Hi all, I will be taking a trip this summer with my two kids. I am contemplating the option of buying two tickets and using US miles for the third. This would mean a separate PNR for one of the passengers, although of course all of us will be booked on the same flights. Will this present any problems? I suppose when I book the award via US Airways I don't need to be telling them it is for a child. But once I book, should I or should I not call UA and let them know? I think I don't need to tell them anything. No one should care that we are on separate PNRs. Right? Thanks!
