For discriminating travelers and potential Web advertisers, a group of travel sites offers much more than just discount airfares.

Just can't wait to get on the road again? There are a handful of travel Web sites out there that are looking to be one-stop shops for those with wanderlust. Several of these sites provide information and sales on discount airfares, something almost every traveler is interested in. But these discount sites sometimes offer great deals at the expense of content and design, which means that they are none too sticky. After all, once you've found your great fare, there's no reason to stick around. Other sites may or may not be the best place for a fare deal, but they offer so many travel resources that they're irresistible in their own way. They're like travel magazines, guidebooks and booking agents, all in one.

By now, well-traveled consumers know well enough to comparison shop for airplane tickets, car rentals and so forth, so they're probably hitting most--if not all--of these sites. It can become an obsession, in fact, plugging in dates and destinations, and waiting for a sweet fare to appear.

But if you're looking for Web surfers who are willing to hang their hats long enough to take in the ads you bothered to place, you might want to consider these most well-rounded of the sites we've traveled to.
