Anyone know when (or how for that matter) DL updates its systems to recognize NW Elite Status. I was just matched into NW Platinum (based on AA Exec Plat) and I am also DL GM. So in order to take advantage of recipricol status for upgrades I want to change my FF# on my existing itineraries to the NW Platinum.

Does this happen on Saturdays, as the normal DL status updates do?
