Finally, a non-emotive and logical post. Thank you.
I don't really have any argument with what you wrote except to reiterate, that I mentioned the 787-10 for CX. The -10 is the competitor for the A339 despite being slightly larger. It is a true short and medium range aircraft, like the A339.
Those who think CX does not need an A330 and regional 777 replacement are wrong. The misuse of long haul aircraft around the region is a wise business practice for CX, but it does not cover all the regional requirements. A dedicated regional fleet is necessary.
CX will choose either the A330NEO, A350R, or the 787-10. The A330v2 would provide nice commonality of course, but the -10 would be better able to replace both 777 and A330 due to its larger capacity, pax and cargo. The A350R isn't really a regional aircraft at all, just a derated version with lower MTOW. So, that's really just further misuse of long haul aircraft.
