Johnny Jet is going to a conference in Tennessee in a few weeks and is going to have to hop through a few cities, and he's not really thrilled with that. So he discovered that if he added an extra flight back to LA, he ended up with a cheaper flight. He's thinks it's because he added a Saturday night stay and he didn't return from where he originated. He not only pays less, but he gets more frequent flyer miles. So, if you're traveling multi-city, always check if the price will drop if you close the triangle.
Johnny also found a great app called Image It, which will allow you to communicate in other languages by using pictures. Available in both iOS and Android.
