In Ryanair security terms, which of the following refers to individuals other than passengers?

In Ryanair security terminology, individuals other than passengers are referred to as "Crews." This term encompasses all airline personnel who are involved in the operation of flights, including pilots, cabin crew, and ground staff. Understanding this distinction is crucial, as crew members have specific roles and responsibilities that differ from those of passengers, particularly in the context of safety and security protocols on board.

The other options do not accurately capture the broader category of individuals who are not passengers. For instance, while "Vendors" may refer to third parties who provide services to the airline, they are not typically involved in the operation of the flight itself. "Guests" can be ambiguous, as it might refer to anyone accompanying passengers or visiting airport facilities, but does not specifically denote operational staff. "1A" does not correspond to a recognized category of individuals in security terms and is likely a designation or label rather than a proper classification for people involved with the airline.
