What is the maximum seating capacity of the A319 aircraft?

The A319 aircraft, a member of the Airbus A320 family, is commonly configured to accommodate various capacities depending on the airline's specific layout and needs. Spirit Airlines typically utilizes a high-density configuration for its fleet of A319s, which allows for a maximum seating capacity of around 145 passengers.

This capacity can vary based on how airlines choose to arrange their seating, but the standard high-density seating layout effectively maximizes the passenger load while maintaining safety and comfort standards. The choice of 145 passengers aligns with the configuration that Spirit has adopted for operational efficiency and cost-effectiveness. In contrast, options reflecting higher capacities have not been recognized as standard configurations for the A319 within the context of Spirit Airlines. Thus, the choice of 145 passengers accurately represents the typical maximum seating capacity for this particular aircraft as utilized by Spirit Airlines.
