See the flight path between the Ohio and Rome?
I tried Google maps and does not appear two places at international level. Try to Columbus Ohio and Rome in Italy and that just does not work. How I can display two items on the map from Google that are in different countries??
Google Maps does not display flight paths. A plane does not follow a straight line from one city to another. You may be able to try to download Google Earth. You can see the real effective flight path took a flight through the airline and flight number flightaware.com 's flight tracker
