This! It's especially good when you have flexible dates, or you want to taylor your search (eg, connect through Dallas rather than Chicago). I've also used other multi-airline search sites (kayak, hipmunk, orbitz etc), but they never have the best price available. It's best to narrow it down to a few of the best options, then go price them directly on the airline's website. It usually works out significantly cheaper.
