I'm going to try to calculate again and call AS back just in case. Figuring out how AS calculates isn't easy to me. They show Miles, Bonus, and Total. I got 25,078 in Bonus column going there and 24,396 coming back. Is that all EQM? I'm not sure.
Yep, I flunked math on this assignment for sure.
Can't tell you how many times I've searched for "how to calculate AS miles."
Since BA & AA are both oneworld carries. What you earn in Mileage Plan is determined by the two character carrier code preceeding the flight number.
It doesn't matter who you bought the ticket from or who operated the flights, it is the marketing carrier and booking class that matters.
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.
