Your status is the primary driver, even for the BXP3. You will be behind CK and EXP and ahead of PPros on complimentary upgrades. for other PPros using BXP/SWU/miles+copay, you will be prioritized by rolling LP count.
One more quick question, does being booked in Premium Economy W give me any priority over others in Coach to get the upgrade with BXP3?
