Re: NZ CEO hints longer range 787

6T MTOW boost would be great for 789/10 performance. However, it would also benefit from tank capacity increase. At current 101 Tons, at the edge of the envelope it will max out on fuel while still before hitting the MTOW.

I think it would be doable with <200 pax. The problem is, even at max load, they would max out fuel capacity, which is 101T. LHR-PER is pretty much at max fuel. To fly 600Nm extra, they would need another 5-6T of fuel. Maybe Boeing is able to increase max fuel like Airbus did with A350ULR?
