I'm trying to redeem the Asiamiles one-world multi-carrier awards chart for up to 25,000 miles in J (160k points).

My current route is HKG-LHR-MAD-LIM // SCL-MAD-HKG which is around 25,871 miles according to GCmap. Any chance there is a 5% leeway in terms of miles, or will I immediately be bumped up to the 25,000-35,000 bracket (190k points).

I haven't been able to find any awards on shorter routes...
