I’m not going To go back and reread your first couple of posts, but I think you were alluding to CC holders and how they are as valuable (if not more so) than customers actually purchasing seats. No where here does is there a reference to AMEX or CC spend! Please read the financial statements (in particular the 10k statement) to understand the incremental ‘value’ I must assume you are talking about. This site only refers to how to use Skymiles, which I think we are all pretty familiar with.
