Who's flying CX A321 NEOs these days, Is it the ex-KA pilots who transferred to CX as STCs?
How much training did they have to do before they could fly the repainted aircraft?
I believe it's none and on the contrary they are probably the ones who signed the AR/IR for the first A320 CX pilots.
With CAD approval anything can be done, probably same with Immigration approval,
Let's wait and see what's happening next, maybe a bit of redundancy in CX so that
PR can be rehired quicker when pilots will be needed.
