One detail with the Korean Air Morning Calm Premium Club (500,000 miles level): it seems to require flying all of those miles on KE, not even Skyteam partner miles are taken into account.
Doea anybody have information to the contrary?

Requirement for Morning Calm level:
Members who have flown more than 50,000 miles on Korean Air (or more than 30,000 miles, with mileage accumulation in excess of 20,000 from our partner companies)

Requirement for Korean Air Morning Calm Premium Club:
Members who have flown between 500,000 and 999,999 miles on Korean Air
