Boeing 777-300ER Price & Production Status
How much does a new 777-300ER cost?
The list price for a new Boeing 777-300ER in 2023 was estimated at approximately $402-420 million. Actual transaction prices are often lower due to undisclosed discounts, volume purchasing agreements, and offset arrangements common in the aviation industry.
Current list price and market value

Boeing 777-300ER Technical Specifications & Comparison
What is the range and fuel efficiency?
The 777-300ER has a maximum range of 7,370 nautical miles (13,650 km). The aircraft is powered exclusively by the General Electric GE90-115B engine, the most powerful commercial turbofan engine ever built. Aerodynamic refinements introduced during flight testing reduced fuel burn by an additional 1.3% compared with the original 777-300ER specification.
777-300ER vs 777-300: key differences
The 777-300ER is the extended-range variant of the 777-300. It features a higher maximum take-off weight (352,000 kg vs approximately 300,000 kg for the standard 777-300), more powerful GE90-115B engines, and strengthened landing gear and fuselage. The ER variant also includes additional fuel tanks in the cargo hold.
777-300ER vs 787-9: which is better?
The 777-300ER offers higher passenger capacity and greater cargo volume than the 787-9, making it more suitable for high-density hub routes. The 787-9 is more fuel-efficient and provides a cabin with higher humidity and lower cabin altitude, which some passengers find more comfortable on ultra-long flights. The choice between the two depends on airline route economics and passenger demand.
The full schedule of cabin retrofits for many airlines remains unclear. British Airways, for example, has not confirmed a complete timeline for installing Club Suite seats on all its 777-300ER aircraft. Always check your specific aircraft before assuming seat quality.

Context: Why the 777-300ER matters
The 777-300ER was the defining long-haul aircraft of the 2000s and 2010s, dominating markets between Asia, Europe, and North America. Its retirement from production in 2022 marks the end of a two-decade era. The aircraft remains the most common 777 variant in active service and will continue flying for at least another 15 years due to its economics and cargo capability. Airlines are currently investing in cabin retrofits to keep the type competitive against the Airbus A350-1000 and the upcoming Boeing 777-9.
