Background: My s.o. is with AA so sometimes I concede to fly AA (or other Oneworld partners like BA, JL) if the price is right. I am currently UA's Premier Platinum and want to keep at least Premier Gold (50k-level) with UA. The purpose of joining Oneworld FFP is to credit the Oneworld miles to it and, if possible, obtain mid-level 50k status for complimentary selection of "more space" economy seats. Below are the responses to the questions. Any help is appreciated. Thanks!
