- If the passenger has a severe mental disability that prevents him or her from understanding and applying safety instructions.
- If the passenger is both blind and deaf, thereby preventing the possibility of communication with the crew.
- If the passenger has a motor-based disability that physically prevents him or her from participating in an evacuation. Most paraplegics and people with paralysis or who are missing both arms can therefore travel without a travel companion. However, a travel companion is mandatory for most quadriplegics.
A disabled or reduced-mobility child can travel alone as an unaccompanied child if:
- he or she is physically capable of participating in an aircraft evacuation,
- he or she is able to understand and apply safety instructions.
The travel companion must meet the following requirements:
- Be over the age of 18 and autonomous*.
- Not taking care of a disabled or reduced-mobility passenger while also taking care of a child under the age of 4 (on flights in France and its overseas departments and territories), a child under the age of 5 (on international flights), or another disabled or reduced-mobility passenger**.
