I was unaware of Yahoo! FareChase until today (yes, I am ashamed), but once I saw it I declared it the shiznit.

FareChase is basically an Ajax application that goes out and gets fares from multiple travel sites and aggregates them so you can see them all in one place. Very nice if you are like me and shop Expedia, Travelocity, Orbits and the others before buying a ticket.

And the really cool part is that you can go to Yahoo! search and type something like “flight denver to atlanta,” and when you hit the search button it will bring up the FareChase interface at the top of the search results. This kind of integration will probably make me use Yahoo! to start out all of my flight searches.

Plus the Ajax interface makes it look heckin’ smooth.

Here is an analysis of what Yahoo! FareChase might mean to the travel business from someone named Brian Smith.
