One thing to add to this is that the a380 as well as 747-8 burn significantly more fuel per seat than their modern equivalent twin jets (a350 / 787). Last I checked the a380 burnt around 25-30% more fuel than a 787/a350. Putting more modern engines onto the a380 might give it another life line.
So in short: no economies of scale vs twin jets plus it being hard to reliably fill such a large plane are stopping jumbo jets.
- willyt 9y agoThe specific Rolls Royce engines used on the A380 were developed specially and were a leap in efficiency at the time the aircraft was introduced. The Dreamliner and A350 use engines that are of the same technological level, but the airframes are cheaper to operate because they are made from composites and so are 20-30% lighter per passenger.
