SINGAPORE— Singapore Airlines (SQ) will increase flights to Ho Chi Minh City and Da Nang from October 25, 2026, as it expands its Vietnam schedule for the northern winter 2026/27 season.
The airline will add a fourth daily service between Singapore Changi Airport (SIN) and Ho Chi Minh City’s Tan Son Nhat International Airport (SGN), while the Da Nang (DAD) route will rise to three daily flights.
The changes will take SIA’s Vietnam operation to 70 weekly flights, including 28 to Ho Chi Minh City, 21 to Da Nang and 21 to Hanoi.
However, the increase will affect the two routes differently, with Da Nang receiving a straightforward capacity boost while Ho Chi Minh City will gain frequency but lose some overall seat capacity.
Singapore Airlines’ Ho Chi Minh Flights
The new Ho Chi Minh City service will operate as SQ188 from Singapore at 9:50 p.m., arriving in the Vietnamese city at 11 p.m.
Its return flight, SQ187, will leave Ho Chi Minh City at 5:55 a.m. and reach Singapore at 9:05 a.m., giving passengers a new early-morning option.
Both flights will use the Boeing 737-8 MAX, which has 154 seats. At the same time, SIA will replace the Boeing 787-10 currently assigned to SQ178/177 with another 737-8 MAX, reducing the number of seats available despite the additional daily frequency.
The route will therefore increase from 21 to 28 weekly flights, or 33%, but weekly seat capacity will fall from 6,489 to 6,286.
Business Class capacity will decline more sharply, dropping from 798 to 686 seats, a 14% reduction.
Da Nang’s Increased Capacity on the 737-8
SIA will add SQ176/SQ175 to its Da Nang schedule, taking the route from two to three daily flights.
The new Singapore departure will leave at 5 p.m. and arrive in Da Nang at 6:45 p.m., while the return service will depart at 7:35 p.m. and reach Singapore at 11:35 p.m.
Unlike Ho Chi Minh City, the Da Nang expansion will directly increase capacity because all three daily services will use the Boeing 737-8 MAX.
Weekly flights will rise from 14 to 21, while total seats will increase from 2,156 to 3,234, representing a 50% gain.
Singapore Airlines’ Vietnam Network Expands
The changes follow SIA’s decision to increase Singapore-Hanoi flights from two to three daily in June 2026.
The third Hanoi service will remain in place during the 2026/27 winter season, giving the airline 21 weekly flights on the route.
SIA’s expanded schedule will put its Vietnam operation well above its pre-pandemic frequency.
In December 2019, SIA operated 19 weekly flights to Ho Chi Minh City and 14 to Hanoi, while SilkAir operated 11 weekly flights to Da Nang, Mainly Miles flagged.
The additional services are currently scheduled through March 27, 2027, with the regular summer schedule beginning the following day.
Singapore Airlines has also stated that flight schedules remain subject to change.
