CX offers no upgrade certificates.

Why does CX not adopt an orderly program of upgrade certificates to bring justice for loyal passengers and even more loyalty from Marco Polo members?</font>
The idea is quite simple. Because CX does not believe(I guess) that it is their duty to provide so called "upgrade certificate" for simply flying frequently. Their stance is "if you want to travel first class, buy first class tickets".
Besides, when you start issuing all those "certificates" like many third world carriers

, it becomes difficult to police their use.
In my view, CX provide sufficient perks for Diamond members even without such certificates. And, I would
disagree that they do not have orderly upgrade hierarchy system in place.
Sq345 mentioned silver member with B/N 001 gets upgrade prior to Diamond with B/N 002. I strongly do not think so. There have been many discussion before, and CX would upgrade those Diamond => Gold => Emerald (or silver).. or whatever order that has been pre-determined.
So, if you DO want to take advantage of their system, the idea is simple. JUST FLY ON FULL FLIGHT as a diamond member, and you'd probably get the upgrade. If the flight is not full, then so what? You've just paid for the class you travel.
