SIA’s active fleet stands at 139 passenger aircraft this month, as two new Boeing 737-8 MAX jets arrive, following a 2.5-year hiatus for narrow-body fleet expansion.
Here’s our latest update on the Singapore Airlines passenger fleet as of June 2025, covering the recent delivery of two new Boeing 737 MAX aircraft following a 2.5-year hiatus, the ongoing phase-out of ex-SilkAir Boeing 737-800s by October 2025, and details of aircraft currently flying or undergoing maintenance.
There’s also visibility on some upcoming wide-body aircraft deliveries over the next nine months.
SIA’s active passenger fleet now stands at 139 aircraft, two more than our last update, but still around 10 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 30th June 2025.
| CAAS Register (9 Jun ’25): | 149 |
| For disposal or recently scrapped: Recently delivered: |
-5 +2 |
| In Service: | 146 |
| In maintenance: Yet to enter service: |
-5 -2 |
| Active: | 139 |
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 146 planes at 30th June 2025, 139 of which were recently active.

SIA Passenger Fleet at 30th June 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’).
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 146 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 7.8 years as of 30th June 2025. Here’s how it looks by fleet.
| Type |
Average Age |
| A350-900 LH | 6.7 years |
| A350-900 MH | 5.4 years |
| A350-900 ULR | 6.9 years |
| A380-800 | 11.4 years |
| 737-800 | 9.8 years |
| 737-8 MAX | 5.4 years |
| 777-300ER | 15.2 years |
| 787-10 | 4.9 years |
| All Types | 7.8 years |
The oldest passenger aircraft in the fleet is 9V-SWB, a Boeing 777-300ER, which is 18.7 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.
Two new MAX aircraft have been delivered
Since our last fleet update, Singapore Airlines has taken delivery of two new Boeing 737-8 MAX aircraft, though both are yet to enter passenger service with the latest one still winging its way to Changi at the time of writing.
These aircraft were originally due to be delivered in the last financial year (i.e. by 31st March 2025), but were deferred due to production delays at Boeing.

Recent deliveries
| Reg. | Delivery | Service Entry |
| 9V-MBQ | 10 Jun 2025 |
Yet to enter service |
| 9V-MBR | 28 Jun 2025 |
Yet to enter service |
This represents the first delivery of MAX jets to the carrier since November 2022, some 2.5 years ago, bringing the fleet to 18 of the type.
As we recently reported, the Boeing 737-8 MAX fleet will see the bulk of new deliveries at the airline over the next year or so, with this pair the first of six due to be added to the fleet by the end of March 2026, which will take the narrow-body fleet to 22 MAX aircraft in total.
This will achieve complete replacement of the carrier’s Boeing 737-800s, and some fleet expansion too, leaving a further seven MAXs still due to arrive from April 2026 onwards, for a final fleet of 29.

An interesting point to note is that these latest aircraft have both taken what we believe to be a new shorter delivery routing to Singapore – from Seattle to Fairbanks, Alaska and then on to Tokyo Narita before making the final leg of the journey to Changi.
Previous Boeing 737-8 MAX deliveries to the airline have routed via Honolulu and Guam instead, around 1,000 miles longer.
Another Boeing 737-800 has left the fleet
Over recent fleet updates, we’ve been sharing the welcome news that Singapore Airlines is making steady progress in returning its seven inherited ex-SilkAir Boeing 737-800s back 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 earlier this year.
Recently an additional aircraft, 9V-MGK, has joined the list of retirements, leaving passenger service on 7th May 2025, following a flight from Kuala Lumpur.
The aircraft has since flown to Kuala Lumpur for de-lease preparation, and will be returned to its owner, London-based Deucalion Aviation, in due course. The aircraft’s next operator has not yet been disclosed.
Meanwhile 9V-MGE, the previous Boeing 737-800 to leave the fleet, was formally deregistered in late May 2025 and has joined Danish charter airline Jettime as OY-JYD.

Between now and late October 2025, the remaining three aircraft in this fleet 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 29th June 2025.

9V-SKR returned from Teruel, Spain, in March this year, where some maintenance work was conducted, but still hasn’t re-entered service, suggesting further work is being carried out here in Singapore.
9V-SKF is still parked at Changi awaiting its fate – sadly it will be broken up and used only for spare parts.

Three aircraft are stored at Changi, and will not be entering service again 9V-SWD, -SWF and -SWN.
Additionally, one aircraft is in maintenance at Changi, – 9V-SWT.

This is an unusually long down-time for an 8-year old aircraft, and we assume this is cannot be the intended use of such an expensive asset.
A350 refits should start this year
In late 2024, Singapore Airlines 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
Aside from four new Boeing 737-8 MAX deliveries and three Boeing 737-800 removals, there will be new wide-body aircraft joining the Singapore Airlines fleet over the next nine months.
These will come in the form of two Boeing 787-10 aircraft for regional operations, bringing the 787 fleet to a total of 28, with only three more deliveries then due after that, before the carrier’s full order of 31 such aircraft is in service.
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 June 2025.
The low-cost carrier now has six Embraer E190-E2 regional jets in service, with 9V-THG the latest to join the fold since 19th June 2025.
The type currently operates services to 15 regional destinations, including Koh Samui, Malacca and Phu Quoc.
It will be interesting to see where Scoot deploys its remaining E190 jets, all due for delivery by the end of 2025.
As of June 2025, Singapore Airlines’ fleet consists of 146 passenger aircraft, with 139 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 good news for this update is that narrow-body aircraft deliveries have finally restarted, after more production troubles at beleaguered Boeing are finally ironed out, with two new 737-8 MAXs joining the fleet in recent days.
This will help SIA make steady progress in retiring its ex-SilkAir Boeing 737-800s, with four further new MAXs in line for delivery over the next nine months. The final Boeing 737-800s will exit the fleet by late October, completing SIA’s transition to an all-flat-bed fleet in Business Class, even on narrow-body aircraft.
Later in 2025 or in early 2026 we can look forward to two additional Boeing 787-10 deliveries, while the Airbus A350 Long Haul cabin retrofit program is expected to commence in just a few months from now.
