Pot-bellied pigs, miniature horses and monkeys could be allowed to travel with you on planes under new British transport rules.
The guidelines are part of a draft manual on equality for disabled people travelling on commercial passenger planes, Daily Mail reported on Tuesday.
Animals should be allowed on flights if they are used for "emotional support" by their owners, the manual states.
Transportation officers would have to determine whether the animal is permitted on the plane by running through a list of guidelines.
"A passenger arrives at the gate accompanied by a pot-bellied pig," the manual states. "She claims that the pot-bellied pig is her service animal. What should you do?"
According to CNSNews, it continues: "Generally, you must permit a passenger with a disability to be accompanied by a service animal.
"However, if you have a reasonable basis for questioning whether the animal is a service animal, you may ask for some verification."
"Finally, if you determine that the pot-bellied pig is a service animal, you must permit the service animal to accompany the passenger to her seat provided the animal does not obstruct the aisle or present any safety issues," the manual adds.
Pot-bellied pigs can grow as large as 300 pounds. They can be trained to open and close doors and use a litter box, the Mail added.
