Ya the Google earth app will allow you to plot the flight route on a spherical earth. You can compare this to the flight route on a FE gleason map. I don't suggest people use a Mercator projection map because no one claims that to be a true representation of the earth. You will quickly see the flight routes make perfect sense on a FE map. You will also understand why we don't fly over the middle of Antarctica to get from Buenos Aires to Perth (even though that is the shortest path on a sphere.) It's impossible because antartica is is an encircling ice/landmass, not a continent at the bottom of a sphere.
