I am planning out MSP-PEK-BCN-MSP in J and/or F with my wife and kiddo to visit in-laws in China, and my cousin in Valencia, Spain for next April or May. Have 126K AS, 380K UR (probably more like 600K by that time), 404K AA (and probably more by then). What I don't understand is which airlines would take my kiddo (born February) as a lap infant on award tickets (I'd be willing to pay a nominal surcharge), and how to actually get that done. Don't want to show up at the airport and then not be able to board. It gets really tricky with awards where I fly on partner metal. Can someone point me at some resources?
