Airlines and others frustrated by the loose rules regarding Emotional Support Animals boarding flights across the U.S. are taking a stance against the growing abuse of this right. Similar to guide dogs in a way, these animals are extremely helpful for those with emotional and mental disabilities, such as Post Traumatic Stress Disorder (PTSD) and clinical anxiety. However, the system is easily, and very often, taken advantage of.

To obtain certification and proper licensing, a citizen only needs to file on the website for the Agency “USA Service Dogs” and shell out about $200. It only takes about 3 minutes. People countrywide have registered a variety of animals include snakes, cats, miniature horses, pigs, and even a kangaroo. Yes, you read that right.

There exists a growing debate on what animals, if any, should be allowed to sit with their owner in the passenger cabin. On one hand, some argue that these animals need to be there to do their job, such as monitoring events like panic attacks or flashbacks. But the number of pet owners who merely want to sit with their pets during travel or save money grows each and every year. The last time the Department of Transportation met was in 2003, leaving the public to deal with vague and outdated guidelines. Guidelines do not specify exactly which animals may serve as support animals nor does it set a standard for registering your animal. And what happens to other passengers with allergies? Business travelers, for example, can’t just take medicine because side effects may inhibit their ability to drive and/or perform well for their job.

The Department of Transportation recently met this month to re-evaluate the rules.
