No more other animal pals such as pigs, ferrets, hamsters or even snuggly ponies can accompany panicky passengers aboard American Airline planes.

There is also required a veterinary health form that lists the pet's vaccination and other health details. Also, Fido and Fluffy must be at least 4 months old. It’s expected that other airlines will be imposing similar restrictions. So, if you medically or emotionally expect to fly with your pet, be sure to check with the airline on all rules that apply.
