I was debating whether or not to post this since the LHR-SYD MR was less than 2 cpm but hopefully someone will like it. 20k miles works out to about 3.8 cpm for mqm.

If you add the 10k bonus miles for LAX-SYD it makes it 2.5 cpm + any elite bonuses.

I only checked September but there were plenty of dates.
