It is the case only when all the sectors in your booking are confirmed. So, always include a return sector even you only need one way. Also, include more sectors when you first make the waitlist bookings. The best way is to add DAC HKG as the first sector and any busy flight like HKG JFK in F as the last sector.

They can’t ask you to issue the ticket when the outbound flights are confirmed. Otherwise, it makes you pay more fuel surcharge. Tickets originating from DAC are free from the recently added CX fuel surcharge for the whole ticket.

Just some experience to share.
