It doesn't need to be non-stop.

The problem is that ultimate rewards --> Korean can only be made for "family" so I don't really know what to do as my sister-in-law isn't within that definition.

I must confess I don't know what AS or DL (Delta?) miles.

The issue isn't availability on Korean -- it's that I want to transfer points --> korean miles but then I can't use the miles on anyone but direct family as far as I know...

The AA flights are 75k miles one way (with stops)...
