However this maneuver could be just too complicated and also bears a bit of risk.
I have been buying PEY (and Y before there is PEY) for my wife and get her upgraded to J. I never did upfare. I have been successful every time except once. The risk of upfare is high. We may be forced to buy W instead of R, and W fare is close to 2X R fare for SFO-HKG.
