Well that was fun.
Just got off the phone with the Concierge who just told me that some flights booked right in front of me by a check-in agent in YQB less than an hour before (driven by a cancellation by AC) were not ticketed.
They showed as HK in the Cowtool, but she assured me that they were not ticketed. The downside was that the YQB agent had put us in J (original booking was 2 pax - Flex M FP) because he saw no availability in Econ. Ticketing just 'fixed' the booking and stuck the two of us back in Y.
We're currently at the top of the e-up list but we will see.
I'm still surprised (and not sure that I believe) that I could show as HK and still not be ticketed. I learn something new everyday, I guess.
