MH, Sri Lankan, JL and a couple others updated so far from what I can check, CX is not.
So far, although long routes pretty much don;t make sense with these award rates, AS for short haul and to experience business is super value, specially hopping countries in Asia (and probably EU too), yet to make some crafty multi-city itineraries but found quite a few flights I can take.
For Medium haul I think Avios is the best and for long haul, probably AA/JAL JMB
