I was considering a purchase using AMEX points and applying SWUs to the flights. Does this work? I’ve got a pair of the cheap business class tix on hold HKG to MEX via Dallas and was thinking of using to upgrade to first. My wife’s not going to take a chance to be stuck in Econ if don’t clear and I probably can use the EQDS AND EQMs.

addl question on the HKG route to DFW. I see all but one seat available in first for a mid Oct flight. This can’t be true do they block all but one or two initially?
