Introduced into service in 2015, the Airbus A350 is a remarkably efficient aircraft. With two engines, like most contemporary commercial jets, and 300 to 350 seats, the plane can fly up to 9,700 nautical miles (18,000 kilometers) nonstop. The A350 has a 40 percent smaller noise footprint than the aircraft it was designed to replace (e.g., the four-engine Airbus A340). Airlines are using the Airbus on a wide variety of sectors, including ultra-long-haul routes such as Singapore-Newark and shorter ones like Paris-Addis Ababa.
