Create flight itineraries and be notified if the price changes with the Yapta Tagger. The program is tied to most of the major online travel agents and keeps track of your specific travel plans as you visit, let’s say, Orbitz or Travelocity. Enter your travel plans in Yapta’s My Trips and get notified if the price goes down.

You can configure Yapta to give you a heads up if the price falls below a certain price. The site claims that many price changes occur within hours of a ticket purchase, and you can often get a refund on them. If you’re off on travel often, check in with RefundPlease to get email notification on price drops within 30 days of purchase.
