The 787 does not exclusively fly PER-LHR so poor comparison. It’s not comparable to SYD/MEL to London.
Agree with Rated D. The science and data have to make sure that this is acceptable and safe rather than just hearsay that some one flew PER-LHR once on the 787, therefore flying anything significantly longer is acceptable/sustainable.
Anecdotes from Pilot isn’t science.
Suspect we won’t have to worry about sunrise anyway for some time. Talk is that Boeing are not interested for 12 aircraft. The ME carriers buying over 200 of the 777X may have something to do with it.
The A350 is also looking like it will struggle to make the distance with the payload required by QF. Sure they will blame pilots rather than have egg on their face but who cares.
A380s looking to be slowly replaced from 2022-23 with the new type regardless.
