Last year saw Airbus and Boeing push single-aisle deliveries. Airbus was in its second year delivering the A320neo and its first delivering the A321neo. Boeing started delivering its MAX8.
Switching from the previous version to the new version has its challenges at the assembly plants. Airbus had to contend with engine supply issues as well. But as we can see, both managed to ramp up as the year progressed.  Airbus had a blowout December as engine availability started to catch up. Similarly, Boeing’s best month was December.
With big backlogs stretching out over seven years, both OEMs are going to speed up in 2018. The transition from the old model to the new should accelerate.
The OEM official O&D information is current through November. Here is what it looked like then.
Airbus had close to 30% of single-aisle deliveries in the neo models. It looks possible that in 2018, A320neo deliveries might exceed the A320ceo. Given the growing popularity of the A321neo, there is likely to be a push on that program this year, too.
Boeing had only the MAX8 for delivery and it accounted for just over 10% of the single-aisles. This year we also expect to see a boost in MAX8 deliveries compared to the -800.
Of interest is the dominance of the -800 on the overall 737 program. Whereas Airbus sees the A320 models account for about 61%, the 737-800/MAX8 account for over 92%.  Once the year-end data are published we might see some changes in the numbers.  The 2018 transition at both OEMs will good to watch.
