Is the 25% not on top of the other 25%, or in addition to the already existing 25%?</font>
I'm afraid not. From the * 25% Tier Bonus FAQ:
"Q: I am a member of bmi diamond club, do I earn the Star Alliance 25% tier bonus in addition to the tier bonus I already receive as a diamond club member?
A: No, both members of bmi diamond club and Miles & More already receive a 25% tier bonus on all Star Alliance flights. You will continue to receive this as part of your standard programme benefits."
