Are you considering bringing an animal other than your dog or cat on your future trip? The frontier airlines pet policy states that domestic dogs, cats, rabbits, farm animals, hamsters, or small house birds may be transported on flights inside the United States for one-way travel fees. This is larger than the pet policy of many other airlines. Only domestic cats and dogs are permitted to enter or exit other nations. For the safety of your pet, the shipping container must always be used. It is not allowed to check pets as luggage.
