Escape

If money, more than the exact destination, is the deciding factor on where to get away on your next rip, the Escape web site can help you find the good deals.  You enter your departure airport and the dates you want to travel, and Escape will map out destinations and color code them with dark green being the cheapest to dark red being the most expensive.  Click on a city and all the flight options are displayed, cheapest first, and you can apply various filters to hone in on your best option.
