My mother-in-law lives near Urumqi, China.This Christmas and New Year, she wants to come see us in NYC. While she is visiting, we will see my family near MSY. I plan to book her a reward ticket that goes URC -> PEK (1 day stop) -> EWR -> long stay, perhaps a month -> MSY. The return will be the reverse, though I would love to stick a SFO stop in there (but, that may just be done on a paid ticket, since SFO > PEK is UA metal). I can't book the URC -> PEK online, so I know I will have to book this by phone. I have no clue as to how to locate the inventory on this portion, though, to plan for calling in. When I look for paid travel on the route, it shows CA flights. I've only got 88k miles, so this will be booked on Economy SaverPass availability. I have 4 of the old SWUs, though, and won't be using them for anything else. Would love to have her ride in BusinessFirst. Can I use a couple of them on the reward ticket (and, are do they work on UA metal - making the SFO return a possibility)?
