I looked it up, and seems the lounge in SFO is the KLM/AF one. Which is weird because I've been in there at a "peak" time (I was on the daily KLM to AMS) and it didn't seem particularly crowded.

Though in general lounge benefits -- unless you're getting a dedicated lounge operated by the program giving you access -- are not something worth going for. Back when I had status on American Airlines, I and many other people learned how worthless the alliance-partner lounge benefits can be: in theory, as an AA Executive Platinum, I'd have access to a rather nice British Airways lounge when connecting to an AA transatlantic flight in Philadelphia, but BA's policy was basically "all times are peak times (so we can turn you away), if there's anyone in here it's at capacity (so we can turn you away), and if there's nobody in here we'll close (so we can turn you away)".

I looked at the Priority Pass offering and did sign up but it didn't seem very useful. I already have United Club (and, by extension, Star Alliance--which I've never had trouble getting access to) and Priority Pass doesn't really buy me anything.
