I just checked the CX flight timetable for this November, and all CX163 flights are currently showing as being operated by a 777 (I am unable to see which configuration this is). It is possible that CX just updated the equipment, and it is not showing in the timetable yet. May I ask when you noticed this change? I am just asking because I am keeping an eye on the equipment for an upcoming flight in December, and CX has been updating timetables over the past week, so I am just curious as to whether CX has finally begun the final updates on their Oceania routes for NW25.
