC) have historically been more delay-prone than international.

For a business trip, tour connection, or hotel with a tight check-in window, Scoot is the safest pick. For flexible travel where a 1 to 3 hour delay is workable, VietJet's fare saving may justify the reliability trade-off.

Best route for Phu Quoc

Phu Quoc (PQC) does not have a reliable direct flight from Singapore in 2026. Options:

Via Ho Chi Minh City (SGN). Fly Singapore to SGN on Scoot, AirAsia direct, or VietJet direct. Connect at Tan Son Nhat to a domestic SGN-PQC segment on Vietnam Airlines, VietJet, or Bamboo Airways. Domestic segment runs 55 minutes; total journey Singapore to Phu Quoc is roughly 6 to 9 hours including layover. Domestic Vietnam segment cost SGD 60 to 130 one-way.

Via KL and Ho Chi Minh City. AirAsia SIN-KUL-SGN, connecting to a domestic SGN-PQC. Longer total journey (9 to 13 hours) but sometimes the cheapest total when AirAsia has a KL sale. Requires separate ticket for the SGN-PQC leg or booking via a single OTA that handles multi-carrier.

Via Hanoi (HAN). Less common for Singapore origins because HAN-PQC is a longer domestic segment than SGN-PQC. Only makes sense if you are already planning a Hanoi stop.

Direct via Vietnam Airlines or Bamboo Airways. Vietnam Airlines has run seasonal SIN-PQC direct in prior years. Check current schedule; if operating, direct is the fastest but priciest option (typically SGD 380 to 550 round trip).

For Phu Quoc-only trips, the sharpest path in 2026 is Scoot or VietJet direct to SGN, then VietJet or Vietnam Airlines domestic to PQC, booked as one itinerary via Trip.com or Traveloka to preserve missed-connection protection.

When fares drop across the year

Vietnam route fares from Singapore follow four seasonal cycles:

Cheapest windows.

• Late September to early November: end of school holidays, low rainfall (in the south), fewer Vietnamese domestic travellers. Base fares 15 to 25% below the annual mean.
• Mid-January to mid-March, avoiding Tet (Vietnamese Lunar New Year, late January to early February 2027): school-holiday-lite period after the New Year rush. Base fares 10 to 20% below annual mean.
• Early May (post-Labour Day, pre-summer): brief soft window before the June to August peak. 10 to 15% below annual mean.

Priciest windows.

• Late December to early January (Christmas and Western New Year): fares peak 30 to 60% above annual mean.
• Tet week (late January to early February 2027 for the upcoming year): Vietnam-origin demand pushes fares up 40 to 80%. Also disruption risk from domestic flight congestion.
• June to August: Singapore school holidays plus Vietnamese school holidays. Peak season. 25 to 45% above annual mean.
• NDP long weekend and Vesak Day cross-region weekends: brief spikes of 15 to 25% for the specific window.

Booking window. For shoulder months, fares typically bottom 6 to 10 weeks out. Inside 3 weeks, all three airlines mark up 20 to 35% on all Vietnam routes. Peak-season bookings should be locked 12 to 20 weeks out.

What this means in practice

A Singapore couple planning a 5-day HCMC food trip in October 2026 should target Scoot direct SIN-SGN. Book 6 to 8 weeks out at shoulder-window prices (SGD 130 to 150 one-way base fare). Add 20kg checked bag on outbound only (SGD 35), skip meal (buy at Changi lounge or on arrival), standard seat selection (SGD 12 one-way). Fully-loaded round-trip lands around SGD 320 to 380 per person. Book hotel via Trip.com or Agoda, airport transfer via Klook.

A Singapore solo traveller on a 10-day Vietnam trip covering HCMC and Hanoi in February 2027 (post-Tet), on tightest possible budget, should target VietJet direct SIN-SGN and Vietnam Airlines SGN-HAN domestic, returning VietJet HAN-SIN. Base one-way SGN roughly SGD 100, domestic SGN-HAN SGD 55, one-way return HAN-SIN SGD 120. Total flight cost around SGD 275 plus bags SGD 35 to 55. On-time delay risk is real but a 10-day trip absorbs it.

A Singapore family of four planning a Da Nang beach and Hoi An culture trip during June school holidays should target AirAsia SIN-KUL-DAD. Direct SIN-DAD is thinly served and peak-season prices are high (SGD 260 to 340 one-way per person direct). AirAsia KL layover route can drop base one-way to SGD 180 to 240 per person, saving SGD 320 to 400 for the family. The 4 to 8 hour KUL layover is manageable with kids if you plan lounge access or a short city visit.

When this does NOT apply

• You are booking Vietnam Airlines or Bamboo Airways specifically. Neither is a low-cost carrier; different fare structure and service model applies. Vietnam Airlines is often the best full-service option for direct Phu Quoc.
• You have credits or vouchers from a previous booking. Use the credit on the same carrier before comparing fares.
• You are on a business travel policy. Corporate T&E policies often mandate full-service or specific carriers; scope this before applying the LCC comparison.
• You are flying with a KrisFlyer status or accumulating miles. Scoot is not part of Star Alliance but does have KrisFlyer partnership; check the current earning rate before optimising against total cost.
• The route is highly time-critical. For an urgent trip, Singapore Airlines full-service is often the best schedule choice despite higher fare.
• You are combining with cruise or overland travel. Multi-modal itineraries change the calculus; single-flight optimisation may not apply.
