I've just listed for a dragonair flt by calling the ticket reservations number from the KA website 31933888. I was also told just to go to the KA counter aisle D for check in.
When I've listed with other airlines such as swiss I also just called the reservations number in HK. That seems to work. As for checking availability
www.flyzed.com seems pretty accurate. Ask your company for user name and password.
