Pet cargo travel generates more anxiety among pet owners than almost any other part of the relocation process. A single incident story travels fast online. Millions of uneventful arrivals do not. The result is a public perception of cargo as inherently dangerous that does not match what the data actually shows. Here is a straightforward look at the evidence, what causes the incidents that do occur, and what separates a well-run cargo program from a poor one.
The US Department of Transportation requires airlines to report every incident involving the death, injury, or loss of an animal during air transport. These reports are published monthly and are publicly available at transportation.gov.
For the full calendar year 2024, US carriers reported 13 total incidents across all animals transported: 10 deaths, 3 injuries, and zero lost animals. Between 2015 and 2020, carriers reported 197 incidents out of more than 2.7 million animals transported — an incident rate of roughly 0.007%.
These numbers do not mean cargo is risk-free. But they do not support the narrative that cargo is a death sentence either. The fear and the data are badly misaligned, largely because high-profile incidents get extensive media coverage while routine safe arrivals do not.
This is the part that rarely gets reported. When you look at the actual causes behind documented incidents, airline negligence is far from the dominant factor. The most common contributors are:
A large share of in-flight deaths involve animals with underlying conditions that were not identified before travel. Heart disease, cancer, diabetes, obesity, respiratory conditions, and renal disease all appear repeatedly in incident reports. The stress of travel — separation, unfamiliar handling, noise, confinement — can trigger or accelerate a condition that was already present. A vet health certificate issued days before travel confirms fitness to fly at that moment; it does not guarantee that a hidden condition will not surface under stress. This is why a thorough pre-travel vet exam matters, and why honest disclosure of your pet's health history to both your vet and your transport coordinator is essential.
Flat-faced dogs and cats: bulldogs, pugs, French bulldogs, Boston terriers, Persian cats, and similar breeds carry elevated risk in cargo. Their compressed airways make breathing harder under normal conditions. Add the stress of travel, changes in temperature, and reduced air circulation inside a crate, and the risk increases significantly. Approximately half of documented dog deaths in air transport involve brachycephalic breeds. Most reputable cargo programs have specific restrictions or additional requirements for these breeds, and for the most severely affected animals, cargo is not appropriate at all. IPATA has developed a Brachycephalic Fit-to-Fly Assessment that veterinarians can use to evaluate whether a specific dog is suitable for cargo travel.
This one is counterintuitive but well documented. Sedating a pet before a flight feels like the humane thing to do. It is actually one of the most common contributing factors in transport deaths. Research presented to USDA and airline officials found that oversedation accounted for nearly half of animal deaths during airline transport. The reason: sedatives suppress respiratory and cardiovascular function. Altitude and pressure changes compound that effect. A sedated animal also cannot brace itself when the crate is moved, increasing injury risk. The American Veterinary Medical Association advises against sedation before air travel for these reasons. Neither IATA Live Animal Regulations nor responsible pet transport programs recommend it. If your pet has travel anxiety, discuss non-sedating anxiety management with your vet well before travel day.
Not all airlines handle live animals the same way. Incidents are not evenly distributed across carriers. Airlines without dedicated live animal programs, trained handlers, climate-controlled ground vehicles, and last-on-first-off policies expose pets to significantly more risk than those with robust programs. Similarly, a pet that has never been in a crate before travel day is a pet entering one of the most stressful experiences of its life completely unprepared.
There are two ways a pet can travel in the cargo hold: as excess baggage attached to an owner's ticket, or as manifest cargo booked independently through the airline's cargo division. These are not equivalent.
Manifest cargo books the pet as a separate shipment with its own tracking and handling chain. The routing can be optimized for the animal rather than matched to the owner's itinerary. If you need to rebook your own travel, your pet's movement is not automatically disrupted. Manifest cargo programs at dedicated pet-safe airlines also come with stronger live animal handling standards than excess baggage handling, which is managed through the passenger terminal rather than the cargo facility.
PetRelocation books all pets as manifest cargo on airlines with established live animal programs. Airline selection for each move is based on the specific route, the pet's size and breed, and the carrier's handling program for that routing.
When evaluating whether an airline is appropriate for your pet, the meaningful indicators are operational, not marketing:
For small pets that qualify, cabin travel is a legitimate option and keeps the animal in sight. The practical limitations are significant: the pet and carrier must fit under the seat, many international routes restrict or prohibit cabin pets regardless of size, and the number of cabin pets per flight is capped.
Cabin is not automatically the safer or less stressful option. The noise, movement, and proximity to strangers in a cabin environment can be more disorienting for many pets than the quieter, darker cargo hold. "In sight" is reassuring for the owner; it does not necessarily mean less stress for the animal. For larger pets and for most international moves, cargo is not a compromise — it is the standard, and it has been used successfully for decades.
The owner's preparation has a measurable impact on outcome. The most important steps:
