The easy of use, focus, and overall money savings aspect to this site is genius. The way they categorize the length of travel VS pay, along with the actual air line is genius.
On top of the visualization and dissemination of a lot of data, the ease of actually paying for a flight is top notch. Kudos!
The ability to sort by "Agony" is damn funny. I have to say their visual representation of all of the flights available from takeoff to touchdown, while being entirely unique (looks like a Gantt chart), is incredibly intuitive.
