Austman, FYI....

When travelling through Europe to Australia, you have to include it as 3 continents (meaning even if you are flying on the same plane through Asia, you would STILL have to include it). Similarly if one is flying through LAX with a connection from SYD to LHR, you'd count North America as one continent too. So if y ou include Australia, North and South America, Europe....you would have to add Asia as the 5th continent!
