This is the twentieth 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.

I’ve covered how to earn miles and the redemption options for miles.

Part I Europe
Part II Asia
Part III Africa/Middle East
Part IV Australia/New Zealand
Part V Central/South America

Europe is an absolute award chart bargain compared to Aeroplan's mileage requirement for Asian travel. After Aeroplan's summer 2013 devaluation, its award chart for travel to Asia became very expensive relative to other carriers.

Sadly, United’s recent devaluation and Delta’s unprecedented double devaluation brought Air Canada Aeroplan miles in line with the likes of United and Delta.

A few months ago, Bill wrote a great piece titled Beware Phantom Award Availability at United.com. It's true that United.com occasionally lists Saver award space that just doesn't exist and that you can't book online or by phone.

I've just come across the opposite: phantom non-award space.
