Speaking of SWS, I learned something today. If you book a flight with points, you can actually get a refund of points if the flight gets cheaper later on. We booked a trip we are going on around Christmas with points. It wasn't the flight I wanted, so I have been checking into the "change" menu on a regular basis to see if it the ones we really wanted to go on get cheaper. I rebooked a couple of weeks ago to something marginally better, but still not ideal. Well one I was looking at it today, one of the legs of the flight showed it was about 2000 points per person cheaper than it was when I booked it. So I went through the "change" process for the exactly same flight, and low and behold I got the points back.
