When it comes to transportation, there's a hidden danger in choosing what feels safer. A commercial airplane crash can change how people behave long after the immediate tragedy. News outlets replay the images, people affected share their harrowing stories, and an extraordinarily rare event becomes easy to imagine. Some travelers cancel trips; others drive to their destination instead. These choices may feel cautious. Statistically, the alternatives people switch to may come with greater risk. Commercial airline crashes command attention because they are rare, catastrophic, and beyond a passenger's control. But the choice to avoid flying does not eliminate risk. A new report from a research team at Embry-Riddle Aeronautical University outlines that skipping a flight and opting to drive instead is typically much riskier, even if it doesn't feel like it. This is due in part to how people perceive risk—vivid, rare events often seem more dangerous than common, everyday hazards, even if the latter are more likely to cause harm. The study focused on commercial Part 121 airlines operating in the U.S. and analyzed data from 2016 through 2025. Part 121 carriers generally include large U.S. airlines and regional carriers that operate scheduled passenger service. Because fatal accidents are so rare, data from a single year would not have provided a stable risk estimate. Across several measures of risk exposure, including distance traveled, individual boardings, hours spent traveling, annual risk, and lifetime odds, the data consistently shows that U.S. commercial aviation is exceptionally safe. For the same distance traveled, the fatality risk was estimated to be about 626 times higher in a passenger car or truck than on a commercial airline. The risk associated with motorcycle travel was more than 22,000 times higher than commercial airline travel. Even highway bus travel, itself a relatively safe option, carried about nine times the risk of commercial airline travel over the same distance. These numbers underscore the significant difference in safety between air travel and other forms of transportation. The aftermath of the Sept. 11, 2001, terrorist attacks provided a powerful example of how behavior can shift risk from one setting to another. Air travel declined sharply after the 9/11 attacks. Subsequently, researchers were able to investigate whether fear of flying led to additional deaths on the road. Psychologist Gerd Gigerenzer analyzed traffic patterns and estimated 353 excess road deaths nationwide. Later studies suggested the number could be as high as 1,018 additional road fatalities in the months following the attacks. This shift in behavior highlights how avoiding a visible, low-probability risk can increase exposure to more common but less visible dangers. One reason discussions about risk become confusing is that there is no single way to measure it. The answer to the question “Is it safe?” depends on what you measure. How much risk does a person face for each mile traveled? What is the risk of one trip? How much risk accumulates during one hour of travel? What is the chance of dying from this cause in a year or over a lifetime? These are legitimate questions, but to make a valid comparison, you need to look at the same measure of risk for both types of transportation. Time matters too. In estimates, an hour in a passenger car or truck carried about 74 times the fatality risk of an hour aboard a commercial aircraft. Driving gives people a steering wheel, a brake pedal, and the belief that their skill can protect them. Flying asks passengers to place control in the hands of pilots, airlines, regulators, air traffic controllers, and a complex technical system. Psychological research has linked a stronger sense of agency—feeling in control of one’s actions and outcomes—with greater risk-taking. That difference in perceived control helps explain why a rare aviation disaster can feel more threatening than routine road travel. Media attention also matters. A major airplane crash is treated as news of national or international importance. Road deaths occur across many locations and at different times, so the public does not see the cumulative toll. The emotional intensity of coverage does not mean journalists are wrong to cover crashes. It just means audiences need context alongside the images. Telling anxious travelers that flying is “safe” is rarely enough. Research on risk perception shows that people do not judge danger through statistics alone. Fear and vivid images also shape how risky an event feels. But providing more context about the risks from other forms of transportation can still help. Effective communication about risk does not minimize tragedy or dismiss the real fear people may feel. But it can help people understand that when millions of travelers shift from one type of transportation to another, the risk moves with them. For travelers, the practical question is not whether an option has zero risk. No option does. The question is whether a choice reduces their total exposure to risk or merely replaces a frightening, highly visible risk with a greater one that feels routine. To put the rarity of fatal airline events into perspective, an average of 2.48 million travelers passed through TSA screening each day in 2025. Modern commercial aviation in the United States has achieved a safety record that is difficult to grasp precisely because fatal events are so unusual. When fear leads people away from that system, the safest-feeling decision may not be the safest decision at all.
