I follow some travel bloggers and I'm always perplexed by their mileage accrual schemes. In this case, US Airways is giving away up to 100,000 bonus miles for people that get enough third-party activity on their plans. The author has mapped out a complex strategy to get the miles by spending $400 on various items he doesn't want or need, including a few throwaway car rentals and, of all things, a boutonniere. I appreciate that the 100K miles have an approximate value of $1,000–or more, considering that this man certainly is planning some redemption tactics to extract value–but I just don't see the utility in spending real money for what is basically store credit. Maybe if I were more of a road warrior I'd get it, but I dunno.
