Why is the road distance from Athens to Istanbul longer than the flight distance?
The road distance of 757 km is about 35% longer than the 561 km straight-line air distance, because highways follow terrain, coastlines and existing infrastructure rather than a direct great-circle path. Aircraft can fly close to the shortest route, which is why the flight from Athens to Istanbul covers less ground distance than the equivalent drive.
