Nobody has mentioned the new split of Asia into North and South zones, like *A and OW. Not a good thing. "North Asia" consists of only Japan, Korea, Mongolia, so you'd think that's good, since South Asia is all the rest of Asia, other than Indian subcontinent.
BUT in order to get ANYWHERE in Asia on current Skyteam choices, you'd have to transit in NRT or ICN, thereby incurring a North/South Asia ticket, vs. a simple "within North Asia" or "within South Asia" ticket.
MH is still an option, though not mentioned on the chart. Hope it's still around! Also, China Southern might join at some point too. But nothing yet.
Here's the kicker:
"Flights within or between North Asia and South Asia on Korean Air require 50,000 miles for Coach,*70,000 miles for*Business and*100,000 miles for First Class."
Compare this to the old NW award levels of Y=20K, C=30K, and F=40K. Yuck! Especially on within North Asia--that means the 1hr15min flight ICN-NRT on KE would be 100,000 miles in F. Umm....think I'll pass!
Finally, there is no listing of intra-Asia award levels, other than on KE (and that's in the footnotes). Does that mean that NW/MH awards are still 20/30/40? I hope so!
