A380 or 747 production re-start is impossible economically and thus a non-starter. Neither is anyone going to design a new cleansheet VLA in A380 range in the next 20+ years for one or two customers (EK+BA).

Since the A380 was developed, there has been just as much fuel burn reduction on the airframe side as the engine side in my opinion and I'm an engine nut: 1. Wingtip treatments 2. CFRP wings. This is a huge deal vs. the 777x, A350, and 787. 3. Electrical subsystems (maintenance cost reduction and c...Jump to post

They want a new plane, but EK does not want to spend the billions your suggestion would take. They want Airbus to spend those billions.
But how much would development cost? Would EK share the risk? If not, I don't think Airbus would develop such an airplane.

That doesn’t really change the market value of planes. It just means airlines “lucky” enough to get brand new 787s at a heavy discount stand to make quite a bit of money in sale-leaseback deals.

For a type with a relatively modest order book, the decline in A339 values is concerning considering how new the global fleet is. These transaction costs are only part of the picture, we know from the Boeing results that they took a charge of over 4 billion on the 787, that is compensation and disc...Jump to post
I've seen several posts on the supposedly prohibitive cost of the flight crew's salaries to the total cost of a given flight. But is it so?

If the aircraft aren't owned by QR, but QR are paying leasing fees on them, then the argument that QR are trying to cut capacity because they've over ordered (which they're not, as they've returned grounded aircraft to operation and leased other aircraft in) or trying extort money from Airbus as so...Jump to post
Well, if you believe the Qatari version of the story the QCAA will gradually remove the remainder of the A350's from service and ground them for safety reasons.

Right, but my main point was that the A330NEO wouldn't be a completely new type in the sense that current A330 pilots would be able to fly both versions as far as I know, whereas the 787 would be a completely new type altogether.

At about 5500nm, the 78X carries ~1-2T more payload than a 251T A339, based on the competing payload-range charts on respective ACAPS. Winds are a different story, but the 78X cruises faster as well.
