Well, I will have to do this journey soon and I don't know which airline to choose: KE or SU. I will need your help here fellow flyertalkers!

As far as I can see:

KE: better product, better lounges, longer journey (around 20h outbound and 24h inbound with a stop at ICN), better planes (747 and 330)

SU: shorter journey (outbound 12h30, inbound, 12h30), smaller planes with no sleepers (320)

I would tend to go with KE... then comes another consideration: with which journey would I make more miles flying C? I am currently FlyingBlue Ivory and I don't know where to find this information.

Thanks for your help!
