Your ears pop on a plane because the air pressure inside your middle ear and the air pressure in the cabin are temporarily out of balance. A small tube in each ear normally keeps these pressures matched, but rapid altitude changes during takeoff and landing can outpace the tube’s ability to adjust. That mismatch pushes or pulls on your eardrum, creating the familiar sensation of fullness, muffled hearing, and the satisfying “pop” when pressure finally equalizes.
How Your Ears Regulate Pressure
Each of your ears has a narrow channel called the Eustachian tube that connects the middle ear to the back of your nose and throat. Every time you swallow or yawn, this tube briefly opens to let a tiny puff of air in or out, keeping the pressure on both sides of your eardrum equal. You don’t notice it happening because the pressure differences in daily life are small and your body handles them automatically.
The Eustachian tube also drains mucus from the middle ear, which is why anything that causes swelling or congestion in the nose and throat can interfere with its ability to open. When the tube can’t do its job, air gets trapped in the middle ear, and pressure builds up against the eardrum.
What Happens During Takeoff and Landing
As a plane climbs, cabin pressure drops. The air already sealed inside your middle ear is now at a higher pressure than the air surrounding your eardrum, so it expands and pushes the eardrum slightly outward. Most people handle ascent fairly easily because the expanding air can force the Eustachian tube open on its own, releasing the excess pressure with a pop.
Descent is the harder part. As the plane drops altitude, cabin pressure rises, but the air in your middle ear is still at the lower pressure from cruising altitude. Now the higher-pressure cabin air pushes the eardrum inward, and the Eustachian tube doesn’t open as easily in this direction. You need to actively equalize by swallowing, yawning, or using a deliberate technique. This is why most ear pain happens during landing rather than takeoff.
The basic physics behind this follows a simple principle: when outside pressure drops, a trapped pocket of gas expands, and when outside pressure rises, it compresses. Your middle ear is essentially a small sealed chamber, and the Eustachian tube is its only vent.
Who Gets Hit Hardest
About 5% of adult passengers and 25% of children experience noticeable ear pain during flights. Children are far more vulnerable because their Eustachian tubes are shorter, narrower, and more horizontal than an adult’s, making it harder for air and fluid to move through. Babies and toddlers can’t deliberately equalize pressure, which is why they so often cry during descent.
Flying with a cold, sinus infection, or allergies significantly raises your risk. Swollen tissues and mucus can partially or fully block the Eustachian tube, preventing it from opening when you swallow. If you’ve ever flown while congested, you’ve probably felt the difference: instead of a mild pop, you may have experienced sharp pain that lasted well after landing. The same applies to anyone with chronic nasal congestion or a history of ear infections.
Techniques That Help Equalize Pressure
The simplest approach is to swallow frequently during ascent and descent. Chewing gum, sucking on hard candy, or sipping water all trigger the swallowing reflex and briefly open the Eustachian tube. For babies, nursing or sucking on a bottle or pacifier during descent serves the same purpose.
A more deliberate method is to pinch your nostrils shut, close your mouth, and gently blow as if trying to exhale through your nose. This forces air up through the Eustachian tubes and into the middle ear. It works well for many people, though research shows it’s not foolproof. In one study of ears with normal middle ear pressure, about 46% successfully equalized using this technique, while roughly 31% of participants couldn’t generate enough pressure to make it work at all. If gentle blowing doesn’t produce a pop, don’t force it, as blowing too hard can cause damage.
Another option is the combination approach: pinch your nose and swallow at the same time. This uses the muscles that actively open the Eustachian tube rather than relying on passive air pressure alone, and some people find it more reliable than blowing.
Pressure-Regulating Earplugs
Filtered earplugs designed to slow the rate of pressure change in the ear canal are available at most pharmacies. They don’t block the pressure change entirely but delay it by about 7 minutes, giving your Eustachian tubes more time to catch up. In pressure chamber testing, people wearing these earplugs reported significantly less discomfort compared to unprotected ears, even though the earplugs didn’t actually improve how well the Eustachian tube functioned. They essentially buy you time, which can be enough to make the difference between pain and a mild pop.
When Ear Pressure Becomes Barotrauma
If the pressure difference becomes large enough, the eardrum can stretch or sustain real injury. This is called ear barotrauma, and the typical symptoms include ear pain, a feeling of fullness or stuffiness, dizziness, and slight hearing loss. In most cases, the discomfort resolves within a few hours as pressure gradually equalizes on its own.
More severe cases can cause visible changes to the eardrum. A doctor examining the ear may see the eardrum bulging outward or pulled inward, and in serious cases, there can be blood or bruising behind it. Nosebleeds are another sign of significant pressure injury. These more intense episodes are uncommon but are more likely if you fly with heavy congestion or if you weren’t able to equalize at all during a rapid descent.
Permanent complications from airplane ear are rare. They can include hearing loss that doesn’t recover, chronic ringing in the ears (tinnitus), or ongoing dizziness. These outcomes are associated with severe or repeated barotrauma, particularly when there’s damage to the structures of the inner ear. If your ear pain doesn’t fade within a few hours of landing, or if you notice drainage, bleeding from the ear, or a sudden drop in hearing, those are signs of something beyond routine pressure discomfort.
Preventing Problems Before Your Flight
If you’re congested, using a decongestant nasal spray about 30 minutes before descent can shrink swollen tissue enough to let the Eustachian tubes open. Starting to equalize early and often during descent, rather than waiting until your ears feel blocked, makes a noticeable difference. Once the eardrum is already being pushed inward by high pressure, the Eustachian tube becomes harder to open, creating a cycle that’s tougher to break.
Staying awake during landing is also worth the effort. You don’t swallow as frequently while sleeping, so pressure can build unchecked. If you tend to doze off, ask a seatmate to wake you before the plane begins its descent, which is typically announced by the flight crew about 20 to 30 minutes before landing.
