gregandkelly63 - I have spoken with several people in the travel industry and they have all told me the same thing. Airlines don't open a new plane for booking until the one currently open fills up. When they open a new flight they want to sell the first 50% of the seats fast so they can insure profitability and a shot at another full plane. After 50% of the seats are full the prices continue to rise until the last ticket is gone. The flight you saw at $440 was probably just opened that day, and the first half of the plane won't last long. The only hint that a new flight will open soon is when you're online looking at flights and the red print comes up stating "just 7 seats left" or 5 or 3. What that means is another flight will open soon and you need to check multiple times a day. It's a pain in the butt but it usually pays off if you're patient. The only thing about the entire system that bugs me is that every time I'm on a plane I know someone paid twice as much as me, or less than I did!!! Good luck.
