A data point would like to share on BA earnings with DONE4, and happy to discuss particularly on the AA domestic sectors
Wasn't expecting both AA coded and operated domestic flights to earn with distance-based instead on revenue-based. Understood the earnings with AA vary from ticket to ticket. Ticket was issued by CX and made roughtly 8 changes on the flight date from time to time so far i started my first sector. HND-DFW-JFK-LAX-DOH are basically considered as "transit" given I booked everything to connect within 24hours, but not sure if that's the reason(if so it would be rather interesting).

Lastly, both AA flights get credited to my BA account roughly one day after the flight, and the QR LAX-DOH even gets credit while I'm mid-way to DOH , which i consider that's the fastest earning even happend to me

My routing is
OSL-DOH (AY code operated by QR)
DOH-AKL (AY code operated by QR)
AKL-SYD (QF code operated by QF)
SYD-HKG (AY code operated by CX)
HKG-SIN (CX code operated by CX)
SIN-HND (JL code operated by JL)
HND-BKK (JL code operated by JL)
BKK-HND (JL code operated by JL)
HND-DFW (JL code operated by JL)
DFW-JFK (AA code operated by AA)
JFK-LAX (AA code operated by AA)
LAX-DOH (QR code operated by QR)
DOH-DUB (QR code operated by QR)
DUB-DOH (QR code operated by QR)
DOH-OSL(QR code operated by QR)
