Ok so all the talk here is NJS and Impulse - you are forgetting two other QF subsidiaries namely eastern/sunstate sitting in the background with very solid and now increasingly combined infastructure..and....what's more appealing to QF is that the crews are even cheaper than impulse.
It would not be a crazy thought that the impulse 717 Jet operation is wound up, with impulse crews operating on the new skimpy services. EAA/Sunstate given Dh8-400's or even the jungle jets to operate MEL-LST, BNE-MKY etc.
There are other players in the field !
