I just checked out bing.com. Has anyone followed their suggestions before and if so, how did that work out for you? I have been looking at air fare almost daily for the past few months for the week after Easter and the prices have been crazy high. The price for the round trip flight I am interested dropped a little this week (at least it's under $400) and just today it dropped $20 from yesterday. Bing.com is still telling me to wait because there is a good chance there will be a price drop of at least $50 in the next seven days. They say they are 81% confident! I was all set to book at $349, but now I think I will wait.
BTW - for my three flights from Detroit to Orlando in 2009, I never paid more than $159 and that included tax and fees. My cheapest was $122. These Easter prices are killing me - but I do know that is prime vacation time.
