There did seem to be some "panic activity" from CX about a year and a half after the new system as they saw people no longer qualifying for status. Not sure if this translated to reduced revenue, but the way they were giving gratis requalifications sounds like it didn't initially go as planned. They also seem to be more generous with requalifying people who are just short on an ongoing basis now.

I've expressed this previously, but the new earning patterns meant earning status from J class has become easier, and Y class is harder. So in all likelihood those who are captured by CX due to their job - not much change in their behaviour. For those who were able to get status flying from their own pocket, if they could see status was no longer attainable, then they were "set free". I know I have been, and my discretionary spending has gone to many other airlines that would have likely stayed with CX. Plus, CX has lost the data that they would have held on me before.
