This issue has some excellent articles on the various aircraft production programs and what is doing well and what is not. It also gives some insight into how some programs like the 737MAX evolved. Boeing favored a clean sheet design but the customers particularly American forced them into the MAX.
Programs doing well include the 737 and A320series. Narrow bodies are in demand. Wide bodies are hurting for sales. A380 is still barely breathing even with Emerites order. The 777x and A330-900 are not strong. 787-900 and A350-900 are the only solid programs. 787 production going to 14 a month. One of largest 330-900 customers may be getting ready to cancel and switch to the A350. Not sure where that leaves us and the program. Airbus still hoping for a large order from a Far East airline to put the program on solid footing.
Overall narrow body sales are extremely strong and wide body sales are well below expectations.
