Honestly, I've been throwing in any sort of route, LAS-ATL, MSY-MCO, etc. mostly major cities. So I guess that's the reason. I originally was trying to find a flight for my parent's anniversary using my skymiles, MSY/JAN-LAS, but also entered HOU,BHM,MEM,ATL to LAS and tried hotwire. All were out of luck. I told them that Sin city might have to wait until later in the year. Never realized that I have to book about a year in advance to get the Skysaver.
