There is little capacity in the KA TRG system to help CX pilots gain experience. In fact, this would be a gross under utilisation of resources better used training to capacity to meet projected expansion.
If KA commands where ever available to CX FOs. Those with a high core set of skills should probably only apply. There is nothing overly difficult about demonstrating a 3X ADR failure into Chongqing. But the nature of long haul flying and it's lack of exposure and sectors, aswell as cultural differences between the two airlines, doesn't make for great preparation.
Swire will play the two off against each other. The schoolgirl egos here, would see them slash their own conditions out of spite, in order to satisfy professional jealousy.
