    "description": "Pet owners tend to worry a lot about putting a dog or cat into an aircraft cargo hold, and a handful of high-profile incidents (the 2018 United French bulldog puppy death, the annual \"worst airline for pets\" headlines) anchor that fear. We have not found a standalone survey isolating \"fear of your pet dying in air cargo\", so perceived risk is marked as editorial intuition. The rough sense most worried owners carry — that the risk is real but not everyday — is actually close to the numbers. What people usually get wrong is not the average rate, it's the enormous gap between breeds.\n",

Headline figure uses the 2024 annual ATCR numbers: 10 animal deaths across 161,335 animals transported by reporting US carriers, for a per-flight death rate of roughly 1 in 16,000. Averaging the 2021 (7 deaths / ~256,000 transported), 2023 (8 / 124,593), and 2024 (10 / 161,335) years gives approximately 25 deaths across ~542,000 pet-flights, or about 1 in 21,700 — rounded to 1 in 20,000 as the headline point estimate. The scope is declared activity_specific_lifetime because this is per-pet-per-flight risk for a specific activity, not a general-population lifetime risk, and it is not directly comparable to the US-adult lifetime figures on most other Likelier pages. Incident reports cover death, serious injury, and loss; the 1 in 20,000 figure counts deaths only, not injuries or lost animals, which roughly double the total incident rate to around 1 in 12,000 per pet-flight.\n",

      "calculation_notes": "Airlines that transport animals in the US are required by 14 CFR Part 235 to report every death, injury, or loss of an animal during air transport to the DOT, which publishes the tallies in the monthly Air Travel Consumer Report. Dividing the 10 reported deaths by the 161,335 animals transported in 2024 gives a per-flight death rate of 1 / 16,134 ≈ 0.0000620, or roughly 6 per 100,000 pet-flights. Including injuries and lost animals as \"incidents\" raises the combined figure to 13 / 161,335 = 1 in 12,410 per pet-flight. The DOT's headline \"0.81 incidents per 10,000\" phrasing matches this 1-in-12,000 combined-incident rate, not the death-only rate. The three-year average across 2021 (7/~256,000), 2023 (8/124,593) and 2024 (10/161,335) gives 25 deaths across roughly 542,000 pet-flights, or 1 in 21,700 — the basis for the 1 in 20,000 headline.\n",
      "independence_note": "DOT is the upstream source for US airline pet incident data; essentially every other secondary report (AVMA, Time, PetFlight, AWI) depends on the same Part 235 filings, so these are not independent measurements, just different presentations of the same regulatory dataset.\n"

      "calculation_notes": "AVMA summarised a DOT-data review showing that brachycephalic (short-snouted) breeds accounted for roughly half of all dog deaths on US airline flights in 2005-2010, despite being a much smaller fraction of the total pet population transported. This is the main evidence for the ~10x breed multiplier used in the personal factor table: if English bulldogs alone contributed 25/122 ≈ 20 percent of all dog deaths at a far lower share of total transported pets, their per-flight death rate is roughly an order of magnitude above the all-breed average. Several US airlines (Delta, United, American) subsequently banned many brachycephalic breeds as checked cargo based partly on this data.\n",
      "independence_note": "AVMA's summary is built on the same underlying DOT Part 235 animal incident reports as the first source, so the two citations share an upstream dataset. They are used here as complementary rather than independent: the DOT report is the authoritative headline rate, and AVMA provides the breed-level breakdown that the raw DOT tables do not publish in a digested form.\n"

      "calculation_notes": "The Bulfon et al. owner-reported survey is the most recent peer-reviewed study of how companion dogs tolerate air travel. Used here as a qualitative cross-check on two points: (a) the headline rate of fatal or serious adverse events is small but nonzero even in a self-selected sample of travel-willing owners, and (b) the distribution of stress responses is highly skewed — most dogs recover quickly, a small minority suffer substantial post-flight effects, and fatalities concentrate in cargo hold placement. The study is not powered to compute a per-flight mortality rate directly (n=663 dogs, 2 deaths is not a stable denominator), but it corroborates the DOT pattern that deaths, when they occur, are overwhelmingly in cargo hold rather than cabin travel.\n",
      "independence_note": "Bulfon et al. collected an independent owner-reported sample rather than DOT Part 235 filings, so this source is methodologically independent of the first two. It measures a partially overlapping population (pet dogs on commercial flights, mostly European and Australasian carriers) but uses a separate data-collection pipeline.\n"

It does not include foreign carriers, cargo-only airlines, ground-transport pet shipping, or shipments that were declined at check-in for heat embargo or health reasons (which remove higher-risk animals from the denominator before they ever fly). The dataset also does not separate \"died during the flight\" from \"euthanized after arrival due to a flight-related condition\" from \"died of a pre-existing condition that happened to surface during transit\", which are treated as a single reporting category. Finally, the headline rate has drifted downward over the past decade because several US airlines stopped accepting many brachycephalic breeds as cargo, mechanically removing most of the historical fatalities from the system; the residual all-breed rate describes the risk profile of what the airlines still transport, not what they used to transport. Readers comparing this figure to pre-2018 reporting should expect the older numbers to be materially higher.\n",
