boarding
Boarding refers to the process of getting on a vehicle, such as an airplane, train, or bus, to begin a journey. Passengers typically present their tickets and identification before entering the vehicle. This process ensures that everyone is accounted for and ready for departure.
In the context of travel, boarding usually occurs in designated areas, such as a boarding gate at an airport or a platform at a train station. The boarding process is often announced through loudspeakers, and passengers are called in groups to streamline the flow and minimize delays.
