Fuselage Material Carbon-fiber-reinforced polymer Aluminum
Engines 2 (high-bypass turbofans) 4 (high-bypass turbofans)
Passenger Capacity 240-300 (varies by configuration) 250-300 (varies by configuration)

Performance Metrics

When you look at performance, the 787 is designed for efficiency. It can fly longer distances with fewer fuel stops, making it a favorite for airlines looking to cut costs. The A340, with its four engines, offers unmatched power and redundancy, making it a reliable choice for airlines that prioritize safety on long-haul routes.

Range and Speed

The range of the 787 varies by model, but it can cover approximately 7,530 nautical miles. The A340-500, a variant of the A340, boasts a range of about 8,000 nautical miles. Speed-wise, both aircraft are competitive, but the 787 often has the edge in cruise speed due to its advanced aerodynamic design.

Passenger Experience

Both aircraft are designed with passenger comfort in mind, but they approach it differently. The 787 features larger windows, lower cabin altitude, and improved humidity, which contribute to a more pleasant flying experience. The A340 offers a spacious cabin, but its older design may not provide the same level of comfort as the newer 787.

Amenities and Cabin Layout

Airlines have the flexibility to customize the interior of both aircraft. However, the 787 often comes equipped with the latest in-flight entertainment systems and cabin layouts that maximize space. Here’s a breakdown of passenger amenities:
