Thanks - doesn't seem to be very clear then!

Also can you do open jaw redemptions if the mileage charged is the same (e.g HKG - NRT, KIX - HKG) or is it 2 one ways again?

Amazing how unflxible AM redemptions are versus BA Avios - have 250,000+ AMs but question whether that's more valuable than my 150,000 avios
