In the AFR today
Interesting that he talks about Adelaide - Brisbane.
QF Mainline have been operating quite consistently with the Alliance E190s and VA have been using Alliance Fokkers on the route as well as their 737-700s (they have done this for a while with their previous 700s rather than the potential new all economy configured birds).
Add Jetstar to the list and between the three you'd imagine it's a quite saturated market already., especially if QF and VA switch back to 737 (assuming there are birds available).
