In our four part series on helping you optimize and maximize your dollars so you can increase your travel and travel lifestyle, I talk with Scott's Cheap Flights Co-Founder Scott Keyes. We talk about how he got started finding cheap flights and grew his newsletter to over 1.6 million subscribers. We also talk about how you find mistake fares, strategies for pulling the trigger on great deals, and some of the best deals they've found. Mixing this low fare service with the miles and points we discussed the last 2 weeks, and packing of your bags that we'll talk about next week, should give you the ability to fly for low or no cost.
