When BA did that due to closing off the front cabin, they gave, in cabin, an MCO equivalent to the passengers' whole itinerary calculated in full fare, even if you were on an award ticket. ^ Then again, someone had to sue BA for an involuntary downgrade (hence the palm tree reference earlier). CX and other Asian airlines are however known to be a bit cheap in the customer service/recovery department. I'm not sure if you signed away anything but using this when writing to CX as an example would be a good start. Might want to try to see what the CX condition of carriage is. I have an awrd ticket coming up imminently and would be pissed if this happened to me.
