What is the maximum range of the A321 NEO?

The A321 NEO, which stands for New Engine Option, is designed with enhanced fuel efficiency and advanced technology to offer a significant range for short to medium-haul flights. The maximum range of the A321 NEO is up to 4,000 miles, making it suitable for transcontinental flights and some longer routes. This capability is achieved through its optimized aerodynamics, lightweight construction, and modern engines that provide greater fuel efficiency.

The other options do not reflect the performance specifications of the A321 NEO. For instance, 3,000 miles is below the aircraft's capabilities, while 590 miles is more typical of regional jets or turboprop aircraft, and 39,000 miles far exceeds the range of any commercial airliner, indicating a misunderstanding of aircraft performance metrics.
