No itchy, not that naive at all.
The seat maps showing allocated and free seats are freely available in Sabre on link. Although you cannot "direct conect" sell the seats, if you load the seat request as a 3RQST element, often they will come back KK in Y.
If not, if you are an Agent in good standing with EK (and we are) a phone call to Res or Sales usually does the job.
With a Skywards number, it is even easier.
I just went into the seatmap of EK412 29MAR SYD AKL, and over 25% of the economy compartment seats are showing as allocated, NOT blocked.
As for being stale itchy, I have been stale for years but work bloody hard to make sure nobody has any reason to take a piece out of me and find out!
