From London to sydney

Hello and welcome to the community I hope you enjoy it here,

I would recommend checking out this PDF on fuel burns made my @DeerCrusher. From what it says the 3 that you should make it in are the following with the shortest range first and longest range last.

  1. Boeing 787-8 Dreamliner - 21:08
  2. Airbus A380 - 22:11
  3. Boeing 747-8 - 23:44

I hope this helps you make your decision.
