if the loads are not good on it.. why make it daily.. it used to be full nearly everyday.
In one word: cargo.
It used to be full nearly everyday when it was non-stop to SIN meaning Oz became a one stop destination as it is with EK, QR and EY now.
To be fair to SQ, it amazes me how much effort they have put into MAN and are still trying! They must have some faithful MAN passengers!
