The idea behind Scott’s Cheap Flights is pretty simple. You sign up, choose which airports you want to fly out of, and subscribe to receive emails with fare deals to destinations within and outside of the continental U.S. that depart from airports on your list. They use a combination of software and human flight searchers to find and evaluate flight deals and choose the ones that are the best value for subscribers. So whether you want to fly to New York or Australia, chances are you might find a great deal.
