I may be wrong, but I believe upgrades are processed within:
Platinum 72 hours
Gold 48 hours
Silver 24 hours </font>
Where did you get that? I have been upgraded as early as Sunday for a Satrurday flight. According to Northwest, Platinum, 5 days priot, Gold, 3 days prior and Silver 1 day priot to the date of travel.
