The day of the week you fly can affect the rates. Before I joined DVC, we usually went Thursday to Tuesday. I didn't have any problems getting good airfare for those days. When I joined DVC, we started going Saturday to Friday so that we only had 1 weekend high point night. Saturday morning is difficult to get a good airfare, lots of people start their trips then, including cruises. This May trip has been the worst. The 9:30 flight we usually take has been sold out, the 11:30 was around $700 roundtrip, dropped to $311, then back up to $751 and just by luck on Wednesday night when I checked it, it dropped to $183! Keep trying, they make adjustments frequently. I checked for December, it's $311 for morning flights even though almost all of the seats are open when you look at the seat diagram.
