Copying a thread from Alienshe's wonderful forum, I thought it might be interesting to post here. This website tells you distances between places so you can work out how far you have travelled. http://www.indo.com/distance/
I worked out my flight distances and added them together to see how far I travelled but you could just put in the start and end places.
Canberra, Australia to Szekzard, Hungary = 18228 km or 11327 miles
Canberra, Australia to Groningen, Netherlands = 17461kms or 10850 miles.
