To find your PQDs if >than $12K
Go to
MileagePlus activity since my last statement and it is in the "Account summary" table at the top of the page.

Note this is not just the UA operated PQDs (which is commonly believed to be what matters for GS) but rather your total PQDs.

Definitions

BIS is actual scheduled flight distance (Great Circle Mileage Distance -- GCM) between airports with 500 mile minimum for elites. This is the standard used for Lifetime miles also. Those flying mostly sub-500 segments sometimes prefer to not use the minimum rule.

The definition for CPM is a bit vaguer, especially since CPM is used in multiple different situations.

Believe for the purpose of this thread, GS qualification, folks are using

PQD CPM = UA PQDs / UA BIS

Note there is no direct evidence UA uses this CPM number for GS Qualification but it is a number FTers like to use.

As for BIS, UA does not report this number your account and it needs to be manually tracked.

One way is to make use that PQMs are based on BIS but there may be a multiplier / bonus for high end fares. If always in 2x PQMs, you could divide by 2 to get BIS.

rwsteelers had a good method for determining UA BIS -- the change in Lifetime Miles from the first of the year.
