If you are going to travel C class try not to do it on AC ( even codeshare) as you do not get the COS bonus. If you fly D on LH ( same as C on AC) you get 25% COS bonus which counts towards your status. </font>
That's kinda chicken feed. KL gives 100% CoS bonus that counts towards status (NW gives 50%). KL and NW give pretty cool elite bonus of 125% so a paid BC ticket accruing to KL gives you 325% base miles, 200% of which are qualifying. NW is 275%, 150% qualifying.
