Why Do Ears Pop on a Plane?

Last updated: April 2026

You're climbing through the clouds, the aircraft is accelerating down the runway and then lifting off, and within minutes you feel it — a pressure in your ears, a muffled quality to sound, maybe a slight ache. Then, often with an audible pop or click, your ears "pop" and everything suddenly sounds clear again.

This is one of the most universally experienced aspects of flying, yet surprisingly few people understand why it happens. If you've ever wondered why your ears pop on a plane — and what you can do about it — this is for you.

Why Do Ears Pop on a Plane?

Your ears pop because of a pressure difference between the inside of your ear and the outside air around you.

Here's how it works. Inside your middle ear — the space behind your eardrum — there's a pocket of air at the same pressure as the environment you're currently in. When you're at ground level, that pressure matches the air pressure outside your body. Everything is balanced.

When an aircraft climbs, the outside air pressure drops rapidly. At 30,000 feet, the air pressure is roughly one-third of what it is at sea level. But the air trapped in your middle ear is still at the higher ground-level pressure. The pressure inside your ear is now higher than the pressure outside, and this difference pushes against your eardrum, creating that uncomfortable feeling of fullness or pressure.

Your ears "pop" when the pressure equalises — when the trapped air in your middle ear finds a way to escape and match the lower outside pressure. That pop you hear and feel is the sudden release of that pressure difference.

The same thing happens in reverse when you descend. The outside pressure increases, and now the air in your middle ear is at a lower pressure than the surrounding cabin. Air needs to flow into your middle ear to equalise, which is why descending often feels worse than climbing.

The Eustachian Tube: The Key to Understanding Ear Pop

The structure responsible for equalising pressure in your ears is called the Eustachian tube — a small passage that connects your middle ear to the back of your throat (your nasopharynx).

The Eustachian tube is normally closed. It opens when you swallow, yawn, or chew, allowing air to flow in or out of the middle ear and equalise the pressure. This is why swallowing or yawning makes your ears pop.

In most people, the Eustachian tube opens easily and frequently enough that pressure equalisation happens almost automatically during a flight. But for some people — particularly during descent, when equalisation requires air to flow into the middle ear — the tube doesn't open easily enough, and the pressure difference builds up, causing discomfort.

Why Does Descent Feel Worse Than Climb?

Most people find that ear pressure is more uncomfortable during descent than during climb. There's a simple physical reason for this.

During climb, the higher-pressure air in your middle ear pushes the Eustachian tube open from the inside, making it easier for air to escape and equalise. It's like a balloon expanding — the pressure inside pushes outward, opening the door.

During descent, the higher-pressure air outside needs to flow into your middle ear, which requires the Eustachian tube to open and let air in. This is more difficult because the pressure differential is working against you, pushing the tube closed. It's like trying to inflate a balloon when the air outside is being squeezed against it.

This asymmetry is why your ears often feel fine during takeoff and climb but become increasingly uncomfortable as the aircraft descends for landing.

What Makes Ear Pop Worse?

Several factors can make ear pressure more uncomfortable during a flight:

Congestion: A cold, allergies, or sinus infection can block or narrow the Eustachian tube, making it much harder for air to flow in and out of your middle ear. This is why ear discomfort is often worse when you have a cold, and why flying with a severe cold can be genuinely painful.

Anatomy: Some people simply have narrower or less responsive Eustachian tubes. This is often a natural variation and doesn't indicate any medical problem.

Rapid changes in altitude: Aircraft that climb or descend quickly create more rapid pressure changes, which give your Eustachian tubes less time to equalise. Most commercial aircraft have a fairly gradual climb and descent rate, but some regional aircraft or private planes may change altitude more quickly.

Sleeping: If you're asleep during descent, you're not swallowing as frequently, which means your Eustachian tubes aren't opening as often. This is why you might wake up on approach with noticeably blocked ears.

How to Prevent or Reduce Ear Pop

There are several proven techniques for making ear pressure more comfortable during a flight:

Swallow frequently

Swallowing opens the Eustachian tube and helps equalise pressure. Drink water, chew gum, or suck on hard candy during climb and especially during descent. The more you swallow, the more often your Eustachian tubes open.

The Valsalva manoeuvre

Pinch your nose, close your mouth, and gently blow as if you're blowing your nose. This forces air up through the Eustachian tubes and into your middle ears, equalising the pressure. Be gentle — blowing too hard can damage your eardrum.

The Toynbee manoeuvre

Pinch your nose and swallow. This combines swallowing (which opens the Eustachian tube) with nose-pinching (which creates a slight pressure change), helping air flow into the middle ear.

Yawning

Yawning naturally opens the Eustachian tubes. If you can't yawn on command, chewing gum or pretending to yawn can often trigger one.

