Here’s a little secret to saving big on airfare, courtesy of the New York Times Magazine. When you fly into an airport that is mainly controlled by one airline, like Memphis, Newark, or Dallas, it can be pretty pricey. For instance, Des Moines to Dallas is $375. But if you booked it to LA with a stopover in Dallas, the price drops to $186. All you have to do is just not get on the connecting flight. This is the “hidden city” trick.
