(From the latimes.com) All airline mileage reward programs are not created equal. In fact, finding the right one is more crucial than ever. With airlines eliminating routes because of declining demand and packing each plane as close to capacity as possible, it’s getting increasingly difficult to redeem your reward-program points for a seat on a plane.
