Boeing 777 cost varies; new models are expensive

The cost of a new Boeing 777X is in the hundreds of millions, while older models can be found for tens of millions, but no new passenger 777s are being delivered in 2025. The 777X is awaiting certification, with deliveries expected to begin in 2026. The price of a 777 varies significantly based on the model and age, with used 10-15 year old models selling for $70-90 million. List prices for new 777s range from $330-425 million, but actual costs are affected by negotiations and order size. Lease rates for older 777-300ERs were around $450,000 per month in late 2024, while new widebody aircraft lease rates were much higher. Engine values, particularly the GE90-110/-115, have also increased due to delays in the 777X program.
