What does "PAX" stand for in the context of air travel?

In the context of air travel, "PAX" is a commonly used abbreviation for "passenger." This term is essential in the aviation industry as it helps flight attendants, pilots, and operations staff communicate efficiently about the number of individuals on board a flight. It streamlines discussions about seating, safety protocols, and service requirements. Understanding this terminology is crucial for anyone working in or with the airline industry, as it allows for smoother operations and helps ensure that all passengers are accounted for during boarding and service processes. Unlike the other terms, which relate to financial transactions, operational processes, or performance metrics, "PAX" specifically and directly pertains to travelers on the aircraft.
