I would suggest crediting them to Alaska. I travel to Thailand frequently and when I first started in this game I didn't know any better and now I have about 50K miles in Korean which are almost worthless to me as I want to redeem them for travel from US - SE ASIA, and the fees on Korean don't make it worth it. Only thing I have found are useful for KE miles are for intra-asia travel, in some cases that can be worth it. But without knowing specifically your flying patterns and desired outcomes I would suggest Alaska
