Along the same lines of FareCompare, FareChase claims to help you select when to buy your airfare based on historical trend data on airfare rates. FareChase seems to have a cleaner approach with a look and feel that more resembles a commerce travel site.
FareChases’s results page (limited to just a few cities in the beta version) gives a easy-to-read fare history graph, flight times with prices and a great fare prediction tool that gives you tips on whether you should buy now or wait for rates to go down. It’s perfect for those of us who have some flexibility when we travel and are price conscious.
in a the spirit of 2.0, you can currently cast your vote for your home airport to be included in the next release. What a great way to decide the order to add airports to their data… OH, and to collect your email address too. (-;
