Pets can only board after presenting certain documents and certificates. For domestic flights, the following are required:

• Vaccination record with proof of polyvalent and rabies vaccinations administered more than 30 days ago and less than a year ago;
• Health certificate issued by a veterinarian within 10 days of travel, confirming that the pet is healthy and fit for travel.

Guide dogs are allowed to travel for free, on the floor of the aircraft cabin, next to their owner, under the owner's control, wearing a harness, and exempt from wearing a muzzle. The guide dog must be positioned in such a way that it does not block the aircraft aisle. Additionally, the owner must comply with the national health authorities' requirements and the destination country's regulations when applicable. The owner must present documents proving the animal’s training and identification, as well as provide the necessary food.

To transport animals from the Brazilian fauna, a Guide for Animal Transit (GTA) issued by a veterinarian authorized by the Ministry of Agriculture, Livestock, and Environment (MAPA) or by the relevant state health authority is required. In the case of these species, it is also necessary to prove that the animal was acquired legally by presenting the purchase invoice from a breeder or a licensed wildlife trader authorized by the competent environmental authority. If this document is unavailable, a transportation license issued by the competent environmental authority must be presented.

For traveling with exotic wild animals, a Guide for Animal Transit (GTA) issued by a veterinarian authorized by MAPA or the state health authority is required, along with authorization from IBAMA (Brazilian Institute of Environment and Renewable Natural Resources). The legality of the animal's acquisition must be proven by presenting the purchase invoice from an authorized breeder or wildlife trader. If the purchase invoice is not available, a transport license from the competent environmental authority must be provided.
