Singapore Airlines recently confirmed its flight schedules for the northern summer season from April 2026 through to October 2026, including days of operation and aircraft type allocation, which means it’s time for the latest update to our longstanding guide to the carrier’s onboard products in Business Class, by route and individual flight number.

SIA has already rebuilt its passenger seat capacity close to pre-pandemic levels, and this summer the carrier will operate around 91% of former flight volumes, compared to the pre-COVID combined SIA / SilkAir operation.

That means an almost full return to a healthy mix of aircraft types, routes and cabin products for the airline, including the latest flat-bed seats on the Boeing 737-8 MAX aircraft fleet, plus there will be an all-new long-haul Business Class seat in the mix later this year – though specific flights for that one are still under wraps for now.

Four Business Class seat types

While there were no new Business Class seat types added in 2025, we did finally say goodbye to the ex-SilkAir recliner seats in October last year thanks to the withdrawal of Boeing 737-800s from the fleet, which has seen SIA transition to an all-flat-bed Business Class era fleet-wide for the first time.

Since the pandemic we’ve also said goodbye to two other seat models in this cabin – the 2009 Regional Business Class and the 2006 Long Haul Business Class, but a new narrow-body product was introduced at the pointy end of Boeing 737-8 MAXs.

Here’s a summary of the four different Business Class seat types currently in use across the fleet.

Image	Seat Guide	Aircraft
2013 J	Here	Airbus A350 Long Haul (359 LH) Airbus A350 ULR (359 ULR) Boeing 777-300ER (77W)
2017 J	Here	Airbus A380 (388)
2018 RJ	Here	Airbus A350 Medium Haul (359 MH) Boeing 787-10 (787)
MAX RJ	Here	Boeing 737-8 MAX (7M8)

The airline is launching a new long-haul Business Class seat for the Airbus A350 LH and Airbus A350 ULR aircraft, due to start flying on selected flights from Q1 2027, so look out for a 2027 J cabin joining the list soon.

Notable changes for summer 2026

In many cases Business Class seat types for the summer 2026 season are a continuation of the current allocation for each city on the network, but there are a few notable changes or points of interest worth highlighting this year:

• Bali flights will transition to all-widebody operation for the summer season, with up to two of six daily flights currently using Boeing 737-8 MAX aircraft swapped out for the Boeing 787-10 from 29th March 2026, which means all-2018 RJ-seats whichever flight you choose.
• Bangkok gets a seventh daily flight (SQ722/721) from 29th March 2026, which sees the return of long-haul 2013 Business Class seats to the route four days per week (Tue, Thu, Sat, Sun), while the other three days of operation are on Boeing 787-10 aircraft with 2018 RJ seats.
• Colombo will see Boeing 737-8 MAX service on one of two daily flights from May 2026, when the city has its 10 times weekly service hiked to 14 times weekly.
• Dhaka will also start to receive the Boeing 737-8 MAX on its new second daily flight (SQ448/449) from August 2026, operating alongside daily Boeing 787-10 service (SQ446/447), with the new 737 rotation loaded in GDS but not yet available for booking at the time of writing.
• Delhi will see one of its two daily flights get the usual seasonal downgauge from an Airbus A380 to a Boeing 777-300ER between mid-June and late July 2026.
• Dubai will have its daily service upgraded to Airbus A380 aircraft from 29th March 2026, the first time the superjumbo and its 2017 J seats in Business Class have been used on the route. SIA has been trying to increase flights to Dubai for some time, but has struggled to obtain appropriate slots, so a capacity hike on the existing rotation seems to be the answer.

• Ho Chi Minh continues to get a consistent long-haul cabin product on daily SQ184/183 services, for those who prefer the 2013 Business Class seats even on a short hop.
• Hong Kong will see its daily four-class Boeing 777-300ER flight temporarily upgauged to the Airbus A380 from 21st June 2026 to 25th July 2026.
• Jakarta will receive regional cabin products on three of its nine daily flights during the summer season, a shift from the current 100% deployment of long-haul cabins on the carrier’s busiest route.
• Kuala Lumpur will have two daily flights operated by the Airbus A350 Long Haul instead of the current one – look out for 2013 Business Class seats on SQ126/125 from 29th March 2026.
• London Heathrow will have one of its daily Boeing 777-300ER flights downgauged to the Airbus A350 Long Haul from July 2026, a likely European debut for the airline’s new Business Class cabin product, as we highlighted back in August last year.
• Melbourne will upgrade to all-long-haul cabins again, with SQ247/248 seeing its Airbus A350 Medium Haul swapped out for the Airbus A350 Long Haul from 29th / 30th March 2026.
• Mumbai will see one of its two daily flights get the usual seasonal downgauge from an Airbus A380 to a Boeing 777-300ER between late July and late August 2026.
• Riyadh is a new route for the airline (or rather, a ‘lost city’ being reinstated) from June 2026, using Airbus A350 Medium Haul aircraft, which will make it the longest flight on the network to use 2018 RJ seats.
• Shanghai sees its daily Airbus A380 flight (SQ830/833) make a return from May 2026, following a brief downgauge to the Boeing 777-300ER during April 2026.

Business Class seats by route and flight number

We’ve updated our seat type list through to the end of the IATA northern summer 2026 season (which runs from 29th March 2026 until 24th October 2026) to help you avoid the guesswork by offering an A-Z destination list, flight number by flight number, seat type by seat type.

To view the flight number list and the corresponding seat type information, click the route of your choice to expand the table, as shown in the example below.

Routes are to and from Singapore (SIN).

Updated: 10th May 2026
Valid until: 24th October 2026

Non-Singapore routes

If you’re flying Business Class with Singapore Airlines on a flight sector not originating or ending in Singapore, here are the seat types used on those services.

Updated: 10th May 2026
Valid until: 24th October 2026

Note that it is not possible to buy or redeem tickets to travel solely on the following Singapore Airlines routes:

• Johannesburg to Cape Town
• Cape Town to Johannesburg

On these flights, you must be travelling to or from Singapore (see earlier tables listed above).

SIA’s “fifth freedom” flights between Hong Kong and San Francisco are currently suspended, while its Taipei – Los Angeles, Manchester – Houston and Rome – Copenhagen fifth-freedom routes have been discontinued in recent years.

Substitutions can occur

The data for this information is based on GDS timetables and programmed seat layouts, and is correct at 10th May 2026.

We keep it regularly updated to ensure it’s a useful long-term reference whenever aircraft types or seat types on a route change.

However, do bear in mind that the list may not be 100% up to date at all times and Singapore Airlines always reserves the right to substitute a different aircraft type at the last minute on any flight due to operational requirements.

This can occur even on the day of operation, so you’re never guaranteed a particular seat type until you step on board.

What about First Class and Suites?

We have an equivalent guide showing where the First Class seat and Suite types are flying around the SIA network, through to October 2026.
