In my opinion *A rules are clear:
"*G can take an extra 20 kg (44 pounds) where the weight concept applies or an extra piece where the piece concept applies.
Some airlines do not offer this benefit on individual flights but only on connecting Star Alliance flights."
LH / LX / OS are still different *A airlines , even if all belongs to LH Group.
But I am not surprised , that they do not respect own rules.
*G is loosing sense, if the main *A airline are trying to circumvent the rules and privileges (by creating subsidiary airline (like 4U), or by not offering additional baggage allowance for *G on light fares.)
