If they are BA flight numbers, use the BA charts. If they are AA flight numbers, use the AA charts.
BA flight numbers are favourable, even if AA operated, since business class fare buckets earn an additional 100% RDM bonus and higher fare buckets earn more EQM.
BA, R & I fares earn a 50% COS bonus while C, D & J fares earn a 150% EQM bonus. The only EQM boost on AA is in full J class with a 100% COS.
When I have a few minutes, I will look at your numbers and will work them back. It is confusing that AS only shows RDM total, base & bonus which is compounded since the figure also includes COS as COS is both EQM & RDM.
