Animal Transport by Air: Welfare Challenges in the Cargo Hold

Millions of animals are transported by air annually for various purposes. Conditions in aircraft cargo holds present unique welfare challenges that regulations incompletely address.

Key Facts

Animals transported by air include companion animals, zoo animals, livestock for breeding, and laboratory animals.
The IATA Live Animals Regulations set minimum standards for container size, ventilation, food, water, and handling.
Temperature extremes in cargo holds — both excessive heat and cold — are leading causes of air transport mortality.
Brachycephalic dog breeds face particular risks in air cargo due to their compromised respiratory function under stress.
Many airlines have banned brachycephalic breeds from cargo transport following significant mortality rates.
Companion animals transported in cabin (in-cabin pet allowance) experience significantly better welfare than cargo.
Long-haul flights impose extended confinement without water or food access despite IATA requirements for provision.
Wild animals transported for zoo collections face stress from capture, handling, container confinement, and unfamiliar environments.

Welfare Considerations

Air transport of animals causes acute stress through multiple mechanisms: confinement, vibration, noise, temperature variation, separation from social companions, and inability to engage in normal behaviour. The cargo hold environment is particularly challenging: animals cannot be monitored, cannot be assisted if distressed, and may experience temperature extremes if climate control fails. Companion animal deaths in air cargo, while statistically rare, are disproportionately concentrated in brachycephalic breeds and summer travel. The welfare case for in-cabin transport where possible, for robust IATA compliance monitoring, and for restrictions on high-risk species and conditions is strong. Breeding decisions that produce dogs with respiratory compromise are directly relevant to air transport welfare.

What You Can Do

Transport companion animals in-cabin rather than cargo wherever possible.
Avoid air travel with brachycephalic breeds given their elevated risk of respiratory crisis under stress.
Choose airlines with strong live animal transport policies and compliance records.
Check IATA container requirements carefully and use approved containers for any air transport.
Advocate for stronger regulatory requirements for live animal air transport including temperature monitoring.
Support alternatives to wild animal air transport for zoo collections, such as captive breeding at destination.
