Singapore Airlines announced this morning that their newest aircraft type, the Airbus A350-900 in regional configuration, will join the fleet in December this year starting with flights between Singapore and Adelaide.
Seat layout
The aircraft will be fitted with 40 of the latest 2018 Regional Business Class seats in a 1-2-1 configuration, a product we reviewed in April on the Boeing 787-10. That’s 4 more seats in Business Class on this plane compared with the 787-10.
The A350 has a slightly wider fuselage than the 787, so we expect a little more aisle room on this plane as the seats themselves should be identical.
As expected there is to be no Premium Economy cabin on this particular variant, with 263 Economy Class seats in a 3-3-3 configuration making up the balance of the floor space on this new jet.

In Business Class there will be 10 rows in total with a 1-2-1 configuration. The first 7 rows will be positioned in the forward cabin section between the first and second main aircraft doors, with 28 seats.
Behind the second door a small 3-row cabin will feature, with 12 seats in total.

That’s not particularly helpful – due to the staggered seating arrangement travellers need to know which seats have the console located between the seat and the aisle, and vice-versa. This also helps to choose (or avoid) the middle seat pairs directly alongside one another, which are ideal for couples but less so for solo travellers.
Singapore Airlines has not published a detailed set map yet so we have taken the liberty of creating our own which shows the planned layout.

Be careful to note that row 18 and row 19 have the same arrangement (due to the cabin door separating these two sections). It’s therefore not as simple as the alternating row arrangement found on the 787-10.
Some other things we know so far about the Business Class cabin:
- Row 11 is reserved for advance selection to PPS Club members only on longer flights with this aircraft. It is blocked to other passengers on such flights until online check in opens 48 hours prior to departure. This is not the case on the 787-10 regardless of sector length, so we suspect it’s a hangover from the aircraft type rules (359) in the reservation system, which will probably be ironed out later.
- Seats 19A and 19K are the bassinet positions.
- Unlike the current Singapore Airlines A350s, we expect overhead lockers to be installed in the centre cabin ceiling section in Business Class.
- Four bassinet positions in the Economy Class cabin are directly behind row 21, the last row in Business Class. It may be preferable to secure a seat in the forward section.
- If you are trying to determine whether your A350 flight has the 2018 RJ seats or the 2013 J seats from the seat map, seats 18A and 18K only exist on the A350 regional aircraft with 2018 RJ seats, they are not present on the standard A350 and the A350ULR does not have a row 18 at all.
- If you prefer to check the last seat row number in Business Class – it’s Row 22 on the standard A350 (2013 J seats), Row 29 on the A350ULR (also 2013 J) and Row 21 on the A350 regional (2018 RJ seats).

In Economy Class the A350 regional has two large cabin sections, the first starting behind the Business Class cabin and running to the third main aircraft doors, and the rear section between the third and fourth aircraft doors.

Takeaway points for the Economy Class cabin:
- The ‘forward zone’ spans from row 41 to 47, highlighted in green on the seat map.
- Six extra legroom seats (highlighted in orange) are located at rows 55 and 56.
- Couple pairs are at 55B/C and 55H/J (also extra legroom) and at 69B/C and 70B/C.
- Bassinet positions are primarily at row 41, directly behind the Business Class cabin, with an additional position at 55G.
Wi-Fi
The A350 regional aircraft will be equipped with Inmarsat GX Wi-Fi capability, provided through SITAONAIR, in common with the new A380 Version 3 aircraft but interestingly a switch from the existing A350s / 787-10s which use the Panasonic system.
We therefore expect the pricing plans to be similar to those offered on the new A380 and we’ll try to confirm this closer to the launch.

