Maybe I'm not understanding OW status. I'm AAPlat for 2017 but moved to UK and need to switch to BA because there's no way I'd fly four AA flights per year, they're all BA (crap earning rate for economy). However, I think I'm understanding that I can only use my OW Sapphire if I add the FFP with which the OW status is earned, correct? So if I want to change to BA I basically have to go back to nothing and start over and throw away my Sapphire? Or can I fly BA FFP and show the AAPlat card for those benefits?
