fakecd - Your email doesn't work!
So I'm going to post my email to you here -
Hi
Guy Betsy here...
Can you please give me your exact dates/ flightnumbers / routing for all your flights. The way I see it is to rebook your M class ticket sectors onto your original YVR-HKG sector with the B class sectors. And then cancel the existing M class sectors with the YVR-HKG M class sector that you don't want...but that might cause CX to ask why you are doing this.
But if the dates that you want between HKG-SYD - HKG-YVR is still available on M class, then rebook this reservation on to your B class record PNR. CX will not ask you to 'show' your ticket before they do it, all that they ask is if you are allowed to make changes. Say YES. They won't ask you for ticket numbers as the ticket numbers on the B class ticket is already on file.
Plus some tickets on CX mix classes especially on tickets between North America and Australia.
If you need me to do the whole booking for you, I would be happy to.

Wayne Tan
