This flight is maybe an idea to fly when global flights comes, it is 16 Hours and 20 minuts long from doha to Auckland and back it Will take 1 hour and 20 minuts longer (so 17 hours and 40 min). Qatar airways uses a 777-200LR.
Imagine you must fly 16+ Hours and sit down al that time. But you Will see the half off the world.
Will you foy this route in IF/real world?
