Flying is one of the most commonly cited phobias. In the Chapman Survey of American Fears, roughly one in four US adults reports being afraid or very afraid of flying in an airplane. That framing collapses "dislike turbulence" and "avoid all flying" into one bucket, but the headline is robust: flying feels much riskier than it is.

Assumes ~4 commercial boardings per year for a typical US adult (BTS data for adults who fly, including connecting segments), 59 years of remaining adult life, constant risk per boarding (conservative vs the long-term safety trend).

Excludes private aviation, which has a meaningfully higher per-hour fatality rate. Also excludes major single-event anomalies (e.g., conflict zones, single-carrier outliers) which can dominate short windows but not long averages.

Most fear of flying isn’t really about the probability — it’s about control, enclosure, and the vividness of the few disasters that do make the news. The numbers reflect the opposite picture: commercial aviation is one of the safest forms of transport ever built. Per Barnett’s analysis, the per-boarding fatality rate has roughly halved every decade since the late 1960s — about 39 times safer today than fifty years ago.
If you fly a couple of times a year for the rest of your adult life, your accumulated lifetime risk is roughly 1 in 58,000 — comparable to the lifetime odds of being killed by a hornet, wasp, or bee sting, and about 600× lower than the lifetime odds of dying in a car crash. For most readers, the rational concern is the drive to the airport, not the flight.
What the numbers don’t tell you: the distribution is not uniform. Private aviation, general aviation, and certain regional carriers in certain regions are all meaningfully riskier than the global scheduled-commercial average used here. If any of those describe your flying, the per-boarding number from Barnett’s MIT analysis is the wrong baseline for you.
Related tidbits
Dying in a car crash is roughly 560× more likely than dying in a plane crash over a US adult lifetime (~1 in 105 vs ~1 in 59,000). The fear of flying does not flip when people get in the car.
A US adult is about as likely to be struck and killed by lightning as to die in a plane crash, within a factor of 5 (~1 in 280,000 vs ~1 in 59,000). The two feel nothing alike.
Sedentary behavior accounts for ~9% of premature deaths globally. The odds of dying in a plane crash are about 1 in 11 million per flight. Your desk chair is statistically more dangerous than your seat on the plane.

Study: Flying keeps getting safer- Statistic
1 fatality per 13.7 million passenger boardings (2018-2022 commercial aviation)- Excerpt
“"The risk of a fatality from commercial air travel was 1 per every 13.7 million passenger boardings globally in the 2018-2022 period, a significant improvement from 1 per 7.9 million boardings in 2008-2017." ”

- Verification
- Excerpt independently re-fetched and confirmed word-for-word against the cited source during our grounding audit.
- Calculation
- Barnett's "death risk per boarding" is already the exact statistic we want as the native value. Normalized = 1 − (1 − p_flight)^(flights_per_year × years) ≈ p_flight × flights × years for small p. Using ~4 boardings/year and 59 years: 4 × 59 / 13,700,000 ≈ 1 in 58,000 lifetime.
- Independence
- Barnett's MIT analysis pulls from IATA/ICAO commercial-aviation incident records plus passenger-boarding counts; overlaps with the NTSB accident database rather than being fully independent, though Barnett's per-boarding methodology is the distinctive analytical layer here.

- Calculation
- The NTSB research page provides downloadable accident statistics and an interactive dashboard covering 2005-2024. Part 121 air carrier operations (passenger-seat configuration >9 seats) have a well-documented record of extremely low fatal accident rates, consistent with Barnett's per-boarding figure. Used as a corroborating institutional source rather than the primary number.
- Independence
- NTSB and Barnett draw from overlapping aviation incident databases, so treat as partially dependent verification, not two fully independent estimates.

- Calculation
- NSC's Injury Facts "Odds of Dying" table lists 2024 lifetime odds of death from hornet, wasp, and bee stings at 1 in 42,626, derived from NCHS mortality data and Census Bureau life-expectancy figures. Used here only as an illustrative comparison point for this entry's lifetime figure of 1 in 58,000 — both are low-probability lifetime causes of death of a similar order of magnitude. Not part of the native/normalized calculation for this entry.
- Independence
- NSC's mortality-based lifetime-odds tables are methodologically independent of Barnett's per-boarding aviation analysis and the NTSB accident statistics cited above.
