I'm looking to pick a secondary program for an upcoming flight with LA, in case it doesn't credit to AS like it should. I'm booked in Q class, MEX-LIM-SCL-IPC-SCL-MEX. From what I've researched:
On BA, I'd earn 25% miles MEX-LIM-SCL and SCL-MEX: 2,060. (0% on SCL-IPC RT)
On KK, I'd earn 50% miles on the entire itinerary: 6,455
On QF & AY, I'd earn 100% miles MEX-LIM-SCL and SCL-MEX: 8,238. (0% on SCL-IPC RT)
On AA/US, I'd earn 100% MEX-LIM and SCL-MEX, 25% on LIM-SCL-IPC-SCL: 8,263
On AB & CX & MH, I'd earn 100% miles for the entire itinerary: 12,910.
(Couldn't find information on JJ, now that they're OW)
I travel exclusively for leisure, and am trying to accrue to AS for status. Which of these are best for retroactive credit, and which are best for a redemption on a partner airline intra-US (or suggestions on redeeming an extremely low amount as indicated above)?
