Here’s our latest update on the Singapore Airlines passenger fleet as of March 2025, covering the ongoing phase-out of ex-SilkAir Boeing 737-800s by October 2025, along with details on around a dozen aircraft slated for disposal, or currently undergoing maintenance.
Unfortunately, the delivery of two new Boeing 737-8 MAX aircraft, initially expected to be in service by now, has been delayed. Despite this, the planned retirement of the Boeing 737-800s remains on track, with another of the ex-SilkAir jets heading to pastures new this month.
SIA’s active passenger fleet now stands at 138 aircraft, still around a dozen short of its pre-COVID fleet, when you consider that SilkAir has now been fully merged into the mainline operation.
Here’s our deep-dive into the latest fleet situation.
Fleet totals
The following table summarises the Singapore Airlines passenger fleet totals as of 28th March 2025.
| CAAS Register (11 Mar ’25): | 150 |
| For disposal or recently scrapped: | -5 |
| In Service: | 145 |
| In maintenance: |
-7 |
| Active: | 138 |
The official registered aircraft data in combination with confirmed retirement announcements and analysis of actual flight movements over the last few weeks allows us to determine the actual ‘in service’ fleet (available to the airline) of 145 planes at 28th March 2025, 138 of which were recently active.

SIA Passenger Fleet at 28th March 2025
The following table shows the Singapore Airlines fleet, including how many of each aircraft type are legally registered (‘Registered’), available to the airline (‘In Service’), and currently operating revenue passenger flights (‘Active’).
| Type |
Registered | In Service | Active |
A350-900 LH |
34 | 34 | 33 |
| A350-900 MH |
24 |
24 | 23 |
| A350-900 ULR |

13 | 12 | 9 |
737-800 |

4 | 4 |
737-8 MAX |
16 | 16 | 16 |
777-300ER |
25 | 22 | 21 |
787-10 |
26 | 26 | 25 |
| Total | 150 | 145 | 138 |
The following aircraft remain registered to the airline but will not be returning to the operating fleet, and are therefore excluded from the ‘In Service’ column:
- 1 Airbus A380
- 1 Boeing 737-800
- 3 Boeing 777-300ERs
This reflects an available fleet of 145 aircraft, plus future deliveries of Boeing 737-8 MAXs, Boeing 787-10s and Boeing 777-9s still on order.
Average fleet age
Singapore Airlines likes to maintain a young fleet, typically retaining its passenger aircraft until they are around 15 years old, a decade earlier than most carriers will plan such retirements.
The current in-service fleet boasts an average age of only 7.6 years as of 28th March 2025. Here’s how it looks by fleet.
| Type |
Average Age |
| A350-900 LH | 6.4 years |
| A350-900 MH | 5.2 years |
| A350-900 ULR | 6.6 years |
| A380-800 | 11.2 years |
| 737-800 | 9.7 years |
| 737-8 MAX | 5.8 years |
| 777-300ER | 14.9 years |
| 787-10 | 4.7 years |
| All Types | 7.6 years |
The oldest passenger aircraft in the fleet is 9V-SWB, a Boeing 777-300ER, which is 18.4 years old.
The Boeing 777-300ER fleet will continue to be the ‘achilles heel’ for the airline in terms of fleet age, as these aircraft are retained much longer than originally intended, due to well-documented Boeing 777-9 delivery delays.
The first of 31 Boeing 777-9s SIA has on order now won’t arrive until 2026 at the earliest, and possibly even in 2027, by which time the 777-300ER fleet will have an average age of nearly 17 years and 9V-SWB will be over 20 years old.
Another Boeing 737-800 has left the fleet
In our recent fleet updates, we’ve shared the good news that Singapore Airlines is making steady progress in returning its seven inherited ex-SilkAir Boeing 737-800s to their leasing companies.
This will eventually see all these aircraft, which feature recliner seats in Business Class, phased out of service on 25th October 2025, as we reported last month.
This month an additional aircraft, 9V-MGE, has joined the list of retirements, leaving passenger service on 21st January 2025, following a flight from Phuket.
The aircraft has since flown to Kuala Lumpur for de-lease preparation, and will be returned to its owner, SDH Wings, in due course.
Unlike 9V-MGC and 9V-MGD, which joined Virgin Australia after their SIA leases ended, 9V-MGE will join Danish charter airline Jettime.

