My family wants to take a trip from IAH to Charlotte, NC. This would require 3 tickets and one infant in lap. My wife and I have enough US Air points for two tickets (35,000 each). With the US Airways transfer bonus, I could transfer SPG to get the third ticket, but I wanted to see if I am missing anything. I currently have ~17,500 SPG points. I intend to purchase 2,500 SPG points ($70) to get up to 20,000. This will give me a SPG bonus to 25,000 for the transfer which will then have the 75% bonus from US Airways and thus enough for the third ticket. Moving past the value of the points (we do not intend to travel much on US Air), what is the most efficient way to book this trip? Specifically, I cannot book a reward with in-lap infant online. Can I book 2 rewards and then call for the third (with infant)? Also, does anyone have experience with transfering from SPG to US Air and how long does it take. The trip will be the last week of June, but we would want to book soon. Is this a quick process? This would be my first reward redemption and I appreciate any advice you may provide. Thanks.
