- Boeing 777: Commonly configured in a 3-3-3 layout in economy class, which can feel a bit cramped on longer flights.
The 787-10 also features larger windows with electronic dimming, providing a more pleasant ambiance.
Operational Costs
Cost efficiency is a major factor for airlines when deciding on aircraft. The 787-10 is designed to be more fuel-efficient, which can lead to lower operational costs over time. Here’s a comparison of the fuel burn:
| Aircraft | Fuel Burn (per seat) |
|---|---|
| Boeing 787-10 | Approximately 5.5 liters/100 km |
| Boeing 777 | Approximately 6.8 liters/100 km |
The 787-10’s lower fuel burn per seat can significantly impact an airline’s bottom line, especially on routes with high passenger loads.
Conclusion
In the end, both the Boeing 787-10 and the Boeing 777 have their strengths and weaknesses. The 787-10 shines in fuel efficiency and passenger comfort, while the 777 excels in range and payload capacity. Airlines must weigh these factors based on their specific needs and routes.
