Perhaps you should look at it not as NJS losing a large chunk of their business but 200 + crew potentially losing their jobs!?
I know us NJS QFlink crew would like to keep the jobs we have, especially here in the West where we've been operating for QFlink for 10 years (our anniversary is next month) If the contract was to go to jetstar, I would hope that QF would keep current NJS crew employed under the Jetstar/Impulse banner, after all many of us have been doing it a long time, know our passengers and the routes well. EBA negotiations are about to start again - will be very interesting!
