This is the second post in a monthlong series that started here. Each post will take about two minutes to read and may include an action item that takes the reader another two minutes to complete. I am writing this for an audience of people who know nothing about frequent flyer miles, and my goal is that by the end, you know enough to fly for free anywhere you want to go.

In just a few days, you’ll be earning hundreds of thousands of frequent flyer miles, and you need a place to put and track them.
