The one I usually use is Orbitz, but I'll tell ya this, they all seem to have the same prices no matter what site you go to. You could try Priceline.com, that's a site where you tell them how much your willing to spend and then they find flights in or around that range, If I'm not mistaken though, you have to go whenever they tell you to, I don't think you can pick what your times are, I've never used it, but a friend of mine has, you'd have to go to the site and check it out. Good luck and happy hunting!!
