Part of the schtick is to be vigilant checking the online sites. When I'm looking for airfare that suits my budget, I check almost constantly all the travel sites/airline sites, even several times a day. It did finally pay off for me this time. I was looking for something within reason for the first of March and I usually get this all squared away in late December, but no good rates were out there. I was starting to panic a little, (my room is all reserved at WDW) when yesterday I started plugging in my times/dates and something came up that wasn't as cheap as the past, but I figured by what has been showing up lately I should jump on it. Long story short, already TODAY, that same fare/flight etc. has gone back up $60! I'm so glad I "jumped" yesterday, I would have kicked myself if I had not purchased the tickets.
So, keep hounding the sites and good luck.
