Singapore Airlines has revealed the next four confirmed routes for its newly inherited Boeing 737-800 fleet, as nine such aircraft progressively move across from regional subsidiary SilkAir into the mainline operation over the coming months.
This new era for the carrier will allow it to gain the flexibility of operating more cost efficient narrow-body jets for the first time in over 30 years, after its small fleet of Boeing 757s was sold to American Trans Air in 1989/90.
In the process the SilkAir brand itself will disappear, as the airline is fully merged into SIA before the end of the 2021/22 financial year.
Where’s next?
Following the initial announcement that these aircraft would serve Phuket from 4th March 2021 and Brunei from 15th March 2021, SIA has now revealed that four additional ex-SilkAir routes will be operated by the Boeing 737-800 in the coming months:
- Phnom Penh (from 17th March 2021)
- Colombo (from 1st May 2021)
- Yangon (from 1st May 2021)
- Mandalay (from 2nd November 2021)
Update 24th February 2021 – Singapore Airlines has added two more routes to the Boeing 737-800’s network from March 2021:
- Chongqing (from 8th March 2021)
- Malé (from 30th March 2021)

Schedules
Phnom Penh is currently being served daily by SilkAir using the same aircraft type. This will be a simple switch across to Singapore Airlines from 17th March 2021, as SQ158/157, retaining daily operation.

The group’s Colombo route is currently a three times weekly Singapore Airlines Airbus A350 Regional operation.

Yangon is also planned from 1st May 2021, provisionally listed as a three times weekly afternoon Boeing 737-800 operation (SQ764/763) on Wednesdays, Thursdays and Sundays, though given the current political situation in Myanmar it’s probably not a definite addition to the passenger network at this stage.
