TK's U class earns 0% on UA, and my UA Star Silver benefits appear to be pretty much worthless (unless something happens in IST that results in massive IRROPS, I guess), so I may as well credit this ticket to somewhere--anywhere--that'll possibly be useful for me someday.

Yes, maybe that is M&S, but maybe there's something else--for example, I visit South Africa periodically and Voyager miles could be useful for in-country hops. (Alas, U earns nothing in Voyager, either.)

Any suggestions? I thought the community here would have an idea. (Yes, it's a TK-related question, but I assume the TK forum is more interested in the M&S program and wouldn't know about crediting to other *A programs.)
