Some where in QCC or D or B or which ever building the wheels work in they are smoking some strong s##t. Take Santiago, Joburg and Haneda just for starters. These 3 ports would average on every flight 320 plus Paxs. Unless they go to 2 services a day they will not have the same number of seats available . Haneda they can’t get more slots except between 2200 and 0600. As for the 787s doing more hours than the 747s daily , yes you can when they are new however as time goes on without massive engineering and spares support it falls apart, Qantas have neither. 17 hours a day long term is unsustainable. Secondly to do this you end up with schedules that suites your utilisation not the paxs commercial want. They have pilots training on the 747 at the moment I wonder what will happen to them, more money wasted probably.
