Travel time saver

Nowadays, everyone (okay, almost everyone) purchases their plane tickets online. I have been using Expedia Travel for a long time. But after they started charging $5 Booking Fee, I began a tedious process of first finding the itineraries on Expedia, then go to the airlines web site to book the ticket. As I was looking at plane tickets for Thanksgiving travel (going to Chicago!) today, I learned about

Kayak.com
(Similar web sites like SideStep, Yahoo! FareChase)

Basically, the travel comparison tool collects info from major travel (Expedia), discount (CheapTickets), and airlines web sites. It saved me a bunch of time! Jen is happy!
