What is the speed of the A321 NEO during cruising?

The cruising speed of the A321 NEO is approximately 521 mph. This speed is typical for modern commercial jets, reflecting a balance between fuel efficiency and the operational requirements for traveling long distances at high altitudes. The A321 NEO, being a member of the Airbus A320 family, benefits from advanced aerodynamics and modern engines designed for optimal performance and fuel economy during cruise flight.

In this context, the other choices are not representative of the A321 NEO's cruising capabilities. Speeds significantly higher than the actual cruising speed, such as 590 mph, would not be sustainable given the aircraft's design and operational limits. On the lower end, speeds like 240 mph and 230 mph are considerably lower than what is expected during cruising, as they are more characteristic of approach or landing speeds rather than cruising altitudes. Understanding these parameters is essential for safe and efficient operation of the aircraft.
