Your ears pop on a plane because the air pressure inside your middle ear and the air pressure in the cabin are changing at different speeds. Your body has a built-in system for keeping those pressures equal, but rapid altitude changes can outpace it, creating a temporary imbalance that stretches your eardrum and produces that familiar popping, fullness, or mild pain.
How Your Ears Regulate Pressure
Each of your ears has a narrow tube made of bone and cartilage called the eustachian tube. It runs from your middle ear to the back of your nose and throat. Most of the time, this tube stays closed, which protects your middle ear from bacteria and viruses. When you swallow or yawn, the tube briefly opens and lets a tiny amount of air pass through so the pressure on both sides of your eardrum stays balanced.
This system works well on the ground, where atmospheric pressure changes gradually. On a plane, pressure shifts happen much faster than your eustachian tubes can keep up with, and the result is a pressure mismatch across your eardrum. That mismatch is what you feel as fullness, muffled hearing, or a distinct pop when the tube finally opens and air rushes through to equalize.
What Happens During Takeoff and Landing
Commercial aircraft cabins are pressurized, but not to sea-level pressure. At cruising altitude, the cabin is typically pressurized to the equivalent of roughly 6,000 to 8,000 feet above sea level. That means the air pressure around you drops as the plane climbs and rises again as it descends.
During ascent, the air in your middle ear is at a higher pressure than the cabin. That extra pressure pushes your eardrum slightly outward. In most people, the eustachian tube lets the excess air escape on its own without much effort, which is why takeoff tends to feel less uncomfortable.
Descent is the trickier phase. As the plane comes down, cabin pressure increases, but the air in your middle ear is now at a lower pressure than the cabin. Your eardrum gets pushed inward, and the eustachian tube doesn’t open as easily in this direction. Air needs to actively move into the middle ear, which requires you to swallow, yawn, or use a deliberate technique to coax the tube open. This is why most ear discomfort happens during landing.
Why Some People Struggle More
Anything that narrows or inflames the eustachian tube makes it harder for air to pass through. Allergies, the common cold, the flu, sinus infections, and even chronic acid reflux can all cause enough swelling to partially block the tube. If you’ve ever flown with a head cold, you’ve probably noticed the difference: instead of a quick pop, you get persistent pressure, pain, or ears that stay clogged for hours after landing.
Children are especially prone to ear trouble on flights. Their eustachian tubes are shorter, narrower, and more horizontal than an adult’s, which makes the movement of air and fluid more difficult. Babies and toddlers can’t deliberately pop their ears, so they often cry during descent, not because of fear, but because of genuine ear pain.
How to Pop Your Ears
Several techniques can help force the eustachian tube open. None of them is dramatically more effective than another in studies, so pick whichever works best for you.
- Swallowing or chewing gum: The muscles involved in swallowing naturally tug the eustachian tube open. Chewing gum during descent keeps you swallowing frequently. For babies, a bottle or pacifier serves the same purpose.
- Yawning: A wide yawn activates the same muscles more forcefully. Even a fake yawn can do the trick.
- The Valsalva maneuver: Pinch your nostrils shut, close your mouth, and gently blow as if trying to push air out of your nose. This forces air up through the eustachian tubes. Don’t blow hard, as too much force can cause damage.
- The Toynbee maneuver: Pinch your nostrils shut and swallow at the same time. The swallowing motion pulls the tube open while your pinched nose directs the pressure change toward the middle ear. Some people find this gentler and easier than the Valsalva.
The key is to start early. Begin swallowing or using these techniques as soon as the plane starts its descent, not once your ears already hurt. Once the eardrum is pressed inward and the tissue around the tube is swollen from the pressure difference, it becomes much harder to equalize.
When Ear Pressure Becomes Ear Barotrauma
The medical term for pressure-related ear injury is barotrauma. Mild barotrauma is extremely common during flights and resolves on its own within minutes to hours. Symptoms include ear discomfort or pain, a feeling of fullness or stuffiness, slight hearing loss, and occasionally dizziness.
In more severe cases, especially if the pressure difference is large or you’re flying with significant congestion, the eardrum can actually rupture. Signs of a ruptured eardrum include sudden sharp pain that may fade quickly, fluid or blood draining from the ear, noticeable hearing loss, ringing in the ear, and a spinning sensation with nausea. Most ruptured eardrums heal on their own within three to six months, but complications can develop if healing doesn’t progress normally.
Reducing Discomfort Before You Fly
If you’re congested, a nasal decongestant spray used about 30 minutes before descent can temporarily shrink swollen tissue around the eustachian tubes. Oral decongestants taken an hour or so before the flight work similarly. For people with allergies, taking your usual antihistamine before flying helps prevent the inflammation that makes equalization difficult.
Filtered earplugs designed for air travel slow the rate of pressure change reaching your eardrum, giving your eustachian tubes more time to adjust. They won’t eliminate the sensation entirely, but they can reduce the intensity, especially during rapid descents. Staying awake during descent also matters. Your swallowing rate drops significantly when you sleep, which means your ears can fall far behind on pressure equalization before you wake up to a painful blockage.
