We're going to Puerto Rico in October so we've been shopping around for some great deals. So far, I'm really in love with flights.google.com for it's searching capabilities. For instance, you can enter the date you want to leave, followed by the return date and click search. Instead of being given a hard to read, unsortable list, you're given a map of the world with pinpoints to all the airports that detail the price you would pay to fly from your current location (or closet international airport) to their airport. It really is game breaking! What sites do you and why? What do you like about them?
