Who is responsible for marshaling the first passengers into the terminal building when there are 180 passengers and 4 infants on board?

The responsibility for marshaling the first passengers into the terminal building typically falls to the ground staff. Ground staff are specifically trained to assist with operations on the ground, including managing the boarding and deplaning processes. They ensure that passengers are guided safely and efficiently from the aircraft to the terminal, particularly when there are a large number of passengers, such as in this scenario with 180 passengers and 4 infants.

By having dedicated personnel for this task, ground staff can provide the necessary support to ensure that the process is smooth and organized, which is crucial for maintaining safety and efficiency during passenger transfers. Their role includes coordinating with the flight crew and managing the flow of passengers, especially when families with infants are involved, to ensure that those needing assistance receive it promptly.

Other options may involve important roles in the airport operations, but they focus on different aspects of the travel experience or are not specifically tasked with the immediate management of passenger movement from the aircraft to the terminal.
