Is Shenzhen Airlines a large or small airplane

Shenzhen Airlines is the abbreviation for China's Shenzhen Airlines, which operates different types of airplanes, including large and small aircraft. SZL currently operates the Airbus A320 series of airplanes, which are medium-sized narrow-body passenger planes for short- and medium-haul routes. In addition, SZC operates the Boeing 737 MAX series aircraft, which is also a medium-sized narrow-body passenger aircraft. These airplanes are usually considered to be medium-sized airplanes and are not considered to be large airplanes. Large aircraft usually refer to wide-body airliners, such as Airbus A330 and Boeing 777, which are suitable for long-haul routes. Therefore, SZC mainly operates medium-sized airplanes, not large airplanes.
