Just checked on my upcoming TPAC trip where I used PMU upgrades. The receipt showing MXXX under fare class and nothing else. Seats showing WBC seat assignments. Check on the PMUs in my WP account, all 6 still showing "Open" under status. Should I call them back to reissue the tickets? OLCI is not that important to me, but I just want to make sure the upgrade won't get messed up the last minute.

When are the PMUs in the account actually showing being used? after the ticket reissue or after the trip?

thx
