This will probably get buried, but I just want to point out that people with disabilities that have service animals have a very difficult time bringing their animal on board a flight. It is a very serious issue that politicians have made worse because they refuse to take up the issue and regulate it because regulation is bad according to one side of the aisle. There is absolutely no federal oversight for service animals. As a result, anyone can go on amazon and buy a service animal tag and affix it to a dog's vest. When a person brings a service animal (which is defined by the US Supreme Court as a dog that can do a task that the owner can not do and is not the same thing as a therapy animal which would protect against housing discrimination and air travel) into a business, legally the business owner can only ask for verification that the dog is a service animal (and typically only does this if there is no $1.99 badge affixed to the vest). It's ridiculous. Now you have people abusing the system and gaming it. As a result, the airlines have made it increasingly more difficult to bring a service animal onboard since people don't want to pay the pet fees. For housing, the animal does not have to meet the service animal designation, a dr simply needs to state the animal is a therapy animal (a therapy animal in theory can be any animal, not just a dog) and you are covered under 1970s housing discrimination laws. A dog that calms a person's anxiety or lessens depression is NOT considered a service animal, the Supreme Court said, because that is the essential function of a dog, and is not something a dog is trained to do, it just does; indeed a service animal has to perform a task that the owner cannot do by itself and is trained to do (according to the US Supreme Court a service animal is only a dog, no other animal can qualify).

While it may be good that there is little government oversight so more people (and not just the rich--bona fide service animals cost 10s of thousands of dollars) can take advantage of the benefits of a service animal, the fact that there is no regulatory body or agency that issues an accepted qualification, it has caused incidents like the above.
