As the latest variant of the Airbus A320, the Airbus A320neo family plays a key role in short and medium-haul operations for multiple different US carriers, with the jet’s fuel efficiency proving to be its principal advantage over competitors. One variant in particular, the Airbus A321neo, offers additional passenger capacity over the smaller A320neo, which makes it incredibly popular with US operators looking to add capacity to high-demand routes, especially during the peak travel months.
