Is It True That The Boeing 777X's Engine Costs More Than Some Private Jets?

Is It True That the Boeing 777X’s Engine Costs More Than Some Private Jets?
Boeing’s 777X aircraft is powered by the General Electric GE9X engines, which are among the most expensive components in commercial aviation. Each GE9X engine carries a list price estimated between $40 million and $45 million. Given that the 777X is a twin-engine aircraft, the total cost for engines alone ranges from $80 million to $90 million per plane. This figure surpasses the price of many of today’s most advanced private jets, highlighting the extraordinary expense associated with these powerplants.
The GE9X’s high cost is attributed to its status as the largest and most powerful commercial jet engine ever developed. Despite being slated for commercial service six years ago, the engine has yet to enter regular operation. The 777X itself remains uncertified, with its entry into service now anticipated next year. These delays have been exacerbated by broader challenges within the aviation sector, including ongoing geopolitical tensions between the United States and China, which have disrupted Boeing’s delivery schedules and affected its order book in the Asia-Pacific region.
Engine Costs Compared to Private Jet Prices
To contextualize the GE9X’s price, it is instructive to compare it with the cost of leading private jets. Models such as the Gulfstream G800 and Bombardier Global 8000 have list prices of approximately $72 million and $78 million, respectively. Even accounting for potential discounts on large orders—which are seldom publicly disclosed—the combined cost of two GE9X engines still exceeds the sticker price of most new private jets.
There are exceptions, however. Customization and luxury enhancements can significantly increase the price of private jets beyond their base values. For instance, the Gulfstream G650ER has a standard list price near $70 million, but some high-profile buyers have reportedly paid upwards of $140 million to $150 million after extensive modifications. Additionally, larger business jets produced by Boeing and Airbus, marketed as Boeing Business Jets (BBJs) and Airbus Corporate Jets (ACJs), can command prices well above those of standard private jets.
Industry and Market Implications
The substantial cost of the GE9X engines carries implications beyond mere sticker shock. Boeing’s profitability and production targets are under intense scrutiny as the company aims to return to net profitability by 2025. The delays and high costs associated with the 777X program are closely monitored by investors and competitors alike, reflecting broader concerns about the company’s operational efficiency and market position.
At the same time, rival engine manufacturers face their own challenges. Pratt & Whitney is managing a widespread recall to address durability issues with its PW1000G engines, while GE Aerospace is implementing durability improvement kits for its Leap engines. These industry-wide pressures are compounded by a sharp increase in jet fuel prices, which have doubled within eight weeks in 2026, further elevating operational costs and influencing market dynamics.
The GE9X engines that power the Boeing 777X thus represent not only a technological milestone but also a significant financial commitment. As the aircraft awaits certification amid geopolitical and economic headwinds, the true cost of innovation in commercial aviation is becoming increasingly apparent.
