SPCA acknowledges that air transportation is stressful for animals, in particular the loading and unloading components, and every step should be taken to reduce the stress involved. Where animals are air transported, SPCA recommends that steps are taken to minimise welfare harms such as examination by a veterinarian prior to transportation, choosing an appropriately sized crates, crate training prior to transportation and choosing a direct flight where possible.

SPCA supports airlines that adopt policies which allow appropriate companion animals to travel in the cabin on domestic flights.

Where an airline does permit animals in the cabin, animals should be contained in an appropriate, well-ventilated pet carrier under the seat. Animals should never be placed in an overhead bin.

SPCA opposes air transportation of brachycephalic animals due to the increased risk of welfare harms during air travel.

Air transportation of brachycephalic (short-muzzled) animals is complicated by their increased risk of respiratory problems and heat stress, when compared with animals of normal muzzle length. Abnormal brachycephalic anatomy often results in difficulties in breathing and thermoregulation. When this is coupled with additional stressors (such as transportation, stress, exercise, high temperatures, or inadequate ventilation), brachycephalic animals may be unable to adequately compensate, and this can result in over-heating, respiratory distress, collapse and, in some cases, death. As air transportation presents a significant risk to brachycephalic animals, many airlines have prohibited the carriage of these breeds. SPCA recommends owners choose methods of transport in which direct supervision of the animal throughout the transport process is possible.
