Aircraft vs. Car -- The Honest Accident Statistics

Few topics provoke more emotional debate than the question of whether flying or driving is safer. Most people have an instinctive fear of flying that is entirely disproportionate to the actual risk. At the same time, these very people get into their cars without a second thought -- even though the statistics speak an unmistakable language. This article lays out the numbers, explains the different comparison methods, and shows why the perception of risk diverges so dramatically from reality.

The Fundamental Question: How Do You Compare?

Comparing aviation safety with road safety is more complicated than it first appears. The result depends critically on which reference metric is chosen. There are three common methods:

• Fatalities per billion passenger-kilometers -- compares risk relative to distance traveled.
• Fatalities per billion journeys -- compares risk per individual trip or flight.
• Fatalities per billion passenger-hours -- compares risk relative to time spent in the mode of transport.

Each of these methods produces a different picture -- and each has its merits and blind spots.

Method 1: Fatalities per Billion Passenger-Kilometers

This is the most widely used comparison method among experts because it accounts for the different distances traveled by different modes of transport.

The numbers are clear: per kilometer traveled, commercial aviation is by far the safest mode of transport. Driving a car is 44 times more dangerous per kilometer. This figure alone should be enough to put the fear of flying into perspective.

Method 2: Fatalities per Billion Journeys

This method compares risk per individual trip or flight, regardless of the distance traveled.

Using this comparison method, aviation appears to fare worse -- at first glance. But this comparison is fundamentally misleading, and here is why: an average "journey" by car is 15 kilometers long (the trip to the supermarket, to work, to daycare). An average "flight" is over 1,500 kilometers long. This amounts to comparing apples with oranges -- a drive to the bakery versus a flight from London to Madrid.

If the car journey were extended to the same distance as the average flight, the risk per "journey" by car would be dramatically higher than by aircraft. The "per journey" comparison is nevertheless occasionally cited by proponents of fear of flying -- though without providing the crucial context of the vastly different travel distances.

Method 3: Fatalities per Billion Passenger-Hours

Using this method as well, flying is significantly safer: driving a car is 4 times more dangerous per hour spent in the vehicle. This factor is smaller than in the per-kilometer comparison because an aircraft is considerably faster than a car and therefore covers a much greater distance in the same amount of time.

The Absolute Numbers: Worldwide Fatalities

The most striking perspective comes from the absolute numbers:

To put these numbers in perspective: Every day, nearly 3,700 people die in road traffic worldwide. That is the equivalent of ten crashes of fully loaded wide-body aircraft -- every single day. If road traffic received the same media attention as aviation, every news broadcast would have to begin with ten aircraft disasters.

The IATA Safety Report

The International Air Transport Association (IATA) publishes a comprehensive safety report annually. The data for the years 2019 to 2024 show a clear trend:

• 2019: 8 fatal accidents, 257 fatalities with 4.5 billion passengers.
• 2020-2021: Sharply reduced air traffic due to the pandemic, but the accident rate (per million flights) remained at historically low levels.
• 2022: 5 fatal accidents with a total of 158 fatalities.
• 2023: Despite air traffic returning to pre-pandemic levels, the accident rate remained extremely low.
• 2024: Preliminary data indicate one of the safest years in aviation history, with approximately 40 fatalities among over 4.5 billion passengers carried.

The accident rate per million flights in commercial aviation stands at approximately 0.18 -- meaning that statistically, a passenger would have to complete over 5 million flights before being involved in a fatal accident.

The Most Dangerous Part of Air Travel: The Drive to the Airport

It is one of the most frequently cited statistics in aviation, and it is true: The statistically most dangerous part of any air trip is the car ride to the airport. When a passenger drives 50 kilometers (30 miles) to the airport and then flies 2,000 kilometers (1,240 miles), the risk of dying during the car journey is significantly higher than the risk of dying during the flight.

The calculation is straightforward: 50 km of driving at a risk of 3.1 fatalities per billion passenger-kilometers yields a risk of 0.000000155. A 2,000 km flight at a risk of 0.07 fatalities per billion passenger-kilometers yields a risk of 0.00000000014. The car ride to the airport is therefore approximately 1,100 times more dangerous than the flight itself.

Why Risk Perception Is So Distorted

If flying is so much safer than driving, why do so many people have a fear of flying but hardly anyone has a "fear of driving"? The answer lies in the psychology of risk perception:

• Illusion of control: In a car, we feel we are in control of the situation -- we sit behind the wheel, we decide the speed and direction. In an aircraft, we surrender control entirely. Psychologically, we perceive risks that we cannot control as far more threatening.
• Availability heuristic: Aircraft crashes are spectacular, media-omnipresent events. A single plane crash dominates the news for days. Car accidents, on the other hand, are so commonplace that they appear as brief mentions at best. Since we judge the frequency of events by how easily we can recall them, we massively overestimate the risk of flying.
• Catastrophe heuristic: We fear events in which many people die simultaneously more than events in which individuals die -- even if the total number of victims is much higher. 300 deaths in a plane crash shock us more than 300 deaths on the roads over a single weekend.
• Naturalness: Driving feels "natural" -- we are on the ground, in a familiar environment. Flying, by contrast, defies our intuition: we are in a metal tube, 10 kilometers (35,000 feet) above the ground, with hundreds of strangers. This unnaturalness amplifies the unease.

Putting It in Perspective: Flying Compared to Other Activities

To put the risk of flying into even sharper perspective, here is a comparison with other everyday activities and their associated mortality risk:

Even an extreme frequent flyer who covers 200,000 kilometers per year by air (equivalent to roughly five circumnavigations of the Earth) has a lower mortality risk from flying than an average driver has from driving.

The Insurance Industry Knows

Insurance companies are experts in risk assessment -- their business model depends on evaluating risks correctly. And what do insurers say about flying?

• Life insurance: For regular passengers, there is no surcharge for air travel. Frequent flyers do not pay a higher premium. This would be unthinkable if flying represented a significant risk.
• Travel insurance: Premiums for air travel are minimal, reflecting the extremely low risk.
• Auto insurance: Premiums for car insurance, by contrast, are substantial -- a clear indication that insurers consider driving to be far riskier.

The insurance industry thus confirms what the statistics show: flying is one of the safest activities a person can undertake.

The Historical Trend: It Keeps Getting Safer

Particularly noteworthy is that the safety of commercial aviation is not plateauing but continues to improve steadily. In the 1970s, there were still several fatal accidents per million flights. In the 2020s, the rate stands at 0.18 per million flights -- an improvement by more than a factor of ten over five decades.

In road traffic, progress has been significantly slower. While ABS, airbags, ESC, and driver-assistance systems have improved safety, the number of road fatalities per billion passenger-kilometers has only decreased by approximately 30-40% over the last 20 years -- compared to over 80% reduction in aviation during the same period.

Conclusion: The Numbers Speak a Clear Language

Regardless of which comparison method is chosen, regardless of which time period is examined, regardless of which region of the world -- commercial aviation is safer than road traffic. This is not an opinion but a statistical fact confirmed equally by international organizations (ICAO, IATA, WHO), government agencies (EASA, FAA, NTSB, BFU), and the insurance industry.

The fear of flying is human and understandable -- but it is irrational. Anyone who feels uneasy on their next flight should remember: the most dangerous part of the journey is already behind them -- the car ride to the airport.

If driving were as safe as flying, there would be fewer than 30,000 road traffic fatalities per year worldwide instead of 1.35 million. Aviation has proven that extreme safety is achievable through systematic learning from mistakes, strict regulation, and a culture of continuous improvement. Road traffic can and should learn from this industry.
