Or you risk, it not going the way you want, getting credit for both programs, and then later not only having both credits removed, but even having your account suspended. I had a period when a TA that I was using would stupidly book my TK flights with another * Alliance number, I would change it to my TK number, and yes several times get credited to both programs, a couple of years later I was "audited" and not only were those miles removed, but I was threatened with having my account closed. So I really would not risk it if I were you.