Between April and December 2025, the remaining four aircraft will also bow out of SIA service, as new Boeing 737-8 MAX aircraft are delivered, finally removing those unpopular recliner Business Class seats from the network.
In the meantime, we have a full guide on where you’ll find the Boeing 737-800s flying on the network over their final few months of service.
Fleet activity by registration
Here’s a breakdown of the SIA fleet of passenger aircraft based on recent revenue flight activity, from an analysis conducted on 27th March 2025.
Airbus A350s
33 of SIA’s 34 Airbus A350-900 Long Haul aircraft in the fleet were active as of March 2025, with one aircraft in maintenance.

9V-SKF is still parked at Changi awaiting its fate – sadly it will be broken up and used only for spare parts.

Maintenance woes continue to plague the carrier’s Airbus A380 fleet, with the superjumbo removed from Delhi, Mumbai and London routes in early 2025.
We recently confirmed the type’s deployment on the network for the summer 2025 season, which will see it deployed to only three cities consistently.
Boeing 737-800s
Four of the seven ex-SilkAir Boeing 737-800s that moved across to Singapore Airlines are in regular service, with 9V-MGE now undergoing preparations for return to lessor, following its withdrawal from the operating fleet in January 2025.

A350 refits should start in 2025
Singapore Airlines recently announced that it would be refitting its 34 Airbus A350 Long Haul and seven Airbus A350 ULR aircraft with brand new Business Class cabin products, due to enter service from early 2026, as part of a S$1.1 billion retrofit programme.
The A350 ULR aircraft will also receive the carrier’s new First Class cabin product, though not until the first quarter of 2027.
Refits of the Airbus A350 Long Haul jets should commence in late 2025, to meet the target early 2026 launch.
The first aircraft always takes longer to refit – potentially two to three months, but then the schedule calls for each subsequent refit to take just 1.5 months on average, assuming each A350 goes in for the work one at a time.
Upcoming deliveries
Singapore Airlines was originally due to take delivery of two new Boeing 737-8 MAX aircraft during this financial year (i.e. by 31st March 2025), bringing its MAX fleet to 18, however these have been further deferred due to production delays at Boeing.
It seems likely that they will now take place in the 2025/26 financial year between April 2025 and March 2026, potentially along with some more 737 MAXs and additional Boeing 787-10s.
Here’s how the latest Singapore Airlines outstanding orders for fleet modernisation and replacement looks, including for freighter aircraft.

Delivery of Boeing 777-9s, which the airline desperately needs to replace its ageing Boeing 777-300ERs, has slipped to 2026 at the earliest.
Frankly 2027 looks like a more realistic prospect, a timeline recently mooted by fellow launch customers Emirates and Cathay Pacific.
What about Scoot?
Here’s how Scoot’s outstanding order book looks, as of March 2025.
The low-cost carrier now has five Embraer E190-E2 regional jets in service, with services to 15 regional destinations now in full swing, including Koh Samui, Malacca and Phu Quoc.

It will be interesting to see where Scoot deploys its remaining four E190 jets, all due for delivery by the end of 2025.
Summary
As of March 2025, Singapore Airlines’ fleet consists of 145 passenger aircraft, with 138 currently active, nearly back to its pre-pandemic levels. However, challenges remain – particularly with the ageing Boeing 777-300ER fleet, which is being retained much longer than expected due to ongoing delays with Boeing 777-9 deliveries.
The airline continues to make steady progress in retiring the ex-SilkAir Boeing 737-800s, even as delays in Boeing 737-8 MAX deliveries persist, with the average fleet age now standing at 7.6 years.
Later in 2025 we can hopefully look forward to additional Boeing 737-8 MAX deliveries, while the Airbus A350 Long Haul cabin retrofit program is expected to commence, likely in the fourth quarter of the year.
The final Boeing 737-800s will also exit the fleet by late October, completing SIA’s transition to an all-flat-bed fleet in Business Class, even on narrow-body aircraft.

The longer they wait for newer aircraft, the more profits they make
Due to fly on the A380 in August to tick the SQ first-suite off my list. Thanks for sharing this, as I had thought they were down to low single digits on their active A380s. Feel a lot more comfortable that we won’t have a mad aircraft swap a’la Qatar.
