Has anybody tried this? It's free.
The way i have been using this is to use FlightAware to get a kml file, then save to your computer. Then go to flysto.net and upload the kml file. Then i suggest you use the cockpit view to see the terrain you flew over, sunlight corrected for time of flight AND see TRAFFIC you encountered!!!!
You don't need pilotaware track data.
You will be amazed.
