SIA Fleet: Airbus A350-900 Medium Haul

The Singapore Airlines Airbus A350 fleet operates in three configurations. This page details the A350-900 Medium Haul configuration, sometimes referred to as the ‘A350 Regional’.

This variant operates short- and medium-haul flights from Singapore across the Asia-Pacific region. The first aircraft was delivered in November 2018, and entered service on 17th December 2018.

How can I tell which Version I’m flying on?

If you’re flying in Business Class and the seat map ends at row 22, you’re in an A350-900 LH aircraft, if it ends at row 21 you’re in an A350-900 MH aircraft (you’re on the right page already), and if it ends at row 29 you’re in an A350-900 ULR aircraft.

If you’re flying Premium Economy Class and the seat map goes up to row 33, you’re in an A350-900 LH aircraft. If it goes up to row 43, you’re in an A350-900 ULR. The A350-900 Regional does not feature a Premium Economy cabin.

If you’re flying Economy Class and the seat map goes up to row 62, you’re in an A350-900 LH aircraft. If it goes up to row 70, you’re in an A350-900 Regional (you’re on the right page already)The A350-900ULR does not feature an Economy cabin.

The A350-900 Medium Haul started flying in the Singapore Airlines fleet on 17th December 2018 between Singapore and Adelaide, then the following day between Singapore and Jakarta. Flights to Brisbane and Kuala Lumpur followed shortly afterwards, with the aircraft now in extensive use, having effectively replaced the carrier’s Airbus A330s, which left the fleet prematurely in early 2020 due to the COVID-19 pandemic.

The aircraft is fitted with the latest 2018 Regional Business Class seats, which also feature on SIA’s Boeing 787-10 aircraft. We have a full review of the product available here.

A350-900 Regional Business Class

Singapore Airlines’ 2018 Regional Business Class seats on the A350 MH aircraft are arranged in a ‘staggered 1-2-1’ layout, as they are on the Boeing 787-10 aircraft. Though the seats are identical, the aisles on the A350 are slightly wider by about 6cm each compared to the 787, due to the wider fuselage.

Unlike the 787-10, the Business cabin on the A350 MH is split across two sections, a larger forward section and a 3-row mini-cabin behind the second main aircraft doors.

Of the 40 Business Class seats on this aircraft there are 6 couple middle pair opportunities at 11D/F, 14D/F, 16D/F, 18D/F, 19D/F and 21D/F. Since row 11 and row 19 are at the bulkhead position, that means two of these pairs feature additional space, easier access and slightly longer bed length. See our special review of the middle pairs at row 11 on the 787-10 for details.

If you’re a fan of privacy there are 8 of the individual window seats with the storage console located between the seat and the aisle at 12A/K, 15A/K, 17A/K and 20A/K.

Best Seats

Seats 11A and 11K, the window seats in the front row, each feature a bassinet position which unusually also doubles as a very handy storage area if you’re travelling without an infant.

Seat 3
The bulkhead window seats in the 2018 Regional Business Class cabin, pictured here on a 787-10, feature a bassinet position which doubles as additional stowage in-flight. (Photo: MainlyMiles)

While stowage there is not permitted for takeoff and landing, once in flight it’s a very useful place to have your bag in easy reach throughout the journey.

The foot well and stowage directly beneath are also much bigger at all row 11 and row 19 seats, making the seat slightly bigger when converted to bed mode too. The literature pocket is also a more useful flat shape for stowing your own items. See our mini-review for details.

Be aware however a Business Class toilet is located directly ahead of seat 11A and the Business Class galley is located in front of row 11, meaning more noise and foot traffic in this area. If an infant is travelling in one of the bassinet positions (seats 19A or 19K) there is also the possibility of some disturbance near those seats.

Row 11 is blocked for advance seat selection until 96 hours prior to flight departure time on all A350 MH aircraft, unless you are a PPS Club member. Row 19 is unaffected.

Worst Seats

Row 18 is directly in front of the other two Business Class toilets, and row 19, the first row in the smaller rear section, which has two bassinet positions. There are also 4 bassinet positions at the first row of Economy Class, directly behind row 21, with only a partition divider here.

We would aim towards the mid section of the forward cabin on a longer night flight for these reasons.

A350-900 Regional Premium Economy Class

There is no Premium Economy Class cabin fitted on the A350-900 Regional, only Business Class and Economy Class are featured.

If you are flying in Premium Economy Class on a Singapore Airlines A350 you must be flying on the A350-900 LH or A350-900 ULR, not this ‘Regional’ MH variant.


A350-900 Regional Economy Class

Economy Class is in a 3-3-3 configuration on the A350 Regional aircraft. This is fitted with the same 2017 generation Economy seats as those featured on the 787-10.

Again the aisle width is slightly better due to the wider fuselage of the A350.

Forward Zone seating, which attracts an additional charge for those travelling on Economy Lite and Economy Standard fares (unless they hold KrisFlyer Elite Gold or PPS status) is located at rows 41 to 47.

Best Seats

Extra legroom seats are at 55B/C/H/J and 56A/K positions.

Two elusive pairs are available at 69B/C and 70B/C, ideal for friends or couples travelling together

Worst Seats

In terms of bassinets, 4 of the 5 available in this cabin are located at row 41 (directly behind the last row of Business Class – why do airlines do this?), with the remaining single bassinet at seat 55G. There could be some additional disturbance near these seats on flights with an infant travelling.

A large bank of four toilets (the middle toilet depicted is actually two) is located behind row 54, and all passengers in the forward Economy Class cabin section will be walking back to this area to use these, resulting in increased foot traffic and noise around this area.

    1. This page is updated monthly and currently shows aircraft in service at 6th May 2019. SHF will be added in the June 2019 update.

  1. Thanks Andrew for this wonderful site!

    Just to share – I referred to this and booked 11K for the extra storage (bassinet position) on the A350 Regional (9V-SHG), but was surprised to find that the configuration was different from the 787-10 – that is the Row 11 window seats had no extra storage at all. Only seats 19 A & K had those. Not sure if it was a special configuration?

  2. Great article! I have a question how to reserve a PE seat when PE is not officially sold. E.g., SIN-CGK SQ 962 on A350-900. The A 350 has PE but PE is not offered for redemption (and I also don’t think for revenue tickets). Currently the PE seats are not selectable (not even with a fee). Will the PE seats become selectable when online check in opens? Will there be a fee? Any other tricks to get them? Would be fantastic to only pay 7.5K miles for PE. Thanks

    1. PE seats on these routes are usually only available to Elite status holders, and even then they are only released once the flight reaches a certain load factor in Economy Class.

      The service is no different it is just considered Economy Class so you’re not missing out on much!

      1. Thanks Andrew! So even during online check in these seats won’t open up for non-elites? I am mostly interested in the seat comfort which is still above regular economy, don’t need much service on a 90 minute flight.
