I assume it will be the one-way rate, but I wanted to confirm.
One way rate is charged if you only fly one way....allowing you to "book" a round trip (no doubt always choosing a fully booked return flight) and only paying half for one way would be the biggest loophole running since offshore banking was invented.
If the return sector ultimately clears, you will be charged for 2 one ways....but you can claim back the difference. Asia Miles will refund you the amount of miles between the round trip and two one ways. So you don't get screwed if they clear at different times.
