It's actually borderline fraudulent for CX to be selling tix for flights they know they will not operate beginning March 29. For example, SFO-HKG, CX is still selling three dailies from March 29 on. The only question is when they will cut two of those, thus matching current operations.

If you buy a ticket on CX right now for travel March 29 or later, you are effectively buying into a schedule change.
