If the previous slide didn't sell you on carrying multiple rewards cards, perhaps this one will. Sojka points out that the most efficient way to maximize travel points is by performing the "double dip," that lucrative, if elusive, consumer strategy. The double dip is the practice of achieving twice the rewards miles on one purchase.
