Having just requalified AA Exec Plat, and will soon get CX Diamond, I thought I'd switch my sights to BA for a change. Though I'm still a lowly BLUE member, I now have 510 tier points.

I've decided to aim for SILVER by August for what its worth by accumulating some domestic AA flights to BA's account.

YYZ-DFW in J : 30 points
DFW-SAN in F : 45 points
AUS-STL in F : 45 points
STL-ORD in F : 45 points

CDG-LHR in C : 30 points
LHR-CPT in C : 100 points?

My question... I will hit SILVER just after the CDG-LHR flight. But I will be laying over in LHR for 12 hours. Would the BA computer calculate the LHR-CPT flight as a 25% bonus flight for having reached SILVER or would it only do so after I get to CPT?
