I realize this is quite an inflation on the surface for those who only got KE miles with credit cards/transfers, but if one buys premium cabin tickets on KE and is a KE Platinum or Diamond in the new program then those customers may actually be better off. The old program did not have elite mileage bonuses while the new program does.
I still can't believe they are ending the lifetime program. These changes, especially the elite program, appear to better align with DL Skymiles and Skymiles has a lifetime program (just not at 500K), 1MM for Silver and 2MM for Gold.
