The staff travel issue was agreed by KA guys and your management and forced upon CX staff. This won't happen again.
KA did go bust. It had nibbled at routes CX didn't want or couldn't operate profitably. 30 years later it still operates routes CX doesn't want.
As for seniority transfer, what happened to all those captains on the KA freighters when they transferred to CX. Every one of them started in the RHS.
As for CX F/O's and KA commands, the CX contract has a non poaching clause. CX pilots adhere to contracts. If that changes then you had better look out.
Your DEFO and DEC situation is your own making.
P.S. In Europe you get a 320 command in a heartbeat but most of you lot couldn't even manage that. Get real. There is no way any of you would pass the CX selection and you know it that's why you applied to KA after failing your commands in Europe.
KA is by definition " a wholly owned SUBSIDIARY of Cathay Pacific".
