maybe CX can try to negotiate for the rights to carry domestic passengers on ADL-MEL and CNS-BNE.
Also, CX can convert CX137/6, CX157/6 to daily. Also, CX can try to launch OOL flights with KA A330 (new J/Y seats)
Also, CX can also offer F class (using 77H) to one of their existing SYD / MEL flights, probably CX111 for SYD and CX135 for MEL.
