Tend to agree with zorn. Consistence is the key for busy people who plan their travel well ahead. I was flying with AC for almost 15 years, always been a big fan and supporter... until they started introducing changes without announcing or announcing on a short term when I couldn't adjust my travel plans to satisfy their changing requirements. Then I learned how little they cared about my inconvenience and dissatisfaction. This is what I'd call being inconsistent and what caused my loyalty to move away from AC. Hope they will improve in the future.
