Both the Airbus A319 and A321 are built on the innovative design principles of the A320 family. They feature a digital fly-by-wire system, a significant advancement over the traditional manual controls found in many other aircraft. This system uses computers to interpret pilot inputs, enhancing safety by adding redundancy and reducing human error. Additionally, the introduction of a sidestick instead of a yoke offers pilots more cockpit space and comfort.

Inside the cabin, passengers will find a single aisle with a typical 3-3 seating arrangement in economy class. Business or first-class sections usually feature a more spacious 2-2 setup. These configurations ensure passenger comfort across both models, maintaining a consistent experience within the A320 family.
