Can we assume that you have. KLM ticket for a KLM operated and marketed nonstop from AMS to SFO?
I'd be pessimistic, although it could depend somewhat on what day of the week you're traveling, which I am deliberately not bothering to check myself. Also, how can July 12th be "six days from takeoff"?
AFAIK you cannot be upgraded on board, nor would there be a mechanism to pay with miles for the upgrade on board.
