I'm looking to take a spontaneous trip for a long weekend. The date is flexible and the destination can be anywhere in the world. Is there a site that would allow me to search airfares within a date range, while keeping the destination parameters open?
Sure. Skyscanner.net can do that. Just pick your departure airport and type in "everywhere" in the destination field. Then, below in the dates, pick either "Whole month" or "Whole year" and click on the Search button. Have fun!
