You can save and scrape each and every page of your flightmemory and then import those into Openflights then you can import that into Google Maps and come up with a map that will show all your routes on a Globe, but that is as far as I have ever gotten. What I would have liked, and would still like would be to do something like Mult.dev, but that is only good for a few flights. Still would love someone to figure that one out!
