Does Volaris Allow Pets? Pets are really allowed on board Volaris flights. With some limitations and additional costs, Volaris offers a pet policy that permits travellers to bring small dogs and cats on board. A carrier that fits under the passenger's seat in front and has been approved by the airline must be used to transport the pet. The size and weight of the pet carrier must adhere to particular rules as well. It's crucial to keep in mind that Volaris has a limited number of pet carriers available in the cabin; therefore, it's advised to get in touch with the airline beforehand and book space for your pet.
