Introduction
December 19, 2019, © Leeham News: Qantas Airways declared the Airbus A350-1000 the winner for its project Sunrise last week. After two years of competition with Boeing’s 777-8, it was the preferred aircraft for what many say is the holy grail of airline routes, the Sydney-London route.

  • When Airbus adjusts the Maximum Take-Off Weight and fuel capacity of the A350-1000, it can fly the routes Qantas asks for.
