This guy has a lot of great information about advanced traveling (and the philosophies that form when you experience ways of living life that differ from the one to which you’re currently accustomed). His latest offering describes how he spent $500 and a few hours applying for credit cards that gave him an estimated $12000 worth of airline miles.

I’m one of the weirdos who adores the process of flying, so this is a hugely attractive system for me. Again, it’s more based towards the segment of the population with no consumer debt, no interest in consumer debt, and for those of us who pay attention to the excruciating details. I’ll plot my progress as the miles start pouring in.
