I would be surprised if QF didn't have a use for most of the Jetconnect 737 rated and current pilots. If they wrapped up JC and took the airframes home but not the pilots then instead of being 60 crews short on the 737 they would be 110 crews short.
If on the other hand they make the JC pilots mainline crew based in Auckland then the jets can do triangles through Syd Mel and BNE. The jet utilisation would be improved and the pilots would be able to fly the domestic sectors so could do more than they currently can ( 900 rather than 700hours).
