Try the Valsalva maneuver: pinch your nose, close your mouth, and blow gently to equalize pressure. Yawning, chewing gum, or swallowing also help. If discomfort persists beyond a few hours, a nasal decongestant spray may bring relief. Severe or lasting pain warrants a visit to a doctor or ENT specialist.
Your ears block because cabin pressure drops as the plane climbs — and your eustachian tube, a small channel connecting your middle ear to your throat, struggles to keep up. Commercial planes cruise at around 35,000 feet but pressurize the cabin to feel like 8,000 feet. That 5,000-foot pressure shift happens fast during takeoff and landing, trapping air in your middle ear. Most flyers feel mild discomfort, but roughly 10% experience real barotrauma — genuine pressure injury. You'll notice fullness, muffled hearing, or a dull ache. The good news: it's completely normal and almost always resolves on its own. Knowing how to nudge it along makes landing a lot more comfortable.
Descent is the danger zone. Cabin pressure rises quickly on the way down, and your ears have to work fast to catch up. If you're already congested from a cold or allergies, your swollen eustachian tubes make that job much harder. Flying with a sinus infection — say, boarding a red-eye with a head cold you thought you could push through — can mean ear pain that lingers for hours after you've grabbed your luggage. Long flights add another layer: more time for fluid to build up inside the ear. Babies and young children tend to suffer the most because their eustachian tubes are shorter and narrower, which is why you'll hear crying during descent on almost every family flight. Adults with a history of ear infections or chronic sinus trouble usually feel it harder too. Even a healthy flyer can wake up blocked if they fall asleep during descent — sleeping means no swallowing, and swallowing is your ear's built-in pressure valve.
Look, most people blame altitude for the pain. It's actually the pressure change doing the damage, not how high you are. Some think you need days for blocked ears to clear. Nope, most resolve within a few hours if you use the right technique. Then there's the idea that popping once fixes it. You typically need to equalize pressure multiple times during descent. Many assume decongestants prevent the problem if you take them before flying. They help if you're already congested, but they won't stop barotrauma in healthy ears. Ear drops sound helpful but don't actually fix the pressure imbalance in your middle ear. And plenty of people think ear fullness after landing means permanent damage. It doesn't, though really severe cases deserve a doctor's attention.
Most people feel relief within 30 minutes to a couple of hours using pressure-equalization techniques. If blockage lasts beyond 24 hours or causes sharp pain, it's worth seeing an audiologist or ENT doctor. In some cases — especially if fluid has built up behind the eardrum — symptoms can drag on for a few days.
Yes, it works exactly the same way on the ground. That said, starting it during descent is far more effective — doing it every 5 to 10 minutes as the plane drops altitude prevents blockage from building up in the first place. There are no side effects from repeating it, so don't be shy about it.
Use it about 30 minutes before descent so the swelling in your nasal passages has time to go down before the pressure shift hits. Spraying after you land is mostly too late — the blockage has already set in. If you're congested when you board, start the spray several hours before takeoff to get ahead of it.
