So im trying to go to Vegas in July, i've booked myself already using United miles and am all set. My Dad is not into miles but my moms a flight attendant so hes never needed to be. With me on a guaranteed ticket however he was looking into purchasing one but id like to save him if I can. I've got 45k on US Air, and the flight I want to get him on will only cost me 20,000 miles + $35. My question is how do I do this? Can I use my miles for his flight? When it asks for passanger information I figured I can just put in his info, but then it asks for a frequent flyer number. Do I use mine, or his (which of course contains 0 miles)? Is there a way to transfer miles to him? Anyone know how to make this happen on US Air? Thanks in advance.
