Which of the following is NOT a type of passenger that will be accepted for travel on SkyWest Airlines?

Choosing the option related to the passenger who can fasten their seatbelt is key to understanding the safety regulations and passenger acceptance criteria set by airlines. Passengers who can fasten their seatbelt are generally considered fit for travel, as one of the essential safety requirements for flying is the ability to secure oneself with a seatbelt during takeoff, landing, and in the event of turbulence.

In contrast, the other options pertain to individuals who pose a potential risk to themselves or others during the flight. Passengers with an obvious contagious disease, those who are mentally unstable, or disruptive and violent individuals could compromise the safety and comfort of all passengers and crew on board. These criteria are in place to ensure a safe flying environment, whereas the ability to fasten a seatbelt indicates a passenger is capable of adhering to safety procedures.
