Here's the updated model. Two items warrant emphasis: the A321neo continues its march to single aisle dominace, and the A330neo may be entering its heyday replacing aging out A330ceos. Notes What is behind the tremendous A321neo attraction? Orders keep coming and despite the supply chain constraints, Airbus is able to push out many monthly. We are now into the last month of the quarter and deliveries are way behind last year's, signalling the supply chain constraints. India's IndiGo continues to draw Airbus focus with its tremendous delivery rates. How long before Airbus has to add another FAL? This has to be in India. John Leahy used to show this chart at every briefing and made the point about what a great vendor Airbus is.This pattern is not to going to look as reliable going forward.

But the OEM cannot exploit this advantage because the supply chain remains constrained. It is able to stay ahead of Boeing but that's because Boeing is in worse shape. But it can't fend off Embraer at the lower end, as Embraer has a more reliable supply chain (much of it internal). Embraer will attract orders because it can deliver faster. Airbus has had several years to get the A220 program sorted, and it has not. This next chart illustrates Airbus Achilles Heel. [caption id="attachment_85486" align="aligncenter" width="580"] Airbus; AirInsight[/caption] This is not a dig at Airbus (the A220 comment is though), Airbus can't fix the supply chain on its own. The point we are making is just how much co-dependancy there is with a duopoly.
