If you enjoy travel, finding discount air fares can sometimes be a full time job. Sure, you can subscribe to email alerts from a variety of travel sites. However, they will only give you information about which airlines are giving them a substantial commission. Happily, help has arrived in the form of a little dog called "Browser." He is the featured search dog on Airfare Watchdog.

Unlike other airfare sites, which tend to have preferential agreements with specific airlines, Airfare Watchdog lets you search for the best possible fare on any airline. You can sign up for email fare alerts, and view the routing maps of various airlines. The site has a daily blog and a message forum. Check it out!
