The linchpin of OW is Rod Eddington, the CEO of BA. BA has equity stakes in QF and IB, and with Eddington's having previously been MD of CX, he knows most of the major players in CX, Swire and CITIC. Where BA goes, so do the others.

The far more likely scenario is that KL will get pulled out of wings, and pulled into OW.
