I'm trying to change the HAN-HKG segment of my HAN-HKG-YVR to the earlier KA flight of the day.

HAN-HKG was in J. If I search ITA Matrix for the earlier flight with Hanoi as the Sales City, I see that 2J is clearly available.

Called CX to make the change. They say the flight is "all sold out" for the purposes of changing an existing ticket, even though there's space available when making a new booking.

Can someone explain to me the tricks that CX are pulling here? I tried to listen to the CX agents' explanations (multiple of them!) but I never fully understood before they ran out of patience.
