I'm curious to know just what makes one think that they have to give 30 days notice to change an award program? I believe that most programs state that terms are subject to change.

Let's all keep in mind that the airlines offer these programs as an enducement for you to choose oen airline over another, and then remain loyal to that airline. This is not the same as a contract which is where I think some of the comments to date have inferred.

But then again,this is all my opinion.
