Narrower-than-average tubes, recent ear surgery, or existing earwax buildup can worsen the sensation. Immediate Relief During a Flight Airplane ear - Symptoms & causes - Mayo Clinic
Here’s the cruel biology: the Eustachian tube is designed to let air out easily (like a one-way valve), but letting air in requires active muscle work—specifically, the tensor veli palatini muscle, which you activate when you yawn or swallow. If that tube is swollen from allergies, a cold, or even just narrow by anatomy, it collapses under the rising outside pressure. The tube acts like a wet straw. You can’t push air up .
In that case, consider a chronic condition. See an ENT. Options exist: balloon dilation of the tube, special pressure-regulating earplugs (like EarPlanes), or even a myringotomy (a tiny tube surgically placed in the eardrum) for frequent flyers.
The next time your ears block on a plane, don’t curse the wax. Thank your ancient, imperfect anatomy. And start the Valsalva—gently—before the runway lights appear.

While most cases resolve on their own, a persistent blockage can cause muffled hearing, pain, or even potential damage to the eardrum if not addressed. Why Ears Get Blocked on Planes
