I don't mind Jetstar operating on these routes, even if I don't like Jetstar per se. I would rather the QF group do it than a codeshare with someone else.
What I don't like is the way all these new routes are marketed as brand new. All the routes Jetstar have taken over have been operated by QF of Australian with in the last 5 years. They are only brand new for Jetstar, not the QF group.
