So, I have never been GS before so am curious on how this works. Seems like GS qualification is driven by not just high spend (total $$) but high CPM. And I have learnt from other forums that CPM is effectively pre-tax fare/BIS miles.

A few questions: how do you calculate BIS miles? Is this something United shows on their website under MileagePlus activity? I don't have many miles (relative to others) but I almost always fly Business or First and have only flown United metal this year.

84,110 PQM
$41,456 PQD

I have two more flights to go this year so may end at around $45K PQD for the year.

Any guidance from you experts is greatly appreciated. Thank you
