Flights are often full, so there's no guarantee of availability at the airport. It might be cheaper to do a HKG - BKK mr.
Because I wasn't clear where the OP was originating from, I simply calculated a RT using the NA East to Far East table (flex). My humble apologies if I was wrong.
I also should have been clearer in the fact that additional tier miles are unlikely via pre-departure upgrades (unless they completely re-issue the ticket to a J class and you pay the difference). I meant to say that the OP could do this well before. I have altered my saver fare to a flex fare (Y) before so the upgrade to J didnt cost me as many miles, but I did this well in advance of the travel date.
