I wonder whether that's a similar line to 'Impulse will never be more than the 10 717s they have now', or 'J* will never fly international'. It's what you tell someone to keep them happy and compliant. Are there shortages of crew at Qlink at the moment? Are guys and gals leaving for DJ? Is this a way they can keep them a bit longer? Dangle the carrot of the big shiny jet?
When they're parked on the tarmac in Qlink colours pushing back on their first revenue services with former Dash drivers in command/ F/O seats, then you can believe them. Prior to that however.......
