I've just been playing around with Vayama. Vayama provides a novel interface to searching for flights. Essentially, it allows you to enter origination and destination information by selecting locations on a map. It then shows you the results in the form of routes drawn on the map.
For example, let's say we want to fly from Seattle to Barbados. First, we select Seattle. By browsing the global map, zooming in exposes airport locations.
Here we see Seattle has been registered as the port of origin.:
Having selected Barbados as the destination, hitting select shows the results on the map:
I suspect that by mapping the results, users will be able to spot odd solutions to their flight search quite easily.
