Yes KD is going, a 300 is coming in to replace this. CGN suffered from low load factors so that isn't surprising.
WW need to find a way to make CWL more profitable in the winter, as it is very lucrative in the summer.
As for fleet renewal I heard its going to be more like 2014 in long term planning, and the size of the a/c will be around the B738 territory but of course no decision on manufacturer.
