Is this better than itasoftware Matrix? I used it twice this year to build more complicated itineraries, including layovers/stopovers or having just one leg (Germany-nyc) be business class on an a380 for only $500 more. Try playing with it. The advanced controls are very powerful, for example to find layovers, so less than 24 hours (so you don’t incur a likely stopover fare add-on), you can do something like “maxconnect: 1440; minconnect: 1000”. I’m in fact typing this from a 20 hour layover in Vancouver!
