I mean miles/points that will NEVER be used. I assume this is what airlines record as "Breakage" in their financials. But this then opens the question as to how a program knows the miles will never be used? Is this because of inactivity in an account? Presumably in your friends situation the account is active, i.e. continually building points and would not be classified as breakage. The reasons as to why the miles/points will never be used is what I am trying to determine.
