I just successfully (I think) changed my itinerary tonight on CX website. Original outbound was SGN-HKG-ORD in May. I changed it to SGN-HKG-LAX-ORD in July for extra $47. If I wanted direct flight from HKG to ORD, I would need more than $22K for the fare difference. I also moved the inbound flight in November a few days ahead too. Given there have been plenty of talks about how difficult is to change the ticket, I found the process were pretty straightforward. I actually spotted a few other days change with less than $100 are available.

Now here is the strange thing. In a few minutes, CX sent me 5 eticket confirmations with 3 of them are old itineraries and 2 are new. I was bit worried so I checked the booking again on CX website. It still showed the new itinerary. I guess I need to call them to confirm?
