This is around 10months old this thread, but has the same information / question.
I am planning on attaining QF WP later this year with a large trip. There is a good fare with SIN-MEL in the middle of the journey. This is a QF numbered flight, but is on EK metal.

1. So the question is, do you still attain SC's for this flight and:
2. is it still counted as an eligible sector for the 4QF flight rule?
3. Does it count toward the loyalty bonus too?

This fare is quite a bit cheaper than the QF metal version, so would like to book..but not with reduced earnings!
