So you can have a good go at calculating how much you would get for your non-AY OW flying by using the info on the AY website. The distance-based nature of the scheme (for non-AY flights) mean that short flights will earn very little in either avios or status points, even in business class, but if you do a reasonable amount of long-distance premium class flying, this should be achievable.
