CEO of Qantas, Alan Joyce, has previously said he will make a decision on the plane by the end of 2019. Specifically, Qantas would be likely to be more interested in the smaller 777-8 variant, as this would allow for the additional range required for these long flights.
But such a special flight requires a special plane, and for that Qantas has reportedly been weighing up its options between the A350 and the Boeing 777X. The trip would take around 20 hours, and would take the crown as the world’s longest flight in history. Project Sunrise will see direct, nonstop flights between Sydney and London or New York.
