The Department of Transportation will no longer require airlines to accommodate for "emotional support animals" as they do for trained service dogs. No more guaranteed free flights for comfort cats and dogs, therapy monkeys or miniature horse companions.

The DOT said complaints by passengers with disabilities, inconsistent service animal definitions, fraudulent representations and animal misbehavior drove the change in policy. Also, disturbances brought about by requests to transport "unusual species of animals onboard aircraft," have compromised the public trust in recognized service animals, the department said.

In 2018, a woman in Newark, N.J., tried to get her peacock, Dexter, onboard a United Airlines flight. A woman and her emotional support squirrel were booted off a flight out of Orlando, Fla., later that year.

No more crazy squirrel lady on airlines!
