I'll be traveling to China in a few days and there seems to be a lot of empty seats in business class.

In the past I've taken a chance, almost always unsuccessful of getting a free upgrade.

My question is: If I am offered this upgrade when checking in for $$, will the amount I pay be credited for PQD?

I'm asking since I will be close to qualifying for 100k for the first time. Thanks!
