1) Approximately how much would I have to spend on flights (100% PQM) as an Economy/Premium Economy buyer to hit a Silver/Gold Status (3000/6000/etc PQD)? I'm currently 12,500/25000 and $900/$3000 for PQM/PQD and I'd love to reach at least Silver by next year as a test for my road-map for the future

2) How does one exactly calculate how much PQD you get from a flight? I know it doesn't include fees or tax, but it still feels way lower than what you pay for the actual flight fare.

Thanks!
