Can the 787 do london sydney no stop on the eastbound leg?
I recall reading that QF surveyed some frequent travellers on wether they would pay a premium for a non stop service to or from London, and they all said that a return non stop service was their preffered option.
So if the 787 could operate non stop from london to sydney, it may well be full ex Sydney, with connecting passengers from brisbane melbourne, and merely transit in Perth.
Such a service would be unique in not stopping anywere enroute except Perth.
