Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights
Why is there no interface that allows searching for flights without specifying <i>exact</i> dates? All I want to do is fly from A to B to A. Maybe stay a week, maybe two. I'm flexible - it doesnt have to be exactly N days starting on the M'th.<p>Even services that "allegedly" advertise they have that, still require manually clicking every day combination.<p>I'd fly more often <i>if it was easy</i>. The few times I tried, it would be just faster to drive than go through all possible 900+ day combinations.
