You are mvpg right?
So in Z class you get 150% eqm and 350% rdm. If you fly during the double miles promo, you get 450% rdm instead.
Don't forget that if you connect a TPAC flight to an intra-china flight, the intra-China flights always seem to book into C, so you will get extra 100% eqm and rdm for those legs.
