FlyerTalker ttjoseph has developed a new online tool for mileage runners to help maximize the number of miles earned on a flight. The free tool is located at http://fly.ll.cx/routemax and will show you the “most advantageous routing for a given routing rule, especially when the rule is long and complex,” writes its creator. The tool lists all the possible flight paths, with the highest mileage route at the top. You can also enter the cost of the fare and the tool will calculate the cost per mile of your trip.
