Your ears hurt during a flight because the air pressure inside the cabin changes faster than your body can adjust. A narrow tube connecting your middle ear to the back of your throat, called the eustachian tube, is supposed to keep pressure balanced on both sides of your eardrum. When a plane climbs or descends rapidly, that tube simply can’t keep up, and the pressure mismatch pushes your eardrum inward or outward. The result is that familiar, sometimes agonizing, pain.
This is common. Between 8% and 17% of passengers experience some degree of ear barotrauma after descent, and children are hit much harder: roughly 55% of kids report ear pain on flights compared to about 23% of adults.
What’s Happening Inside Your Ear
Your middle ear is a small, rigid, air-filled chamber sitting just behind your eardrum. The only flexible wall in that chamber is the eardrum itself. When cabin pressure drops during ascent, the air trapped in your middle ear expands. When the plane descends and cabin pressure rises again, that air compresses. In both cases, the eardrum gets pushed in one direction or the other because the pressure on each side is no longer equal.
Under normal conditions, the eustachian tube opens briefly every time you swallow or yawn, letting a tiny puff of air pass between your throat and your middle ear. That’s enough to keep things balanced in everyday life. But during a flight, pressure can shift so quickly that your eustachian tube doesn’t open often enough or wide enough to compensate. The eardrum bows under the pressure difference, stretching the delicate tissue and triggering pain. Descent is typically worse than ascent because the tube has a harder time letting air back into the middle ear when outside pressure is rising.
Why Some People Get It Worse
Anything that narrows or blocks the eustachian tube makes equalization harder. A head cold, sinus infection, or allergies can swell the tissue around the tube’s opening, effectively sealing it shut. The CDC notes that air pressure changes during flight can facilitate sinusitis and middle ear infections in travelers with pre-existing eustachian tube problems.
Children are especially vulnerable for a structural reason: their eustachian tubes are shorter, narrower, and more horizontal than an adult’s. That geometry makes it harder for air and fluid to move through, which is the same reason kids get more ear infections in general. On a plane, it means they’re less able to equalize pressure and more likely to feel significant pain.
Other factors that raise your risk include recent ear surgery, chronic ear problems, and simply having naturally narrow eustachian tubes. If you’ve had painful flights before, the pattern tends to repeat because the underlying anatomy doesn’t change much.
How to Equalize Pressure During a Flight
The simplest approach is swallowing frequently during ascent and descent. Chewing gum or sucking on hard candy works for the same reason: the swallowing motion tugs the eustachian tube open. For babies and toddlers who can’t do this on command, nursing or drinking from a bottle during takeoff and landing encourages the same action.
If swallowing alone isn’t enough, you can try more deliberate techniques:
- Valsalva maneuver: Pinch your nostrils shut and gently blow through your nose, as if trying to push air out. You should feel a soft pop as air enters the middle ear. Don’t blow hard, as too much force can cause damage.
- Toynbee maneuver: Pinch your nostrils shut and swallow at the same time. The swallowing opens the eustachian tubes while the closed nose compresses air against them.
- Frenzel maneuver: Pinch your nostrils, close the back of your throat as if you’re about to lift something heavy, then make a “K” sound. This pushes the back of your tongue upward and forces air into the eustachian tubes.
Start these techniques as soon as you feel the plane begin its descent. Don’t wait until your ears already hurt. Once the eardrum is already bowed significantly inward, equalizing becomes much more difficult.
Decongestants and Filtered Earplugs
If you’re flying with a cold or congestion, an over-the-counter nasal decongestant spray can shrink the swollen tissue around your eustachian tubes and give them room to function. Johns Hopkins Medicine recommends taking a decongestant before boarding and, on longer flights, again at least an hour before landing. If you have high blood pressure or heart problems, check with your doctor before using decongestants.
Pressure-regulating earplugs are another option. These contain a small ceramic filter that slows the rate at which air pressure reaches your eardrum. In pressure chamber testing, these plugs delayed the full pressure change by about 7 minutes, giving your eustachian tubes more time to catch up. They don’t block the pressure entirely, but they reduce the speed of the shift, which is often enough to prevent pain. You can find them at most pharmacies, often marketed for air travel.
Why Descent Hurts More Than Takeoff
Most people notice the worst pain during landing, not takeoff. During ascent, air in the middle ear expands and tends to push its way out through the eustachian tube relatively easily, sometimes with an audible pop. During descent, the process reverses: cabin pressure rises, the eardrum gets pushed inward, and air needs to flow back into the middle ear. The eustachian tube’s anatomy makes this direction harder. It functions a bit like a one-way valve that opens more readily outward than inward. That’s why active techniques like the Valsalva maneuver matter most in the last 20 to 30 minutes of a flight.
When Ear Pain After Flying Needs Attention
Mild fullness or muffled hearing after landing is normal and usually clears within minutes to a few hours as your eustachian tubes gradually equalize. Continuing to swallow, yawn, or use the Valsalva maneuver after landing can speed this along.
In rare cases, the pressure difference can rupture the eardrum. Signs of a rupture include sudden sharp pain followed by relief, fluid or blood draining from the ear, noticeable hearing loss, intense ringing, or dizziness. A ruptured eardrum often heals on its own within a few weeks, but it needs medical evaluation to rule out infection and confirm healing. If your symptoms persist for more than a couple of days, or if you develop a fever, significant hearing loss, or severe dizziness after a flight, those are signs that something beyond routine pressure discomfort is going on.
