Try shopping EWR SFO in February 2011, Advanced Search, and check OnePass Reward Upgrade.
My habit had been to request the upgrade to SFO shortly after booking, just to get on the list. I was surprised to clear immediately, recently. Searches revealed scattered availability, more than I've seen before, with no regular pattern. One could improve ones odds by shopping with this checkbox on, a step that never seemed worth the bother before.
