it will be to allow SFO to go daily
SFO is already daily (and very successful according to QF, would be surprising to see them drop a huge chunk of capacity there).
Incorrect. San Fran is 6 per week and daily over December / January only. QF also needs to get rid of the unreconifgured 744's from its system as the product is simply not up to scratch. (For that matter the Skybed 2's need to be replaced as well so hopefully the 789 Suite goes onto the A380's as well)
The first route no doubt will be used for training and familiarisation. Id think a short run up to SIN and back would be on the cards to maximise the opportunities to rotate crews through. It'd also showcase it to plenty of pax whilst doing the run.
For training runs the routes that makes sense are SYD-PER, SYD-MEL and SYD-AKL. QF are all reconfigured A330's into Singapore, aside from the 738's to PER, so I can't see them messing with that. If anything the route in Asia to put the 789 on is the second SYD-HKG service because that allows for Premium Economy on both flights out of SYD.
QF will probably start up MEL-SFO with 789 and with that extra capacity they could probably drop SYD-SFO to 789 too. If it grows further then they could look to add BNE-SFO.
I think you'll see MEL-DFW before you see MEL-SFO. My bet for first 789 long haul route to be BNE-LAX-JFK. That allows for the older 744 retirements and keeps the latest premium product going into JFK. It also allows room for AA to come into BNE.
789 is far too small BNE-LAX...IMO this will be a 747 route for a while until QF decide on either a A359 or 77X. If QF really are going to put a premium heavy config with a lower seat count, the ratio of passenger classes isn't right for the route which supports 747 capacity, even if they increased frequency with either additional QF services or AA on the route, a potential double daily 789 would match economy demand and allow for a small amount of growth beyond what the 747 holds, but be too premium heavy.
