The speculation is natural. Boeing and Embraer have had several commercial agreements, mostly on the defense side but also in eco-research. But as yet, there hasn’t been a tie-up involving the successful E-Jet program.
Don’t look for anything soon that would be a meaningful response to the Airbus-CSeries deal.
Boeing needs a response in the 125-150 seat sector in which the 737-7 MAX languishes and with which the CS300 competes.
Boeing has no product offering in the 100-125 seat sector. Embraer doesn’t need Boeing’s help here. The E175-E1 continues to sell and it meets US Scope Clauses.
The Embraer E2 program’s first delivery is April next year.
Embraer isn’t about to proceed with a new airplane program in the 100-150 seat sector, which is Boeing’s product gap.
