I was playing with Kayak and found a feature that’s interesting to explore – a map of where people want to travel. You enter an airport and it will show you the top 25 searched for destinations from that airport.

It’s fun to compare, say Atlanta, Ga., with Vancouver, B.C. There are even substantial differences between Washington National and Dulles.

Route lines are color-coded so that you can pick out which routes are more expensive. One nit I would pick is that the color coding is relative to the other destinations on the current map. On one map a route that is red could be $250 and on another map it could be $1,000.

If looking at the map gets you in the mood to travel, you can limit the results to those that fall in your price range or timeframe.

The travel business generates so much data; it’s great to see someone putting that data to good use. Now they just need to come up with a catchy name for it. Travelocity isn’t using Dream Maps anymore.
