I recently took a trip to Sweden, there was a connection through Philadelphia, so I turned my GPS on for that segment. I did try on some of the other segments but I was in the middle of the plane but even my new Garmin 60CSx was not capable of keeping a lock.

There are a couple of sites out there to translate your GPX files into a google map route, one of those is Walking Boss. I ran across this site because the author had written a ruby gem for processing gpx files in Ruby and I was looking for something like that for my Hiking Trails website.

This is a map of the trip, you can't show airport to airport because they want you to turn you electronics off for landing and takeoffs.
