SINGAPORE- Singapore Airlines (SQ) will introduce a 7th daily flight between Singapore Changi Airport (SIN) and Bangkok Suvarnabhumi Airport (BKK) from March 2026, increasing capacity on its second-busiest route.
The additional service restores Airbus A350 Long Haul operations on selected days, offering the wider 2013 Business Class seat and a Premium Economy cabin sold as Economy Class.
Singapore Airlines 7th Daily Flight to Bangkok
Singapore Airlines has updated its finalised Summer 2026 schedule to include an extra daily Singapore–Bangkok rotation, taking total frequencies to 7 flights per day in each direction.
This enhancement comes just two months before the season begins and adds both capacity and schedule flexibility.
Reported by Mainly Miles, the new service also reintroduces the Airbus A350 Long Haul aircraft to the route on selected days, a configuration rarely deployed on this short sector.
The aircraft choice elevates the onboard experience for passengers able to align travel dates with the long-haul-equipped flights.
All services operate daily between 29 March 2026 and 24 October 2026, subject to aircraft variation by date.

Bangkok Remains Singapore Airlines’ Second-Busiest Route
Bangkok continues to rank as Singapore Airlines’ second-busiest destination by weekly seat capacity. The additional daily frequency further strengthens this position.
Busiest Singapore Airlines Routes by Weekly Seat Capacity (July 2026)
| Rank | City | Weekly Seat Capacity | Change vs March 2026 |
|---|---|---|---|
| 1 | Jakarta | 17,143 | +6 percent |
| 2 | Bangkok | 16,177 | +16 percent |
| 3 | Bali | 14,154 | +22 percent |
| 4 | London | 11,984 | +1 percent |
| 5 | Hong Kong | 11,081 | +17 percent |
With this expansion, Bangkok narrows the gap with Jakarta as the airline’s busiest route overall.
Airbus A350 and Business Class Seat
On days operated by the Airbus A350 Long Haul, passengers can access Singapore Airlines’ 2013 Business Class product.
Each aircraft features 42 Business Class seats with direct aisle access and the widest seat currently offered by the airline on the Bangkok route.
These seats supplement the 2018 Regional Business Class found on the A350 Medium Haul and Boeing 787-10.
While newer, the regional seat is narrower, and some passengers find it restrictive for comfort-sensitive travel.
For travellers flying on Tuesdays, Thursdays, Saturdays, or Sundays, selecting SQ722 or SQ721 provides a rare opportunity to experience the long-haul Business Class cabin on a short regional flight.
Future Long-Haul Business Class Developments
Singapore Airlines plans to introduce a new closed-door, suite-style Business Class on the Airbus A350 Long Haul from the second quarter of 2026.
The airline intends to complete the retrofit programme across the fleet by the end of 2030, although such timelines have historically slipped.
While Bangkok is technically a candidate for the new seat due to aircraft rotation efficiency, it is unlikely to be an early recipient given competing long-haul priorities such as London.
Passengers are therefore advised not to book SQ722 or SQ721 solely in anticipation of this future product.
Premium Economy Sold as Economy Class
The Airbus A350 Long Haul features a 3-class layout, including Premium Economy. On Singapore–Bangkok flights, these seats are sold as Economy Class, with passengers able to pay a seat selection fee for additional space but without enhanced service.
Premium Economy seat features include:
- 38-inch seat pitch
- 19-inch seat width
- 8-inch recline
- 2-4-2 seating layout
- 13.3-inch HD touchscreen
- Calf rest and footrest
- Two USB ports and AC power
- Adjustable reading light
The 2-4-2 configuration allows paired window seating, which is unavailable in standard Economy.
Premium Economy Seat Selection Fees
Seat selection fees apply regardless of the Economy fare type or award redemption.
(Economy Class passengers on selected Bangkok flights)
| Passenger Status | Standard Seat Fee | Extra Legroom Seat Fee |
|---|---|---|
| Non-KrisFlyer | US$30.00 | US$50.00 |
| KrisFlyer Basic | US$28.50 | US$47.50 |
| KrisFlyer Elite Silver | US$27.00 | US$45.00 |
| KrisFlyer Elite Gold | US$25.50 | US$42.50 |
| PPS Club | Free | Free |
An alternative approach is to wait until online check-in opens exactly 48 hours before departure. At this point, all seat selection fees are removed, and Premium Economy seats may be selected for free, subject to availability.
Post check-in seat changes may require assistance from Singapore Airlines via phone or Kris chatbot.
KrisFlyer Award Redemptions
One-way KrisFlyer redemption rates between Singapore and Bangkok are as follows:
- Economy Class: 13,000 miles (Saver) or 27,500 miles (Advantage)
- Business Class: 25,000 miles (Saver) or 46,000 miles (Advantage)
Taxes and fees typically total around S$68 from Singapore to Bangkok and S$32 in the return direction.
Redemptions made from 1 April 2026 for travel on or after 1 October 2026 will also incur Singapore’s new Sustainable Aviation Fuel levy on this route.
Bottom Line
Singapore Airlines’ seventh daily Singapore–Bangkok flight represents a meaningful capacity increase on a critical regional route.
The new late-morning departure from Singapore and early-afternoon return from Bangkok add valuable scheduling flexibility.
The standout feature is the limited return of the Airbus A350 Long Haul with the 2013 Business Class seat on 4 days per week, offering a more spacious alternative to the standard regional configuration.
Premium Economy seating, while sold as Economy, provides additional comfort for those able to secure it.
With potential aircraft changes from late October 2026, travellers seeking this specific experience should plan accordingly.
