What is the maximum seating capacity of the A320 aircraft?

The maximum seating capacity of the A320 aircraft is commonly around 180 seats in a typical two-class configuration. This capacity can vary based on the airline's configuration choices and the layout they select. The A320 is designed for efficient operation in single-aisle scenarios, which often leads airlines to configure the aircraft to maximize passenger comfort while still maintaining a high number of seats.

While there are configurations that can accommodate more passengers, such as in an all-economy layout, the most widely recognized and standard seating capacity used by many airlines is indeed 180. Recognizing this standard is crucial for understanding the operational capabilities and design intentions behind the A320 series.
