New Orders Come In For BBJ This Year Boeing Business Jets have been quiet for most of the year so far but this does not mean there isn't work happening with the bespoke-executive offshoot of Boeing. Recently the airframer made the announcement that it has received orders for four BBJ 737 Max aircraft from various customers. Of course all of them are undisclosed customers at this stage. As successors to the original BBJ family, the BBJ 737-7, BBJ 737-8 and BBJ 737-9 have CFM LEAP- 1B engines, improved aerodynamics and advanced systems that deliver double-digit reductions in fuel consumption and emissions and a 40% reduction in noise. Also range has been improved significantly.
