Okay here is an addictive game from Lufthansa to test your geographical nouse of airport location from around the world. It only takes a few minutes to play and it is worth giving it a go, just to find out how little you know of the world's geography. My highest totla is 24,500 so far so good luck in beating that (actually that score is pretty bad)
