I am trying to maximize MQM on DL, but also keep my costs as low as possible. I have been using.http://fly.qux.us/smcalc/ to calculate how many MQM different routes will yield, and then checking the google flights function to see pricing to different cities. I like the google function bc when you enter a route, the map will show you prices to virtually every other city as well. Is there a more effecient way to maximize MQM / minimize costs (eg one app or site), or is my "trial and error" method the most thorough?
