QF9/10 Not Operating Tuesdays in November

[hotpaws]

Hi all,
I have just noticed that QF9/10, the MEL-LHR A380 service, is not operating on Tuesdays throughout November.
This, in itself, is not unusual, the same thing happened at this time last year. What I do find strange, however, is that for both services the cancelled flight is on Tuesday. This would mean that the aircraft would be on the ground at Heathrow, and not Sydney. I guess the additional cost of keeping the aircraft on the ground in LHR is offset by the difference in loads on Tuesday vs Wednesday for QF10?
Anyone have other thoughts on this?

Also the second SYD- HKG is also not operating on some days during Nov. Not sure if its low loads or maintenance.

Well there is a public holiday on the first Tuesday in November. That could be part of the reason why Tuesday was chosen, I guess.
