Ah -- didn't see that. Okay so my post is now invalid.
A K fare is much more expensive than your normal X/V fares are.
A332 all the way!!! I haven't seen it as a 777 lately, though.
Correct me if I'm wrong, but isn't this one of DL's longest routes in their system? I know ATL-ICN/PVG, ATL-JNB, DTW-PEK/PVG probably top this, but anything else?
