Buy the BA flight numbers only; do not buy an AA-coded flight. Flights on AA metal (with a BA code) are just fine. For example, BA1509 in the above example will earn way more than AA193 even though it's the same physical flight.

Earnings:
EQM: 17,800
EQD: 2,390
RDM: 11,900 (plus elite bonus, if any)
