Answer:
Although some airlines will allow you to fly rabbits and other pets in the cargo hold, this can be very dangerous and stressful for the animal -- many people advise against it. More and more airlines are allowing pets to travel with their owners in the passenger sections of the plane, but most of these airlines only allow cats and dogs. Even flying in the passenger section of a plane can be dangerous for pets, so anyone thinking of taking their rabbit on the plane should spend a lot of time weighing the pros and cons, considering other options, talking to rabbit authorities (like vets, and experienced rabbit owners), and planning ways to lessen each and every risk.
