text_1: People can fly with dogs, pot-bellied pigs, turkeys, monkeys, and miniature horses if they claim that their pets are emotional support animals.
text_2: This claim has been rated “mostly true” because although passengers with emotional disabilities can travel with dogs or other support animals such as monkeys, miniature horses, or pigs, they are required to provide documentation from a mental health professional in order to do so (even if sometimes airlines accept nothing more than a simple verbal claim in allowing passage for a pet). To avoid the Wild West atmosphere of on-line certification and unruly animals being brought aboard, it seems that a national and standardized system of certification would be beneficial for all involved.
