I am in this sitch. Since, April we have maintained constitutional (separate but equal) AA accounts for the sole purpose of getting miles for her; without having done that our two purchased tix on every trip would only yield 1/2 benefit (FF can only log/earn the miles on those personally flown). As it stands, by the end of the year she will have about 140k RDM (PLT thru 2/15) and I will have nearly 300K RDM (EXP thru 2/15, I did a couple small runs). Our travel plans would not have been different but had we not enrolled her separately from the git-go, that buffoonery would have cost/paper loss us over $7000 (what I value those 110k + 30k points otherwise forgone and what the street value is for ORDHKGBKK r/t is on CX in biz)...all for not wanting to reveal her email to AA. I'd say if you don't plan to capitalize on the program (i.e., you only fly once or twice), then it probably would NOT be worth the hassle.
