Got my new KF Plat package via courier today. Cards and luggage tages are almost un-KF...not flashy at all, just a couple of shades of gray (platinum?) and stripe of red.
The qual and requal criteria appear much relaxed compared to the old program, at least for my travel patterns. You earn 10 "Sector Points" for each domestic segment in J, meaning one needs only 6 round trips in KF First to reach Gold (viz 10 in the old program IIRC).
Other new benefit appears to be a BA-stye "Family Account" where all miles earned by family members can be pooled into the head of household account.
Now if they can only get more international service...
