Hi Kristin,

I have done the same thing the other way round (ICN-HAN and then SGN-ICN) - November/December 2009
The loads were roughly 75% (Asiana - OZ).

I do not have access to the loads you are looking for...but i wouldnt bother too much.

You can take OZ or KE...they have plenty daily flights...its not an issue.

Have a pleasent trip!
