I flew enough on OW this year to surpass GO requirements but yet I chose to align with another FFP, and the topic under discussion relates to why some people are foregoing MPC into other FFPs. In fact, CX's GO and DM pool was enlarged twofolds by the merger of KA as there are lots of PRC-HK commuters, so its not exactly too hard to enter the GO and DM universe anymore.

This thread is about CX's "revenue optimization" which devalues the FFP in the long run. As the GO and DM elite universe enlarges, the perks increases operating expenses and/or enroaches potential revenue. Your "savings of HKD 1-2K per week" is a very attractive potential revenue stream for CX. One could imagine the potential revenue CX can receive if they revised the guaranteed seat fare buckets upwards starting from K. This is exactly what they did with the mileage upgradeable fare buckets two years ago.

Keep in mind elite tier benefits can be easily taken away, but take years to be added back. What you're enjoying right now could be history next year. Without active discussion and feedback on the market, airlines can take FFP perks away without a second look, so thats why Flyertalk exists.
