Want to travel with an emotional support dog, duck or miniature horse? Starting next month, United Airlines will want passengers to show they can behave.
The airline is setting more stringent requirements for emotional support animals, joining Delta Air Lines in cracking down on a sharp increase in such animals in the cabin. Delta complained that some of the animals soiled cabins or bit travelers.
United said the number of customers bringing emotional support animals on board has risen 75 percent over the past year.
"The Department of Transportation's rules regarding emotional support animals are not working as they were intended to, prompting us to change our approach in order to ensure a safe and pleasant travel experience for all of our customers," United said.
Starting March 1, United passengers will have to confirm that the animal is trained to behave in a "public setting" and take responsibility for the animal's behavior. Travelers must also hand over a form signed by a veterinarian that shows the animal is up to date on vaccinations and a document that states "there is no reason to believe that the animal will pose a direct threat to the health and safety of others on the aircraft or cause a significant disruption in service."
