Hundreds of years of contract law contradict your understanding--especially when you're talking about a nonessential, luxury good/service like travel and frequent flyer programs. Anyone buying miles or taking a credit card to get airline miles should be aware that the language that an airline "may, in its discretion, change the rules, regulations, travel awards and special offers [of this program] at any time with or without notice" is pretty standard stuff. Despite any blogger's screaming about devaluations without notice, the airlines are within their contract rights to do so.
Now, whether such devaluations are good business practice is a different story.
