Again, you do not know the meaning of value or devalue or devaluation. You haven't really contributed anything but false info about Krisflyer redemption rate / fee and misunderstanding what devaluation means. Worth or value does not necessarily have to do with cost; this is basic English. You can have no worth as a human if you are a serial murderer. You can also place more value on a partner who supports you. In both cases, it doesn't mean you cost more or less
; the concept of value or worth is multifaceted and not just as simple as that. The lack of understanding of basic English is insane. Hilton points could be devalued if they suddenly make standard rooms not bookable. Currently, the policy is that if there is a standard room then you can use points to pay for it. If they change that policy to only allow 1 per date per hotel in the pool, that can be considered a devaluation, even if that room stays at 10,000 points. It's a really easy to follow and basic example..
