Brazil-based Embraer is waiting for Boeing to decide what to do with the 737 before it makes a decision on the E-Jets, Embraer’s CEO told Bloomberg.
Embraer may decide to put new engines on the plane or build a new aircraft.
Embraer jets are smaller than Airbus and Boeing models, but the company might enter a new market for larger airplanes.
"If there's an opportunity to maybe stretch our aircraft or do something a little bit bigger, we'll of course decide and seize that opportunity," Embraer CEO Frederico Curado told Bloomberg.
Airbus decided in December to re-engine its A320 single-aisle aircraft, and Boeing is deciding whether to replace the 737 engines or build a new model to replace the aircraft.
