Hi Jesper...
20,000 miles to upgrade seems kind of "expensive".
I think an upgrade to Royal Silk from LAX/BKK is 40,000 miles...(18 hr flight)?
For just another 1000 baht, it's worth the expense. But, I always spend the extra 1000 baht for BKK/HKT, and save the mileage points for longer range upgrades.
Enjoy your stay. (Are you at the SH hotel, as usual? Say Hi to all for me.)
Pablo
