Singapore Airlines will add more flights to two of its three Vietnam destinations from the start of the northern winter 2026/27 season on 25th October 2026, with Ho Chi Minh City stepping up to four daily services for the first time, and Da Nang increasing from two to three daily flights.
Both hikes are seasonal for now, with schedules reverting to the regular pattern (3x daily to Ho Chi Minh City, and 2x daily to Da Nang) from the start of the northern summer 2027 season on 28th March 2027. As always though, schedules that far out remain subject to change, so we’ll keep an eye on whether these extra flights stick around.
Additionally, while the headline suggests a big capacity boost on both routes, that’s only really true for Da Nang. On the Ho Chi Minh City route, one extra flight actually means fewer seats overall due to some aircraft juggling, with quite a lot fewer in Business Class.
Ho Chi Minh City: four daily flights, but fewer seats
Singapore Airlines currently operates three daily flights to Ho Chi Minh City (SGN), all using widebody aircraft – one Airbus A350 Long Haul and two Boeing 787-10s.
From 25th October 2026, a fourth daily service will be added using a Boeing 737-8 MAX, with a late night departure from Changi and an early morning return.
- SQ188 departs Singapore at 9.50pm, arriving in Ho Chi Minh City at 11pm local time
- SQ187 departs Ho Chi Minh City at 5.55am, arriving back in Singapore at 9.05am
The aircraft will stay overnight in Ho Chi Minh City between the two flights, which is how the new early morning timing from Tan Son Nhat comes about.
Predominantly, this allows SIA to tap into the market for Vietnam-based travellers wanting a full day in Singapore, or those connecting onto the airline’s lunchtime departures from Changi. It’s unlikely to appeal to most of our readers returning from a few days in Saigon.

At the same time though, one of the existing widebody rotations (SQ178/177) will be downgauged from a Boeing 787-10 to a Boeing 737-8 MAX for the winter season.
Here’s how the four daily services will then be operated.

| SQ186/185 | Boeing 787-10 | Boeing 787-10 |
| SQ188/187 | – | Boeing 737-8 MAX (new) |
The Boeing 737-8 MAX seats 154 passengers, compared to 337 on the Boeing 787-10, so replacing one 787-10 rotation with the smaller jet more than cancels out the extra seats from the new fourth flight (yes, SIA really packs in passengers on its 787-10s!).
The result is that while weekly flights rise by 33%, from 21 to 28, total weekly seat capacity actually falls by 3%, from 6,489 to 6,286.
The impact is more pronounced in Business Class. The 737-8 MAX has just 10 Business Class seats, versus 36 on the 787-10, so weekly Business Class capacity on the route drops from 798 seats to 686 seats, a 14% reduction.

| Total seats | 6,489 | 6,286 | 3% |
* Sold as Economy Class on this route, with the option to select these seats for an additional fee
There is some good news for premium travellers, with the daily A350 Long Haul service (SQ184/183) remaining in place.
That means the 2013 Business Class product is still available on the route once a day, while the Premium Economy cabin can also still be selected for an additional fee by passengers booked in Economy (free for PPS Club members) – though there’s no Premium Economy service as such on board.
On the other flights, you’ll find the airline’s flat-bed regional Business Class seats, either the 2018 Regional Business Class on the 787-10, or the 737-8 MAX version with its much smaller 10-seat cabin.
Low-cost subsidiary Scoot will continue to operate three daily flights between Singapore and Ho Chi Minh City this winter, using Airbus A320neo and A321neo aircraft, so overall group capacity remains largely unchanged.
In terms of non-SIA Group options, the Singapore – Ho Chi Minh City route is also served by VietJet and Vietnam Airlines.

Da Nang: three daily flights, 50% more seats
The Da Nang (DAD) increase is much more straightforward. The route is already served twice daily by the Boeing 737-8 MAX, and from 25th October 2026 a third daily flight will be added using the same aircraft type.
The new flight is an afternoon turnaround service:
- SQ176 departs Singapore at 5pm, arriving in Da Nang at 6.45pm local time
- SQ175 departs Da Nang at 7.35pm, arriving back in Singapore at 11.35pm
Since all three flights use the same aircraft type, this is a simple frequency and seat capacity hike of 50% across all cabins.

| Total seats | 2,156 | 3,234 | 50% |
Scoot will also continue to fly daily to Da Nang this winter with its Airbus A320neo and A321neo aircraft, apart from on a handful of dates in early November 2026. That means the extra SIA flight is an overall capacity increase for the group as a whole in this market.
Outside the SIA Group, VietJet also operates direct flights between Singapore and Da Nang.

– New flights
What about the rest of Vietnam?
Hanoi is Singapore Airlines’ only other destination in Vietnam, and it has already seen a frequency boost this year, moving from two to three daily flights in June 2026, as we reported back in January.
That third daily Hanoi flight will be retained through the northern winter 2026/27 season, which represents a 50% frequency increase compared to the same period last year.
In Vietnam, Scoot also serves Nha Trang three times weekly and Phu Quoc eight times weekly using Embraer E190 aircraft. This winter season sees Phu Quoc scaling up to the larger Airbus A320 with daily flights, a 40% capacity hike on the route.
A big step up from pre-COVID
These upcoming changes mean Singapore Airlines will operate 70 weekly flights to Vietnam this winter – 28 to Ho Chi Minh City, 21 to Da Nang and 21 to Hanoi.
In December 2019, Singapore Airlines operated 19 weekly flights to Ho Chi Minh City, and 14 times weekly to Hanoi, while regional subsidiary SilkAir flew 11 times weekly to Da Nang.
That’s a 59% increase in Singapore Airlines flights to and from the country as a whole compared to the combined SIA / SilkAir operation back then, based on flight frequencies alone.
This winter, the Ho Chi Minh City frequency is almost 50% higher than it was back then, while Da Nang flights have nearly doubled compared to the SilkAir era (albeit with a similarly-sized narrow-body aircraft, now with flat-bed Business Class seats).

Summary
Singapore Airlines’ two Vietnam increases this winter look similar, with an extra daily flight each to Ho Chi Minh and Da Nang, but they actually play out quite differently.
Da Nang is a clear-cut win, with a third daily Boeing 737-8 MAX flight lifting capacity by 50% in every cabin, while Scoot maintains its own daily service alongside.
Ho Chi Minh City, on the other hand, gets a fourth daily flight and a handy (for some) new early morning departure from Tan Son Nhat, but the simultaneous downgauge of one Boeing 787-10 rotation means there will actually be slightly fewer seats on the route overall than there are today, and notably 14% fewer in Business Class.
Fans of SIA’s larger long-haul Business Class seats can still count on the daily Airbus A350 LH service, but with more of the route now flown by the 10-seat 737-8 MAX cabin, Business Class award and upgrade availability could become tighter than before at peak times this winter.
Both increases are currently scheduled to end when the next northern summer season starts in late March 2027, so we’ll be keeping an eye on whether SIA decides to extend them.
