Ear Pain on a Flight: Why It Happens and How to Ease It

Ear pain during flight is a familiar complaint after a holiday or a work trip: the ear feels fuller and fuller as the plane comes down, an ache sets in, and everything sounds muffled for a while after landing. Most of it is pressure rather than infection, and most of it settles on its own. This article explains what is happening inside the ear, what helps during take-off and landing, and which after-flight symptoms are worth having examined.

Symptom

The pattern is usually the same. Take-off is fine, or brings a gentle popping. The trouble starts as the plane begins its descent, sometimes half an hour before landing: a growing fullness in one or both ears, then a dull ache that can sharpen into real pain. Sounds go muffled, your own voice seems louder inside your head, and swallowing produces clicks as the ear tries to clear itself.

For most people the pain eases within minutes to hours of landing, and the blocked feeling clears over a day or two. Some notice it lingering for a week, particularly after flying with a cold. Babies and small children often cry through the descent because they cannot clear their ears deliberately. Flying with a blocked nose, and sleeping through the descent, both make an episode more likely.

What is actually happening

Behind the eardrum is a small air-filled space, the middle ear. Its only connection to the outside is the Eustachian tube, a narrow passage running to the back of the nose. The tube stays closed at rest and opens for a fraction of a second when you swallow, yawn or sneeze, letting a puff of air in or out so the pressure in the middle ear matches the pressure around you¹.

On the way up, cabin pressure falls. The air in the middle ear expands and escapes down the tube by itself, so climbing usually causes nothing worse than a pop. On the way down, cabin pressure rises, the eardrum is pushed inwards, and air has to be let in through the tube. That needs an active step, a swallow or a yawn, rather than happening on its own². This is why ear pain during flight almost always belongs to the descent.

If the lining of the tube is swollen by a cold or an allergy, it may not open at all, and the stretched eardrum starts to hurt. Once the pressure gap is large enough, the tube can be pressed shut so firmly that swallowing no longer opens it, which is why clearing the ears early and often during the descent works far better than trying hard once the pain has arrived². A middle ear left at low pressure for long enough draws fluid, and occasionally a little blood, out of its lining, and in a severe episode the eardrum can tear. Doctors call this ear barotrauma².

What helps during take-off and landing

• Keep swallowing. Sip water, chew gum or suck a sweet from the moment the descent begins, not once the pain starts. Yawning helps too.
• Stay awake for the descent. Ask a companion or the crew to wake you.
• Use a gentle equalising move. Pinch your nose, close your mouth and swallow. If that is not enough, blow gently against the pinched nose until you feel a soft pop. Avoid forceful or repeated blowing, which can push pressure into the middle ear rather than balance it.
• For babies, breastfeed, bottle-feed or offer a dummy through the descent so the child keeps swallowing.
• If you have a cold and cannot postpone the trip, a decongestant tablet or nasal spray before the descent is thought to reduce the swelling around the tube and help it open¹. Decongestants are not suitable for everyone, including people with high blood pressure or heart disease and young children, so ask a doctor or pharmacist first.
• With an ear infection or a heavy cold, postpone the flight if you possibly can.

When it is worth having checked

Most flight-related ear pain needs nothing more than time and the measures above. Have the ear examined when:

• Pain has not eased within a day or two of landing, or is severe.
• Hearing is still muffled after one to two weeks, or feels genuinely reduced rather than just blocked. Fluid behind the eardrum can take weeks to clear, but it should be improving.
• Hearing dropped suddenly, or ringing or spinning dizziness began during or soon after the flight. These can point to the inner ear rather than the middle ear, and they need assessment the same day².
• There is blood or discharge from the ear, which can mean the eardrum has torn, or fever and worsening pain a few days later, which suggests infection. Keep the ear dry and have it looked at.
• It happens on every flight, or always in the same ear. A tube that fails every time is often held shut by something in the nose that can be treated.
• A child is pulling at the ear, has a fever or discharge, or seems not to hear well after the flight.

The World Health Organization lists ear infections, fluid in the middle ear, trauma to the ear and sudden hearing loss among the causes of hearing loss, and names the identification and management of common ear conditions among its strategies for reducing it³. A problem that persists after a flight is exactly that kind of condition.

What a visit involves

The consultation begins with a conversation: when the pain began in relation to the descent, whether you had a cold, whether it has happened on earlier flights or while diving, and whether hearing, ringing or balance has changed. The ear is then examined with an otoscope, a lit magnifier, to see whether the eardrum is pulled in, whether there is fluid or blood behind it, and whether it is intact.

Because the tube opens at the back of the nose, a persistent or recurring problem is usually also assessed with a small flexible camera passed gently through the nostril. It takes a minute or two and shows the nasal lining, any swelling from allergy or infection, and the opening of the Eustachian tube itself¹. Two quick tests may follow: tympanometry, which measures how freely the eardrum moves and the pressure behind it, and a hearing test if hearing has changed.

You are then told plainly what was found and what it means. For most people that is a middle ear recovering from a pressure injury, managed with time, a nasal spray if the nose is inflamed, and a plan for the next flight. A torn eardrum usually heals on its own with the ear kept dry and a follow-up check. Fluid that stays for many weeks, or a tube that fails on every trip, has further options once the cause is clear, and sudden inner ear symptoms are treated as a priority.
