I'm not even an MPC member, just Asia Miles, and during a delayed flight, HKG-MNL, I requested for an upgrade using my miles just so that I could use the Wing to catch a little shut-eye, as I was very tired and bordering on sick, not to mention that I had to rush to an exam in Manila the next day (which became the same day, as the delay wasy pretty bad)

CX staff just told me to go to the Wing and rest, and I was able to catch up on my sleep (I was on my way back to MNL from FCO, so after a 14 hour flight and a day touring Hong Kong, I was definitely out of energy)

Next thing I know, I queued at the back of the economy line, and when they got my boarding pass, it was rejected, and I apparently was upgraded to J. I checked my miles the next day, and nothing was deducted. I wasn't even full-fare Y. I have no idea why I got the upgrade, but I'm grateful to CX for it, as I really needed the recline so that I could start sleeping again.

I have no idea how this happened, but I guess I looked pretty pitiful. While all the passengers around me were throwing hissy fits at the delay, I was throwing a pity-party. After all, I was a young college student who was extremely tired and feverish and weak. I guess I hit a soft spot.
