I'd say both are about the same. The Qantas link one starts down in Rockhampton and then does a milk run up to Cairns (ROK - MKY - TSV - CNS). The Rex one is the same coming in from the N2 Mount Isa to Townsville run.
For an extra $20 you'd be getting points, lounge access if eligible and a slightly more comfortable aircraft if you went the Qantas option but that's about it.
Worth noting anything can happen, so if the timing is essential I'd even consider driving. It's a 4hr drive where you don't have to rely upon the airline's on-time performance.
Every time I ever have anything to do with Qantas it just reinforces my desire to NEVER set a foot on any QF plane ever again.
They are clearly world leaders in the ‘Screw your customers for the last cent and deliver as little as possible’ stakes - don’t bother asking coz I won’t answer - I just feel so much better now that I have expressed my feelings.
