Malaysia Airlines Airbus A350s for Sydney running to end of April 2019

Malaysia Airlines will keep flying its Airbus A350 on KUL-SYD as MH122 / MH123 until April 30, instead of going back to an A330 at the end of the summer peak season. This now includes 'Business Suites' instead of 'First Class', this is been written up pretty comprehensively at https://www.ausbt.com.au/malaysia-airlines-drops-first-class-rebrands-it-as-business-suites. Of course being MH you can't rely on this being an A350 every day, it really hit very much hit-and-miss and can be back to an A330 without warning!

I see A350 on their MH140 (overnight) out of Sydney to KL recently and the daytime MH141 to Sydney from KL - though seems to be A330 every other day - not sure what that means
