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.

I am excited to announce a new feature: the milevalue.com Mile Value Leaderboard. Find it at the top of the page. On it, I'll keep track of my latest valuations for every major frequent flier, credit card, and hotel loyalty currency. So far, it just has three entries: Avios, Rapid Rewards, and Membership Rewards. Avios and Rapid Rewards were dissected in the last week.

Full Membership Rewards analysis is coming soon. But I've added it to the list because right now there is a 50% transfer bonus if you transfer Membership Rewards points to Avios.

Update April 1, 2014: This post was written before Southwest's massive devaluation. Now you need 70 points per dollar for Wanna Get Away? fares instead of 60. Now Rapid Rewards are worth about 1.45 cents each.

Southwest Airlines Rapid Rewards points are worth 1.69 cents per point. Unlike my calculation of the value of an Avios, the valuation of a Rapid Rewards point does not change based on where you live or your flying preferences because Rapid Rewards is a fixed-value award program.

Below is a list of every oneworld alliance flight from New York City flown by British Airways, American Airlines, Cathay Pacific, LAN, Iberia, Japan Airlines, and Qantas. I have also included non-oneworld partners on which you can book flights with Avios miles-- Alaska Airlines, Aer Lingus, and airberlin. Routes only operated by Alaska Airlines, Aer Lingus, or airberlin have an * because they can only be booked over the phone (800-AIRWAYS), which will incur a $25 fee.

The list is divided into International routes and Domestic routes.

The list is divided into International routes, Hawaii routes, and Domestic routes. Within each group, the routes are listed from most Avios required to fewest.

In Part 1, we looked at the mechanics of the Avios program and how it compared to the AAdvantage program (another oneworld program.) In Part 2, we built on the rules of the Avios program to discover what awards they imply are the best values. In Part 3, we valued 20 specific Avios awards. And in the final post, I'm putting an exact value on an Avios.
