OK, first appologies if this is the wrong forum, couldn't come up with a better one.

I have 120K USair and 60K continental, and want to book 3 *Alliance tickets to europe - wife and two small children. The best I can come up with is wife+kid1 with Usair and then call continental and book a toddler alone (telling them I already have a reservation on the same flight for my wife).

Is this going to work, or am I out of luck and need to find another solution?

Thanks much in advance!
