Is this remotely do-able with HUACA, or will it never ever happen, not in a million years? I have enough US miles and nearly enough UA miles (plus some AS miles to bridge anything else ) to get me and my daughter somewhere warm for Christmas in Y, and it turns out that HKG/BKK/DPS are easier to get to on miles than CUN, GCM or PVR. Plus I could actually squeeze CDG in as well. (This requires the UA booking be round trip, with a stopover.) Yeah. And yes, I know, it's Y. If I come upon a brace of miles between now and when I book, I'll change accordingly. Also, is booking a minor on one set of miles in one program and me on another going to be a huge bucket of FAIL, or do-able?
