Although it's not a fait accompli, but if Qantas gets the ACCC over the line to take over Alliance then it will play the NJS, Network and Alliance drivers off each other to get the best deal for the shiny new things coming along in the sub-150 seat segment. I can imagine that Alliance gets all the F100s to keep the rest of the fleet going and gradually replaces them with the E190s, leaving Network as the cheap A320 operator using the hand-me-downs from JQ.
