I'm looking for a flight search engine that will search all domestic (or foreign travel too) during a specific time frame by date and price. I've been on Kayak and it shows by month.

I have a open mind to where I can go for a trip. I'm looking to plug in a date and then let the search show my where in the world I can fly during those dates and for how much. Anyone know of such a site? I keep searching but can't seem to find a site that does this. It is the same, plug in City name, then the next, etc.

Thank you for your help.
