United Airlines picks 300 GE engines to power its massive Boeing 787 fleet

United Airlines has made a significant decision for its future long-haul fleet, selecting 300 GE Aerospace GEnx engines to power its firm order of 150 Boeing 787 Dreamliners. The agreement, which includes spare engines, solidifies United's position as the world's largest operator of the GEnx engine.

This engine selection is a critical component of United Airlines' broader fleet modernization strategy. The carrier plans to retire its entire fleet of aging Boeing 767 aircraft by 2030, replacing them with the more technologically advanced and fuel-efficient 787 Dreamliners. United already operates a substantial fleet of over 70 Dreamliners, and this new order will significantly expand its widebody capabilities.

A Strategic Engine Choice

Airlines ordering the Boeing 787 must choose between two engine suppliers: GE Aerospace and Rolls-Royce. United's selection of the General Electric Next-generation (GEnx) engine underscores a focus on operational efficiency and reliability. According to GE Aerospace, the GEnx offers up to 15% better specific fuel consumption (SFC) compared to the GE CF6 engine it succeeds, a crucial factor in reducing operating costs and carbon emissions.

The engine's performance metrics are a key driver of its market success. The GEnx boasts a dispatch reliability rate of 99.98% and utilizes advanced, lightweight composite materials like carbon fiber fan blades to reduce weight. This combination of fuel savings and high reliability helps airlines maximize aircraft utilization and minimize downtime for maintenance.

Dominating the Market

The GEnx engine has become the dominant powerplant for the Dreamliner, powering approximately two-thirds of the global Boeing 787 fleet. It is GE Aerospace's fastest-selling widebody engine, with over 3,000 units in service or on order worldwide. This substantial order from United further cements the GEnx's leadership position in the competitive widebody engine market.

United's firm order for 150 Dreamliners includes a mix of the 787-8, 787-9, and 787-10 variants. By powering these new aircraft with GEnx engines, the airline is ensuring consistency and efficiency across its growing next-generation long-haul fleet.
