I bought, on the IB website, a LIM-MAD-LHR-MAD-LIM ticket, all in J. Long-haul segments operated by LA; European segments operated by BA and IB. But all flights sold on IB code.
I am a frequent flyer with BA (Executive Club), LATAM Pass, and Iberia Plus. I have status with BA and LA, but not with IB.
To which programme should I credit these flights in order to maximize point earning (including status points)? I assume safest bet is IB (since itinerary is all IB-coded and IB-ticketed) but is there any way of knowing exactly how many reward and status points I would get through each of the three fidelity programmes?
