Qlink must be smiling from ear to ear.
ATR much better dispatch reliability.
Fuel burn unmatched per seat/km.
Less than 270nm, will not be much different time wise.
Qlink don't operate flatout as trying to extend engine life, and with the gear issues, groundings, the choice for the short routes is simple.
CBR-SYD is perfect.
Have heard the jet vs props argument for passengers and have never found a booking website that gives you that choice. No 1 is price No2 is timing and that is it.
