Note, however, that VIE-LAX is operated by OS, so it will be OS rules that apply. Right now it looks like a *G on an Economy Light fare gets 1x23kg in baggage allowance but the LH Group is moving in the direction of allowing no status exemption on zero-bag tariffs, which would mean no baggage at all regardless of status (LX gives no baggage to anyone on a Light fare, and LH allows 1x23kg "as a gesture of goodwill, for the time being" in tiny print).
