What are the different airline policies on accompanied travellers?

A companion will only be required if the passenger has a severe mental disability, preventing them from understanding and applying safety instructions, if the passengers are blind and deaf, or if the passenger has a physical disability with mobility, meaning they will not be able to participate in an evacuation. The airline state that they offer travel companions of disabled passengers discounted airfares on selected domestic flights. They will try their best to seat both passengers together, to the extent that they will ask other passengers to move so that you can be seated together.
KLM state that if you require help with things such as administrating medicine or evacuating the plane in an emergency, then you will need to arrange your own safety assistant or travelling companion.
Delta state that you can purchase an additional ticket for a companion or personal care assistant for your flight. They are required when disabled passengers are unable to understand safety instructions, or are unable to evacuate in the case of emergency.
British Airways also require passengers to book another seat if they are unable to lift themselves, reach an emergency exit unaided, communicate with staff, unfasten a seat belt, retrieve a life jacket or fit an oxygen mask.
