GE Aerospace has announced that United Airlines has selected 300 GEnx engines to power new Boeing 787 Dreamliner aircraft, under an agreement that also includes additional spare engines.

Announced on 16 February 2026, the order will increase United Airlines’ 787 fleet to more than 200 aircraft powered by GEnx engines.

Mohamed Ali, President and CEO of GE Aerospace Commercial Engines & Services, said the agreement continues a long-standing relationship between the two companies. He noted that the order will position United as the largest GEnx operator globally.

Long-standing engine supply relationship

GE Aerospace’s relationship with United Airlines dates back to 1968. The airline currently operates a wide range of aircraft powered by GE Aerospace and CFM engines, including CF6, GE90, GEnx, CFM56-7B, LEAP and CF34 engine types.

CFM is a joint venture equally owned by GE Aerospace and Safran Aircraft Engines.

Engine technology and operational performance

GE Aerospace states that the GEnx engine family uses advanced materials and technologies designed to improve durability and increase time on wing. The engine also achieves a reported dispatch reliability rate of 99.98%.

The GEnx engine has accumulated more than 70 million flight hours. It currently powers approximately two-thirds of Boeing 787 aircraft in operation and is the exclusive engine for the Boeing 747-8 aircraft.

Production outlook

Following this agreement, GE Aerospace reports that firm future deliveries of GEnx engines now total nearly 1,800 units, excluding spare engines.
