Since I am transferring points, this does make a lot of sense. SPG gives 5000 bonus miles for every 20k, so 20k points to 25k miles. Apparently, it is cheaper to fly business using Alaska, but more expensive to fly in first. (AA is 135k RT)

Also, any upgrade options for CX using miles? I do know I can do a one class upgrade using 50k using asia miles, which sounds stupid to do...
