I honestly don't understand emotional support animals. Is it really necessary? And why is this a thing only in America?
In the western world it is a tradition for many people to keep a pet.
A dog is the animal with which man had the closest relationship until the stone age.
In families with children, the dog is often a true family member.
In partnerships where the children are already leading their own lives out of the house, the dog is the child substitute, and for many people living alone in the last quarter of life, the dog or pet is the partner replacement for the already deceased partner.
So it's a very close relationship that people in other parts of the world often do not understand, and religion has an influence here as well.
I fully understand that somebody does not want his pet to be transported in the cargo hold, because in this way countless animals have died. It is enough if after taking off the heating in the cargo hold is not turned on, or someone somewhere in the logistics chain has not reported that animals are in the hold of the flight and therefore the hold must be heated. From other mistakes of the involved personnel in the freight chain - not only intellectual high-flyers and animal protection experts work on the ramps - not to talk.
To harm people is forbidden. It is understandable that it is unreasonable for a family to transport their toddler in the hold. The same applies to people who have a close relationship with a pet. Often they really have a kind of mental dependency on the animal.
A mental dependency on an animal is seen as a human right in the West as well as a dependency on an animal because of, for example, a visual impairment.
In the US, a creative legal system makes it possible to become incredibly rich anytime you complain to a very wealthy company. Airlines are incredibly rich. Therefore, they avoid the risk of being caught by a passenger on USD $$. $$$. $$$,- to be sued for not being allowed to take his pet with them. Human rights issues also play a role here, mental cruelty, etc.
The airlines are in a very uncomfortable situation here. If they ban the support animals' support, they will be sued and they will lose. If they do not forbid them, they will sooner or later be sued as well, and they will lose as well.
The whole is therefore above all a US topic because in other continents such as Europe, for example, the taking of a dog in an aircraft cabin alone would be impossible for religious reasons. Dogs are considered unclean in religion with the highest increase and prevalence.
Quote from a well-known German actor:You can also live without a dog, but it's not worth it.
(Heinz Rühmann, actor 1902-1994)
I would be happy to pay a full paid seat on air travel for our dog to transport it in a dog travel box to save him the risk of a journey in the cargo hold. I would not expose any other family member to this risk negligently.
Unfortunately this is not possible due to the size (30kg / 70lbs).
Therefore, we have waived for now almost ten years on travel destinations which can only be sensibly reached by plane.
