Mileage Calculator got the double SC offer

[medhead]

I did a check of discount economy SYD-AKL and that seems to be correct at 20SC. Are international routes unaffected?

It might have been lost in the static. But I've checked and the milage for SYD-AKL is ~1300. The calculator is showing the correct SC earn for this route - 20SC. So why is this route correct and domestic routes aren't. Are other international routes correct? Is this a sign of an enhancement for domestic?

SYD-SIN, ADL-SIN are correct.
