Ear pain during a flight is caused by a pressure imbalance between the air inside your middle ear and the rapidly changing air pressure in the cabin. This imbalance stretches your eardrum inward or outward, triggering pain, fullness, and sometimes temporary hearing loss. The problem is most intense during descent, when cabin pressure rises faster than your body can adjust.
How Pressure Creates the Pain
Your middle ear is a small, air-filled space sealed off from the outside by your eardrum. It connects to the back of your throat through a narrow channel called the Eustachian tube. Under normal conditions, this tube opens briefly every time you swallow or yawn, letting air flow in or out to keep the pressure on both sides of the eardrum equal.
When a plane climbs after takeoff, cabin pressure drops. Air inside your middle ear expands and pushes outward through the Eustachian tube, which is relatively easy. During descent, the opposite happens: cabin pressure rises, and air needs to flow back into the middle ear to equalize. The Eustachian tube doesn’t open as readily in this direction, so higher-pressure air on the cabin side pushes your eardrum inward. That stretch is what you feel as pressure, stuffiness, or sharp pain. The faster the descent, the more dramatic the mismatch.
What It Feels Like
Mild cases produce a sensation of fullness or stuffiness, similar to being underwater. You might notice muffled hearing in one or both ears, along with general discomfort. Most people experience this level during a typical flight, and it resolves within minutes of landing.
More severe cases involve distinct pain, dizziness, moderate hearing loss, or even a nosebleed. If the pressure difference becomes extreme and the eardrum can’t stretch any further, it can rupture. This is uncommon on commercial flights but possible, especially if your Eustachian tubes are already compromised.
Why Some People Are More Affected
Anything that narrows or blocks the Eustachian tube makes equalization harder. The most common culprit is a cold. Swollen membranes in your nose can extend into the Eustachian tube and seal it off. Sinus infections and nasal allergies do the same thing. Flying while congested is the single biggest risk factor for significant ear pain.
Children are especially vulnerable. Their Eustachian tubes are shorter, narrower, and more horizontal than an adult’s, which makes it harder for air and fluid to move through. This is the same reason kids get more ear infections in general, and it’s why babies often cry during descent. They can’t intentionally equalize, and their anatomy is working against them.
Techniques That Help Equalize Pressure
The goal of every equalization technique is the same: force the Eustachian tube open long enough for air to pass through. The two most widely recommended methods are straightforward.
The first is to pinch your nostrils shut, close your mouth, and gently blow as if you’re trying to push air out through your sealed nose. This increases pressure in the back of your throat and nudges the Eustachian tube open from below. The key word is “gently.” Blowing too hard can cause damage.
The second approach is to pinch your nostrils shut and swallow at the same time. Swallowing naturally opens the Eustachian tube, and blocking the nose directs the pressure change toward the middle ear. Research comparing these two techniques in healthy volunteers found them equally effective, each succeeding about 52% of the time per attempt. That sounds modest, but in practice, people repeat the maneuver multiple times during descent, and cumulative success is much higher.
Simpler options work too. Chewing gum, sucking on hard candy, or sipping water all promote frequent swallowing. For infants, nursing or sucking on a bottle or pacifier during descent serves the same purpose. Yawning, even forced yawning, can also pop the tubes open.
Decongestants and Timing
If you’re flying with a cold or allergies, an oral decongestant or nasal spray before the flight can shrink swollen tissue around the Eustachian tube opening. Timing matters. On a long flight, Johns Hopkins Medicine recommends taking a second dose at least an hour before landing so the medication is active during descent, which is when equalization is hardest. A nasal spray works faster than a pill, so it’s more useful for shorter flights where you don’t have an hour of lead time.
Do Pressure-Regulating Earplugs Work?
Specialty earplugs marketed for flying contain a small ceramic filter that slows down the rate at which outside pressure changes reach your eardrum. They don’t block the pressure change entirely. Instead, they delay it, giving your Eustachian tube more time to catch up. In a double-blind pressure chamber study, these earplugs delayed maximum pressure reaching the ear canal by about 7 minutes. They didn’t improve Eustachian tube function itself, but participants wearing them reported significantly less discomfort during sudden pressure changes compared to those without them.
These earplugs are inexpensive and widely available at pharmacies and airport shops. They’re a reasonable option for people who consistently experience discomfort despite swallowing and other techniques, though they work best as a complement to active equalization rather than a replacement.
When Pain Doesn’t Go Away After Landing
Most ear discomfort clears within minutes to a few hours of landing as pressure gradually equalizes on its own. If pain persists for more than a day, or if you notice significant hearing loss, fluid draining from the ear, or ongoing dizziness, the eardrum may have ruptured. This sounds alarming, but most ruptured eardrums heal on their own within a few weeks. Some take months. During healing, keeping the ear dry and avoiding further pressure changes is important.
In rare cases where the tear doesn’t close naturally, a surgical repair called tympanoplasty can fix it. A surgeon patches the hole using a small piece of your own tissue, and the procedure is done on an outpatient basis. Full ruptures from flying are uncommon, though. The vast majority of people who experience ear pain on a plane are dealing with temporary barotrauma that resolves without any treatment.
