Hi Chester,

Your wife can enter the local Plaza Premium Lounges with the Supplementary MBB VI which provides 5 free entries per calender year.

The Priority Pass card is issued only to the principal cardholder and this is also good for another 5 free entries to all lounges under the PP program, i.e. international plus local lounges. Though the PP card can be used locally, you should use up the MBB VI card entitlement first and reserve the PP for lounges in overseas airports since the MBB VI can't be used there.
