Excellent find Grasshopper! Excellent.
Use EF to check loads as some of the flights in Y in late Aug are already oversold in Y, meaning if you have status on EK, op-ups will be plentiful.
Also remember that there are a lot of Aussies in Europe at present, and at some point, will be returning home, which adds to high loads. The loads at present between SIN-MEL have been sporadic, but my op-up rate over the last 3 flights have been 3 out of 4 (2 from Y to J and one from J to F).
