Psychology explains why some people are terrified before flying, and it may have less to do with the plane itself

In a 2024 study, researcher Matthew K. Laker of Charles University in Prague and colleagues found that people with higher levels of psychological stress were significantly more likely to report a fear of flying, also known as aerophobia. Their findings were published in the journal Neuropsychiatric Disease and Treatment.
What is flight phobia?
Aviophobia is an intense fear of flying that falls under a specific phobia category in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Although many travelers feel nervous before a flight, aviation phobia goes much further. People with this condition may experience extreme anxiety when seeing a plane, waiting to board, or even listening to an announcement about landing.
Researchers note that some estimates suggest that up to 40 percent of people in industrialized countries experience some degree of fear of flying.
Symptoms may include:
- rapid heartbeat
- increased blood pressure
- hyperventilation
- stomach upset
- panic attacks
- Fear of losing control or dying during flight
In many cases, the fear becomes so severe that people avoid flying altogether, affecting holidays, family relationships, and even career opportunities.
Research links stress to fear of flying
Researchers surveyed 61 adults ages 20 to 35 in Illinois who had traveled for business in the past two years.
Participants completed several validated psychological surveys measuring:
- fear of flying
- Traumatic stress symptoms
- burnout
- Stress-related neurological symptoms
- emotional exhaustion
The results showed a clear pattern.
People who reported higher levels of stress also reported significantly greater fear of flying. The strongest relationship was found between traumatic stress symptoms and flight anxiety.
Researchers also found that greater fear of flying was associated with higher burnout scores and more stress-related neurological symptoms.
Women surveyed also reported higher levels of flight anxiety than men.
Why stress can make flying scarier
According to researchers, chronic stress and traumatic experiences can cause the brain to become more sensitive to situations perceived as threatening. Instead of responding only to actual danger, the brain may begin to respond intensely to relatively safe situations, such as boarding an airplane.
The study suggests that this increased sensitivity may explain why some people experience overwhelming fear despite knowing that commercial aviation is statistically very safe.
Researchers also discuss the possibility that some stress-related neurological symptoms, sometimes described as “epileptic-like” symptoms due to increased activity in the temporal and limbic regions of the brain, may play a role in some individuals. However, they also state that these are not the same as epilepsy and that their study does not establish a direct causal relationship.
Fear of flying isn’t always about planes
Researchers note that the fear of flying often overlaps with other fears:
- fear of heights
- Claustrophobia
- fear of injury
- Fear of losing control
- fear of death
Because these fears can occur together, aviation phobia can be difficult to diagnose and treat.
The study has important limitations
The authors note that the findings should be interpreted with caution. The study included only 61 participants, relied entirely on self-reported surveys, and identified correlations rather than cause-and-effect relationships.
This means that the research does not prove that stress or burnout causes fear of flying. Other factors not measured in the study may also contribute.
For some travelers, pre-flight anxiety may have less to do with the plane and more to do with how previous stress, emotional exhaustion, and traumatic experiences shape the brain’s response to perceived danger.
