Singapore Airlines announces May 2021 schedule

Singapore Airlines takes on four routes from SilkAir in the coming months, and tweaks some frequencies on its network, as it maintains 25% passenger capacity.

Singapore Airlines and SilkAir have announced their flight schedules through to the end of May 2021, adding an additional month to the previously confirmed route list, which was had been published through to 30th April 2021.

Besides some route transfers from SilkAir to the mainline carrier, including Phuket and Malé, there are no new routes planned, meaning a total of 42 cities linked by SIA and four by SilkAir through to the end of the new schedule period.


The passenger network over the next three months is set to be served by the following aircraft types:

  • Airbus A350-900s
  • Boeing 737-800s
  • Boeing 777-300ERs
  • Boeing 787-10s

Overall the SIA Group will operate 25% of its pre-COVID passenger capacity by May 2021, its largest schedule since the COVID-19 pandemic hit.

Sydney is set to become the airline’s busiest passenger route with 17 weekly flights from April 2021, followed by Jakarta and London with 14 flights per week.

In total SIA and SilkAir will fly over 2,200 passenger flights during May 2021, in common with April 2021 as the highest total since the pandemic hit.

“The Group’s passenger capacity will reach approximately 25% of its pre-Covid-19 levels by the end of May 2021.”

Singapore Airlines Schedule

The most significant change for Singapore Airlines in the coming months is the addition of four new routes as a consequence of the SilkAir – SIA merger, which is now entering its final stages and involves the transfer of nine Boeing 737-800s into the mainline operation.

This will mark a new era for the carrier as it introduces narrow-body aircraft service for the first time in over 30 years, with the following routes in the initial tranche to move across:

  • Chongqing
  • Malé
  • Phnom Penh
  • Phuket

As the SilkAir – SIA merger progresses, don’t miss our full rundown of what to expect on board the narrow-body Boeing 737 aircraft from March 2021.


This month sees the first former SilkAir Boeing 737-800s joining the Singapore Airlines fleet, meaning routes like Phuket and Chongqing moving across to mainline operation.

Aside from some minor frequency changes to and from other cities, the airline is maintaining more or less the same schedule across the period, with 25% of pre-COVID passenger capacity offered, though actual passenger numbers remain extremely low at around 3% of usual levels, based on January 2021 data.


With COVID-19 border restrictions remaining in force there is some light at the end of the tunnel as vaccinations roll out and countries like Australia and Thailand begin pointing towards relaxations for vaccinated travellers later in 2021.

Realistically though there is likely to be little discretionary travel opportunity until the second half of this year, so any significant further SIA schedule expansion between now and then seems unlikely.
