United Airlines is tightening the leash on its rules for customers traveling with emotional support animals.
Starting March 1, passengers must provide confirmation that their emotional support animal has been vaccinated and properly trained to behave in a public setting.
A veterinarian must also confirm that the animal won't "pose a direct threat to the health and safety of others on the aircraft or cause a significant disruption in service."
And, as always, customers with emotional support animals need to give United 48 hours' notice to the Accessibility Desk and a letter from a mental health professional.
The stricter rules came just days after a woman tried to take a peacock on a United flight. The airline said no.
United isn't the only airline implementing tougher emotional support animal guidelines. Delta recently announced a tougher update to its policy that will also go into effect March 1.
