Since you're already Platinum Pro with AA, you might want to look at a status match with Alaska, which would give you immediate MVP Gold 75K (Oneworld Emerald) status with AS. https://www.alaskaair.com/content/mi...%3aMileagePlan. You could then decide whether to pursue long-term Emerald status with AS or with any other Oneworld program. I guess the main question is what benefits do you depend on that require Emerald status?
