Rate as of today from BKK-CDG is exactly 26,000 Baht to upgrade from Y to C and 825 USD equivalent from CDG-BKK (using 1.41 conversion, comes to ~581 Euros). The agent reconfirmed me that I would earn Biz class miles, and not Eco. Using 1.41 makes sense for EUR-USD but converting 825 USD to 26K Baht seems to use a strange exchange rate.
After I hanged up, then I am now thinking about how this mileage credit would work when upgrading Award tickets as mentioned by TK.
