Don,
Just answer the questions?
I have no idea what you are talking about wrt the A345. The market has spoken on that airplane, and it was sentenced to death along with the A346.
If you are implying that passengers are always more profitable than cargo, then I simply disagree, especially if you are referring to Y class. But maybe hauling back-packers is EK's business model, if so, good for EK A380s. CX's business model is hauling premium passengers and cargo. Y class is only there to provide an aft CG for aircraft efficiency (sarcasm).
