If CX's goal is to restrict access to its lounges as much as possible, I don't think they would have a co-branded credit card in HK that allows even CX GREEN members who fly ECONOMY (on CX metal) to use their J & (even) F lounges. And, yet, they do! And this program was only launched within the last few years (post Covid), not something launched a long time ago that they are looking to cancel soon.
