So I used to use korean air when I could transfer chase points but I have used up all the points there. It was easy to fly anywhere in asia with them. What's a good place to look for just flights to asia in general that can transfer from chase and amex as I have the most points with those. I can also supplement with citi, MB, and capital one points if they share a partner. I know ANA for japan but I like taking trips to thailand/vietnam/china/korea too.
