This post is part of a four-part series. In Part 1, we will look at the mechanics of the Avios program and how it compares to the AAdvantage program (another oneworld program.) In Part 2, we'll build on the rules of the Avios program to discover what awards they imply are the best values. In Part 3, we’ll value specific Avios awards. In Part 4, I’ll put a number on an Avios.
