The break even is 480; which won’t be for quite a few more years. But, bear in mind that the 747 has had decades. At present, sales of the 380 are ~2x that of the 747-8.
The other points to consider is that Airbus has worked out the kinks in making carbon fiber wings; as they have delivered 44 aircraft already. The fact that they have worked out this problem puts them ahead of the curve when they go to retro-fit earlier designs. If you can make a wing for the 380 out of carbon-fiber, you can do it for the 308, 310 ect.
Boeing’s Dreamliner is still effectively grounded - they haven’t gotten the composition manufacturing streamlined yet.
Because Boeing didn’t risk and innovate - they are behind the curve; in an industry that has very lean profit margins. Meanwhile, Canadian Regional Jets are cleaning up in the small jet market, and AirBus is ~2x the orders of Boeing in the big jet market.
Doesn’t take a genius to see where things are going.
“At present, sales of the 380 are ~2x that of the 747-8.”
what about next month? The market for the 380 just isn’t as large. There are only so many airports which can handle the 380.
Kinda curious as to why you are so down on Boeing. Is it because Airbus lost the Air Force contract.
