So, expect the earn-rate on LH group Z flights to come down very soon in Miles and Bonus as well.
it is not automatic and decision is made by each program on a combination of many factors as well as bilateral relations between different airlines, otherwise earning rates throughout the alliances will be harmonized long ago.
if you ask me, I would do the same way as A3 - give more points to C and F in exchange of giving less to discounted Y. that will help keeping their non-flying membership containing of people they receive highest compensation for when they receive credits from other *A airlines.
