One-Stop Travel Search

2004 saw an increasing amount of attention given to travel search tools, particularly those that simultaneously search multiple databases. In fact, Yahoo acquired FareChase in July and launched a beta in September.

The article: Search engines revved up for one-stop travel service takes a look at some of the new travel search meta search engines including Kayak (they just announced a deal with AOL), Sidestep (download required), Mobissimo (just out of beta), and Quixo.

UPDATE: Pam Parker reports that Kayak is about to launch a ppc ad campaign to help bring traffic to their site. See: Kayak.com Readies New Year PPC Campaign. I've used Kayak for several months and particularly like its use of "sliders" to help modify and focus result sets.
