Just to bump this, I was looking today for a flight from europe to the middle east on a Skyteam airline using Skymiles... and remembered this idiocy that Delta does not publish any global redemption mileage requirements or award chart.

Delta claims to be a big global airline but cannot publish award levels for international redemptions? Every other major airline does it. (Seriously: I challenge you to name one other airline of Delta's size that does not publish this.)

It is clear that actually they can do it but choose not to. Why? Certainly not because not publishing them serves their customers... in fact it can only serve Delta. How does it serve Delta? Probably by giving them the ability to hide the redemption levels and change them at any time without any scrutiny. What an insult to Skymiles members.

Or can somebody prove me wrong by showing me where they are in fact published?
