Since its introduction in 1988, the Airbus A320 family has evolved to include three main variants (A319, A320, and A321), differentiated primarily by size. After the launch of these aircraft’s enhanced neo versions, the A320 family grew even more in popularity. Due to new engine options and the addition of Sharklet wingtip features, the A320neo family boasts 15-20% greater fuel efficiency and additional range compared to the original models.
