(Hedgehogs, ferrets, insects, rodents, snakes, spiders, sugar gliders, reptiles, amphibians, goats, animals improperly cleaned and/or with a foul odor and animals with tusks, horns or hooves are also not permitted on Delta as trained service or support animals.)
So we asked Delta about its peacock policy.
"We reserve the right to review each case," according to Delta spokeswoman Ashton Kang. "The list on Delta.com is intended to provide examples of exotic or unusual animals but is not considered to be a complete and exclusive list."
"Peacocks would fall under the definition of exotic or unusual animals as per 14 CFR 382.117," she added.
That federal regulation notes that airlines "are never required to accommodate certain unusual service animals (e.g.,snakes, other reptiles, ferrets, rodents, and spiders) as service animals in the cabin."
It continues: "With respect to all other animals, including unusual or exotic animals that are presented as service animals (e.g., miniature horses, pigs, monkeys), as a carrier you must determine whether any factors preclude their traveling in the cabin as service animals (e.g., whether the animal is too large or heavy to be accommodated in the cabin, whether the animal would pose a direct threat to the health or safety of others, whether it would cause a significant disruption of cabin service, whether it would be prohibited from entering a foreign country that is the flight's destination). If no such factors preclude the animal from traveling in the cabin, you must permit it to do so."
The federal regulation also stipulates that whenever airlines decide not to accept an animal as a service animal, "you must explain the reason for your decision to the passenger and document it in writing. A copy of the explanation must be provided to the passenger either at the airport, or within 10 calendar days of the incident."
