Singapore Airlines Fleet: August 2021

Singapore Airlines has sold seven inherited Boeing 737-800s to Virgin Australia, and picked up a few military charter flights this month.

This month we learned that Singapore Airlines has managed to sell seven of its surplus Boeing 737-800 aircraft fairly quickly, with the jets now set to enjoy a new lease of life with Virgin Australia. The aircraft had been inherited by the mainline carrier following a merger with SilkAir earlier this year.


In other news some of the Airbus A350s have been enjoying some extra work for the military, with trips to Idaho, USA and Paya Lebar Air Force Base this month, in addition to their usual duties.

The penultimate Airbus A330 also looks set to make an imminent final departure.

Fleet totals

Here are the Singapore Airlines passenger fleet totals at 31st August 2021.

  CAAS Database: 154  
  Awaiting certification:
For disposal:
  In Service: 115  
  In maintenance / stored:
  Active: 91  

The official registered aircraft data in combination with recent 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 115 planes at 31st August 2021, 91 of which were recently active.

This 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 or cargo flights (‘Active’).

All the airline’s remaining Airbus A330s, Boeing 777-200s, Boeing 777-200ERs and Boeing 777-300s will not be returning to the fleet after COVID-19, in addition to seven older Airbus A380s, four Boeing 777-300ERs and seven Boeing 737-800s.

These are therefore excluded from the ‘In Service’ column.

Additionally, all currently registered Boeing 737-8 MAX aircraft, which are awaiting re-certification, are excluded from the ‘In Service’ column for the time being.

This reflects a future fleet of 115 aircraft, plus future near-term deliveries of Airbus A350s, Boeing 737-8 MAXs and Boeing 787-10s.



Fleet activity

Four aircraft types are currently in service with the airline, as shown in the table below outlining the number in use at each of our monthly fleet update ‘snapshots’, from April 2020 to date.

Here’s a graphical look at the active vs. stored fleet.

Here’s a look at how busy each aircraft fleet has been, based on active aircraft over the seven-day period from 21st August 2021 to 27th August 2021.

Type Total flights per week Average per active aircraft
Flights per week Daily utilisation
A350 240 9 12.8h
A350 R 303 14 10.5h
A350 ULR 30 4 9.7h
737-800 92 10 3.1h
777-300ER 100 9 7.7h
787-10 214 15 11.5h

Average fleet utilisation is similar by aircraft type compared to our recent updates. Long-Haul Airbus A350s continue to be the ‘workhorses’ in terms of daily flying hours per aircraft, though the other A350s and Boeing 787s aren’t far off.

With fewer Boeing 777-300ERs in active service this month but the same flying network for the aircraft type, utilisation has increased towards 8 hours per aircraft per day.

August 2021 fleet movements

Here’s a summary of the notable movements we’ve seen in the fleet this month:

  • Airbus A350 ULR 9V-SGG operated an interesting charter for the Singapore Air Force on 25th and 26th August 2021, routing from Singapore to Sydney, then Sydney to Paya Lebar Airport, then back home to Changi.
  • Airbus A350 9V-SMW operated from Singapore non-stop to Boise, Idaho, USA then returned via San Francisco on 18th August 2021 before flying the same routing again on 28th August 2021. These are likely to be military charters.
  • Airbus A330 9V-SSH made a test flight in all-white livery on 12th August 2021, suggesting it is being prepared for imminent return to its lessor.
Amazingly, it takes 19 minutes to fly from Paya Lebar to Changi in an A350!
(9V-SGG on 26th August)

Ex-SilkAir 737-800s sold to Virgin Australia

Earlier this month Virgin Australia announced that it had secured an additional nine Boeing 737-800s to meet its expansion goals.

Two of those aircraft are former Virgin Australia jets, while the remaining seven have been acquired from Singapore Airlines and are ex SilkAir aircraft that had been marketed for sale earlier this year.

  • 9V-MGF (age 7.0 years)
  • 9V-MGG (age 6.9 years)
  • 9V-MGH (age 6.9 years)
  • 9V-MGI (age 6.6 years)
  • 9V-MGJ (age 6.4 years)
  • 9V-MGP (age 5.3 years)
  • 9V-MGQ (age 4.9 years)

These aircraft are all currently registered to Singapore Airlines, except 9V-MGJ, which is still registered to SilkAir.

9V-MGI operated the final SilkAir passenger flight from Kathmandu to Singapore on 6th May 2021.

The acquisition of these relatively young aircraft will help Virgin Australia reduce its average fleet age, which currently stands at from 10 years.


The aircraft will be refitted with Virgin’s cabin product.

“These extra aircraft are an important part of our planning and ensure we’re ready to ramp up flying and meet the pent-up demand for domestic travel as soon as the opportunity presents itself.”

Jayne Hrdlicka, CEO, Virgin Australia

The sale of these seven aircraft will leave Singapore Airlines with only one Boeing 737-800 to dispose of, 9V-MGO.

Airbus A330s

There are still just two Airbus A330s in the registered fleet, 9V-SSH and 9V-SSI, due for return to their lessors in approximately Aug/Sep and Sep/Oct respectively, at the end of their six-year lease periods.

!A330v3 Label
Aircraft Location Last flew Days ago
9V-SSH SIN 28 Mar 20 521
9V-SSI SIN 25 Nov 19 645

‘Last flew’ dates relate to the aircraft’s last revenue passenger or cargo-only flight.

9V-SSH took a test flight on 12th August in all-white livery and should be heading off to another home soon, leaving only 9V-SSI to complete the process.
