Hey there, you're reading an outdated post! The updated series from April 2015 can be found here.

This is the nineteenth post in a monthlong series. 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 flier miles, and my goal is that by the end, you know enough to fly for free anywhere you want to go.

Here are the basics of using aa.com for award bookings.

This post is part of a four-part series. In Part 1, we looked at the mechanics of the AAdvantage program. In Part 2, we looked at the mechanics of a stopover, including how to use them to get free oneway trips within North America. In Part 3, we valued specific AAdvantage awards. In Part 4, I’ll put a number on one AAdvantage mile.

In this post, I'll explain why I value one AAdvantage mile at 1.77 cents per mile, but your value will be different.

1) American Airlines has two region-to-region charts, one for travel on American Airlines and one for travel on its partners.

Below is a list of all possible North American international gateway cities when using American Airlines AAdvantage miles. Why are these important? As we'll learn in my series on the value of AAdvantage miles, when traveling on an AAdvantage award from North America to any other region, a free stopover is allowed at the North American gateway city.
