Which aircraft are most commonly used for long-haul or transatlantic flights?

Boeing 747, 777, and 787 are commonly used for long-haul or transatlantic flights due to their specific design characteristics and capabilities. These aircraft are engineered to cover long distances efficiently, offering the necessary range, capacity, and amenities that passengers expect on long flights.

The Boeing 747, often referred to as the "Jumbo Jet," has a significant passenger capacity and a long range, making it ideal for international travel. The 777, known for its advanced technology and fuel efficiency, is also tailored for long distances and less crowded airports. Meanwhile, the 787, with its composite structure, provides enhanced fuel efficiency and improved passenger comfort with lower cabin altitude and better humidity levels, making it particularly suitable for transatlantic routes.

These aircraft also typically feature multiple cabin classes and amenities that cater to long-haul travelers, contributing to a more pleasant flying experience over extended distances. In contrast, the other options presented are generally more suited to shorter regional flights and do not possess the range and passenger capacity required for transatlantic journeys.
