Which of the following is true about deaf passengers?

The statement regarding deaf passengers that is considered accurate is that they must be escorted by someone known to them. This provision is primarily to ensure the safety and comfort of the passenger during the flight, as effective communication is crucial in emergencies or in navigating the airport environment. Airlines often implement policies that require assistance for passengers who may have difficulties communicating or understanding safety instructions, making an escort important for their security.

In general, passengers who are deaf can travel unaccompanied, particularly when proper accommodations, such as clear communication aids or support from airline staff, are provided. However, some airlines may implement specific guidelines or recommendations for those who may need extra support or assistance, influencing the requirement for an escort. Priority seating typically serves other passengers with disabilities but does not universally apply to deaf passengers. Furthermore, deaf individuals are fully accepted on flights without restriction, as there are no rules prohibiting their travel.
