Question regarding using my asia mile points to upgrade. I've had two separate successful upgrades from PE Flex to Business and one companion award, but this time around I want to know if this will work.

I have two PE Flex tickets purchased for my fiancee and I and this time around I want her to upgrade with her own points and I'll use my own.

In the past I've used my own points to upgrade both of us to business, I just wanted to know if this time around the fiancee can upgrade using her own points.
