According to EU regulations, which of the following is categorized as a potentially disruptive passenger?

The categorization of a potentially disruptive passenger is primarily based on behaviors or circumstances that could lead to disruptions during flight or at the airport. In this context, the option regarding a deportee, inadmissible person, or person in lawful custody represents individuals who may pose a higher risk of causing disturbances due to their legal status or emotional state.

Deportees and inadmissible persons may have heightened stress or agitation associated with their situation, making them potentially more likely to react violently or disruptively. Similarly, someone in lawful custody might be restrained but could still exhibit behavior that endangers the security or safety of the flight and other passengers.

The other options do not carry the same inherent risk of disruption. For instance, a passenger with a severe fear of flying might require assistance, but this fear does not necessarily translate into behavior that disrupts the flight environment. Additionally, a traveler with a small pet typically adheres to regulations and may not cause any disruption. Frequent flyers with airline loyalty usually have a better understanding of flight protocols, making them less likely to exhibit disruptive behavior.
