Who Is at Risk of Ear Blockage During a Flight?

Ear blockage during flights can happen to almost anyone, especially during takeoff and landing when air pressure changes quickly.
However, some people are more likely to develop severe or prolonged ear blockage. This usually happens when the Eustachian tube cannot equalise pressure efficiently.
People at higher risk include those with:
A naturally narrow Eustachian tube
Allergies causing nasal swelling
Upper respiratory infections such as colds or sinusitis
Enlarged adenoids or tissue growth near the Eustachian tube opening – common in children
In these situations, the ear struggles to adjust to pressure changes during the flight, leading to ear pain, muffled hearing, or a blocked sensation.
Why Do Ears Hurt During Flights?
Ear pain during flights occurs because of rapid changes in air pressure inside the airplane cabin, especially during takeoff and landing.
When the pressure inside the middle ear does not match the pressure outside, a pressure difference develops across the eardrum. This prevents the eardrum from vibrating normally, causing a sensation of ear blockage or muffled hearing.
This condition is commonly known as airplane ear or ear barotrauma.
Ear Anatomy That Helps Balance Pressure
Understanding a small part of ear anatomy helps explain why this happens.
The eardrum (tympanic membrane) separates the outer ear from the middle ear.
Behind the eardrum lies the middle ear, which is an air-filled space containing tiny hearing bones that transmit sound to the inner ear.
For hearing to work properly, the air pressure on both sides of the eardrum must remain equal. When the pressure becomes unequal, the eardrum may get pulled inward or pushed outward, which interferes with its ability to vibrate.
This leads to:
Muffled hearing
A feeling of fullness in the ear
Pressure or discomfort
The Role of the Eustachian Tube
The body keeps ear pressure balanced using a small passage called the Eustachian tube.
This tube connects the middle ear to the nasopharynx, the area behind the nose and upper throat.
Its job is to allow air to move between the middle ear and the nose, keeping the pressure equal on both sides of the eardrum.
Normally, the tube opens briefly when we:
Swallow
Yawn
Chew
This is why swallowing, chewing gum, or yawning during flights often helps relieve ear pressure.
Why the Ear Feels “Blocked” During a Flight
When the Eustachian tube does not open properly, the pressure inside the middle ear cannot equalise quickly enough.
As a result, the eardrum cannot move normally.
This causes:
Muffled hearing
A feeling of pressure in the ear
The sensation that the ear is blocked or clogged
Interestingly, the ear is not physically blocked by anything.
The blocked sensation happens because the eardrum cannot vibrate normally due to the pressure difference across it. This causes a temporary partial hearing loss, which the brain interprets as a blocked ear.
Once the pressure equalises and the Eustachian tube opens, the eardrum returns to its normal position and hearing becomes clear again.
Conditions That Increase the Risk of Ear Blockage During Flights
Although mild ear discomfort is common during flights, certain conditions make it harder for the Eustachian tube to equalise pressure.
1. Naturally Narrow Eustachian Tube
Some people are born with a narrow Eustachian tube, which restricts airflow between the middle ear and the nose.
When pressure changes rapidly during a flight, the ear may struggle to equalise pressure, leading to:
Stronger ear pain
Prolonged ear blockage
Difficulty clearing the ear after landing
2. Allergies
Allergies can cause swelling of the lining of the nose, throat, and upper respiratory tract.
Since this lining also extends into the Eustachian tube, swelling can partially block the tube and prevent pressure equalisation.
Even mild allergy symptoms can make flying uncomfortable.
3. Upper Respiratory Infections
Conditions affecting the upper respiratory tract can significantly increase the risk of airplane ear.
These include:
Common cold
Sore throat
Laryngitis
These illnesses cause nasal congestion and inflammation, which can interfere with the normal function of the Eustachian tube.
As a result, ear pressure during flights may become more severe and last longer.
4. Enlarged Adenoids or Tissue Growth in the Nasopharynx
The opening of the Eustachian tube is located in the nasopharynx, the space behind the nose.
Any extra tissue growth in this area can block the opening of the tube.
One common cause is enlarged adenoids, which are frequently seen in children.
Enlarged adenoids can partially block the Eustachian tube opening, making it difficult for the ear to equalise pressure during flights.
When Should You Take Extra Precautions Before Flying?
If you fall into any of the above categories, it is better to take precautions before flying.
Simple steps such as encouraging swallowing, managing nasal congestion, and using nasal drops when advised by a doctor can help reduce the risk of ear blockage.