Specialised earplugs

Filter-earplugs are specially designed earplugs that slow down the rate of pressure change reaching your eardrum, giving your Eustachian tubes more time to equalise. They're available from most pharmacies and are particularly helpful for frequent flyers or people who struggle with ear pressure.

Decongestants

If you have a cold or allergies, a nasal decongestant spray used 30 minutes before descent can help reduce swelling in the Eustachian tube and make equalisation easier. Oral decongestants can also help, though they take longer to work.

Important: Do not use decongestants if you have a medical condition that makes them unsafe (such as certain heart conditions or high blood pressure). Always check with a pharmacist or doctor first.

Can Babies and Children Get Ear Pain on a Plane?

Yes. Babies and young children are particularly prone to ear discomfort during flights because their Eustachian tubes are narrower and less developed than adults'. They're also less able to actively swallow or perform the techniques above to equalise pressure.

For babies: Feeding during climb and descent is one of the most effective strategies. The sucking and swallowing motion helps keep the Eustachian tubes open. A bottle or breastfeed during takeoff and especially during descent can prevent most ear discomfort.

For young children: Encourage them to swallow frequently during descent. Water, juice, or a snack can help. For older children, the Valsalva manoeuvre can be taught and demonstrated.

For infants: If a baby starts crying during descent, it's often because of ear pain. Feeding or offering a pacifier can help. If the discomfort is significant, a dose of children's paracetamol or ibuprofen (appropriate for the child's age and weight) before descent can reduce discomfort.

When Should You Worry?

For most people, ear discomfort during a flight is a minor nuisance that resolves within minutes of landing. But in rare cases, the pressure difference can cause more serious problems:

Barotrauma: If the pressure difference is large enough and persists long enough, it can cause actual damage to the eardrum — a condition called barotrauma. Symptoms include persistent pain, hearing loss, or ringing in the ears that lasts more than a few hours after landing.

Perforated eardrum: In very rare cases, a significant pressure difference can cause the eardrum to tear. This is extremely uncommon in commercial aviation and almost always associated with pre-existing congestion or a condition that severely blocks the Eustachian tube.

If you experience persistent ear pain, hearing loss, or ringing after a flight, see a doctor. But for the overwhelming majority of people, ear discomfort during a flight is nothing more than a temporary annoyance.

Can You Avoid Ear Pop Altogether?

Not entirely. As long as you're flying at altitude, where air pressure is significantly lower than at ground level, there will be a pressure difference that your ears need to equalise. But with the techniques above, you can make it virtually painless.

The single most effective strategy is to stay active during descent — swallow, chew, or yawn frequently. Most people who struggle with ear pressure do fine if they simply stay conscious and active during the descent rather than sleeping through it.

Can Plane Tracking Help?

Knowing what's happening with your aircraft's altitude can give you useful context for when to expect ear discomfort. If you're at the airport watching planes approach, or if you're on the ground and can hear an aircraft circling before landing, a plane tracking app will show you the aircraft's altitude and rate of descent.

What Plane shows you the nearest aircraft in real time, including altitude, speed, and heading. If you're trying to spot the aircraft that your friends or family are on, or if you're just curious about the planes approaching the airport, the app gives you all the information you need — including exactly how high they are and whether they're climbing or descending.

Understanding the altitude profile of a flight can help you anticipate when ear pressure is most likely to build up. If you see an aircraft descending rapidly from 10,000 feet, you know the ear-popping phase is about to begin.

Frequently Asked Questions

Why do my ears feel blocked after a flight? This is usually because the Eustachian tube hasn't fully reopened after the flight. It typically resolves on its own within a few hours. Swallowing, yawning, and staying hydrated can help. If it persists for more than a day, see a doctor.

Can ear pop cause hearing loss? Not in normal circumstances. The pressure differences during a commercial flight are not large enough to cause permanent hearing damage in a person with normal ear function. If you experience hearing loss after a flight, it's usually temporary and resolves within hours.

Why do my ears pop in an elevator or car on a mountain? The same mechanism. Any rapid change in altitude — whether in an aircraft, elevator, or car — creates a pressure difference between your middle ear and the outside environment. The Eustachian tube opens to equalise the pressure, and you feel the pop.

Is ear popping more common on short flights or long flights? It's about altitude change, not flight duration. A short flight that climbs to 35,000 feet and descends will cause just as much ear popping as a long flight that climbs to the same altitude. The discomfort is most noticeable during climb and descent, not during the cruise portion of the flight.

The Bottom Line

Ear popping on a plane is a completely normal physical response to changes in air pressure. It's caused by the difference between the pressure inside your middle ear and the pressure in the cabin, and it resolves when your Eustachian tubes open to equalise the pressure.

It can be uncomfortable, particularly during descent, but it's rarely serious and is easily managed with simple techniques like swallowing, chewing gum, or the Valsalva manoeuvre.

If you understand why your ears pop on a plane, the next time it happens, you won't worry — you'll just swallow, wait for the pop, and carry on.
