You make some very good points about not making fun of those who lack the proper vernacular or jargon. I'm often at a loss myself. For example, it took me a bit to figure out what ISM might be. Eventually this is clear through context but that's not so easy for everyone. So let's be kind to others.
However, what I really take issue with (and maybe this ticked other users off as well) is this fatalist attitude some OPs have on this forum and immediately call doom upon the airline. Just because they had a disappointing experience, doesn't mean they have to be so dramatic about it. And to be honest, if he really is a diamond member, he should know what is and isn't allowed.
Also, like so many other things in RichMegaCity, the CX's "travelling with children rule" is so ambiguous.
These 2 rules seem to contradict one another, because how can you be accompanied by your parents at all times if you're not sitting in the same cabin?
Seems straightforward, Accompanied means on the same flight, not same cabin.
