I bet the JFK/HKG/BKK route is pretty popular for upgrades, and you are probably travelling at a peak period. So yes, the earlier you do it the better. If you call in, you can ask to be put on a waitlist if there are no immediately available redemptions. But remember elite MPC members get priority, so if you aren't, then chances are probably low.
