Passenger

A passenger (also abbreviated as pax) is a person who travels in a vehicle but bears little or no responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle.

Passengers are people who ride on buses, passenger trains, airliners, ships, ferryboats, and other methods of transportation. Historically, the concept of the passenger has existed for as long as man has been able to create means of transportation capable of carrying more people than were needed to operate the vessel.
