Which type of passengers requires a special announcement in the terminal to notify other passengers of their circumstance?

The need for a special announcement in the terminal typically arises from the unique circumstances of certain passenger groups. Prisoners and their guards travel under strict security protocols, which necessitate privacy and awareness among the airport staff and other passengers. An announcement regarding their status helps maintain security and ensures that the travel process is handled discreetly and appropriately.

In contrast, while unaccompanied minors, VIP travelers, and expectant mothers all have specific needs or considerations during travel, their situations do not require the same level of notification to other passengers. Unaccompanied minors may have rules around assistance or supervision but do not necessitate a public announcement. VIP travelers might receive special treatment or accommodations privately through the airline staff, and expectant mothers may need certain considerations but again, not a public alert. Therefore, the unique and sensitive nature of transporting prisoners justifies the need for a special announcement.
