I'm about to do a mammoth trip CGK->KUL->LHR->JFK->LHR->HKG->CGK in Club World, and 4 of the sectors are on BA, the remaining 2 on partners (CX & MH). I'm theoretically destined to receive 760 tier points (none on MH) so my question is this... to qualify for Silver are the 4 sectors and 760 tier points enough in one itinerary or is it the case that I will actually need to qualify for Bronze first (ie 300 + additional sectors).

Apologies if this has been covered elsewhere.
