When I flew from Portland OR to Amsterdam, the route went up through canada north of Hudson Bay, over greenland, iceland, and Scotland. And approaching Amsterdam from the north. This was a straight line on a gleason map.

Also if you try to fly between Perth AU and Buenos Aires, they shortest route would be over the middle of Antarctica (7800 miles). Look at what flights they offer when you try to book it, and see if the route makes more sense on a gleason map or a globe. All the flights between South America and Australia makes no sense on a globe because they are actually at opposite ends of a flat earth.
