Be aware. There are magical mappings from marketing airlines booking class to operating airlines booking class.
In my example, SA's M class (100% if SA operating) was converted to ANA's U class (70% earnings, but 1.5 route factor resulted 105% premium points earning).
In worst case, a cheapest fare earns 0% miles and premium points.
And, ANA couldn't tell you a conversion scenario before actual crediting.
