Went Sydney to London on QF1 In June, could not fault it, service was 100% and it was full vey full, crew said its always like this, so I doubt the smaller Dreamliner will take the route, Not that it could anyway. A380 will be around for along time, Maybe the Neo version will come, but I don't think QANTAS will buy it, 777-900/1000 will be there next purchase for the none stop AU/UK service. Still squeeze some more from the poor souls in economy class to make it viable.