The schedule
The A350 regional will debut on the Singapore – Adelaide route from 17th December 2018 as SQ279/278, replacing an A330 on that flight pairing.
From 17th December 2018 (18th December 2018 from ADL)
Flight | From / To | Aircraft | Days |
SQ279 | SIN2335 – ADL0905* | 359 | Daily |
SQ278 | ADL1025 – SIN1510 | 359 | Daily |
* next day
This new aircraft will also bring a total 6.3% capacity increase to the Adelaide route, with 10 more Business Class seats than the current A330 offers (33% more) and 8 more seats in Economy Class (3% more).

If you’re looking to try this new product on the A350 Regional or 787-10 we have updated our 2018 RJ tracker page with the all the latest route information including the Adelaide service.
Redemptions
As this is aircraft has a regional Business Class product, you can use miles from other Star Alliance programs to book Business Class redemptions, such as Lifemiles and United Mileage Plan.
If you have an eligible ticket in Economy Class on this aircraft, you can use KrisFlyer miles to upgrade to Business Class, since there’s no Premium Economy cabin getting in your way.
We checked award availability on the Singapore – Adelaide route for the first few weeks of service following the introduction of the A350 regional and found 2 or more saver award tickets available for booking on around half the dates searched, which isn’t bad.
Northbound between Adelaide and Singapore availability is more scarce, however this is likely due to the Christmas and peak school holiday season in Australia and we think the additional 10 seats in Business Class compared with the A330 should help with longer term redemption availability on this route.
Summary
It’s good news that more aircraft are joining the fleet with the new regional business class cabin this year, with two more 787-10s to arrive in October and this first A350 regional jet, not originally expected until 2019, starting flights in December.

From a strategic perspective SIA has gone with a larger Business Class cabin in the A350 regional than on the 787-10, while a smaller Economy Class cabin was probably inevitable due to the shorter length of the A350-900.
That could lead the airline to target more business-heavy regional routes with the A350 regional, while concentrating the 787-10 aircraft on routes needing higher total capacity.

This is a very succinct analysis showing various strategies in snagging a good seat (for those with miles and $$), and for aircraft deployment from the airline’s point of view, without too many confusing screen grabs. Thumbs up
Did the seat map you provided in your write-up came from SQ? If so, it is annoying because the seat map does not indicate the actual layout for J i.e. the locations of each seat console (to the right or left), so that we will know which middle J seats are couple or divorce seats. I checked the website but could not find an updated fleet information relating to A350 medium range aircraft only the current A359 and A359 ULR.
Hi Chris the seat map featured is from the booking engine, as you mentioned SIA has not yet published the seat map showing which window A/K seats are aisle-exposed and which middles are in pairs and separated.
However it is like this on the A350 Regional:
A/K seats at 12, 15, 17 & 20 have the console between the seat and the aisle (seat is closer to the window)
A/K seats at 11, 14, 16, 18, 19 & 21 have the console between the seat and the window (seat is closer to the aisle)
D/F pairs at 11, 14, 16, 18, 19 & 21 are the couple pairs directly alongside one another (with the console between the seat and the aisle). D/F pairs at the other rows have the console between the seats (seat is closer to the aisle).
Remember row 18 and 19 are separated by a cabin door, so the alternating sequence is interrupted and both row 18 and row 19 have the same configuration before it starts to alternate again.
Hope it makes sense, will try to get a detailed seat map up later.
Detailed seat map now uploaded to the article. Hope it helps.
Thank you very much, Andrew!!
Hi
Thanks for the updates…I have a question you may or may not be able to answer for me. We are travelling on an Adelaide to Singapore flight in March of next year. I was wondering if you can tell me if Seat 42 J and K, of which were chosen for us…we had a window seat with a view before the plane change…are good for a view? Now i was being inquisitive to ask, do you think the view from here will be ok for my virgin flight to Singapore? I mean I want it to be memorable and watch the world go by as we land…silly I know but it’s something I’m looking forward to!
If not what would your opinion be on better seat choice, in good old economy!
Many thanks,
Jodie
Thanks for the detailed write up and seat analysis. As an ADL based traveller, I am relieved that SQ is finally pulling the A330 slopers from this route. It’s been a long time coming!
