Over the course of a few weeks, I applied for and received 13 new credit cards that each included bonuses of at least 20,000 Frequent Flyer Miles. I was accepted for every single card I applied for, and received $102,100 in new credit that I will never use. What I will use are the 300,000 bonus miles I was awarded for accepting the cards. After meeting any minimum spending requirements, most of the cards will be unused, consolidated, or canceled over the next few years. Not everyone will be want (or be able) to emulate this challenge, but I know that enough people will that I decided to put it all out there for you. Just as importantly, many other people will be able to use this strategy on a smaller scale and earn at least 50,000 new miles within the next month.
