Tripit is most people’s pick for travel planning and sharing these days, its main selling point being the ability to digest flight and hotel reservations automatically, although it doesn’t have much in the way of visualization capabilities. However, it does have an API supported by a lot of third-party apps, so I can turns my TripIt plans into eg. flight maps in OpenFlights, which supports complete network maps as well as individual trip maps. And for extra hipster points, you can even export from OpenFlights to Google Earth!
