DL SM are only good for use outside of North America. Don't originate in or go to NA.

To use DL SM, you have to get yourself to a good gateway airport, like ICN, NRT, HND, KIX, etc. Then book the DL SM flights to/from there. For example, 80K one-way J TYO or ICN to JNB, CPT, etc. (Asia to Africa) is a pretty good deal and almost matches UA 88K one-way J from NA to Africa.

DL SM is not meant for use within North America, as it's designed to rip off those who originate in or go to NA. In NA for SkyTeam, use VS miles. Outside of NA, there are some good uses for DL SM still.. for now.
