I have only slightly been able to piece together an answer to my question, but a more definitive answer would be appreciated!
I have 2, possibly 3 economy trips to the US coming up in the next 3 months. 2 are booked through AA with the trans-pac flights on QF metal and the internal flights on AA (and eagle), my QF number is entered on both of the bookings. The third trip isn't booked but likely will be booked through AA again with my QF number in the booking. If i credited all 3 to AA, i know this would go a fair way to achieving AA Plat (probably better to do a challenge). But then i wouldn't be able to use my QF SG status for the 3 trips (which is great for lounge access, seat selection(saving money for good seats internally in US) and any problems that come up). Unless there is some way that i can have my cake (QF SG) and eat it too(get AA Plat status)?
I've calculated the 3 trips get me 520 QFF SC's, which is 180 off me getting WP, but my year ends 31 August, and I won't have time to do any status runs plus I personally would rather gain AA status as I think I'll be travelling to the US more and possibly moving there at some point.
tl;dr Can i use my QF SG status while earning AA status?
Thanks for any and all thoughts!
