Estimate your air fare cost months in advance anyone know the website ?

I saw on a morning show a website that you are suppose to be able to get an idea of what your airfare will be months in advance. It was not any of the main sites as travelocity, etc . I am going July 2 through the 9th to Orlanda for a dance competition. I am already staying at a host hotel, so I just need airfare. So far $222 is the lowest I have found. Anyone know of this air fare estimator website? Thanks
