You must have gotten mixed up...
AFAIK there is no FFP paying a CoS bonus in coach.
Re: UA and LH CoS bonuses
UA pays CoS for biz and F (25%/50% - you'd get 125% / 150% of your actual flight miles credited. Not counting towards status.
LH pays CoS in biz and F (100% / 200%)- dbl./trpl. miles credited). Counting towards status with M&M.
All other bonuses are not class related.
