Short answer. From very recent and personal experience, Yes. Of course I was wondering the same thing, and a doctor and other healthcare provider told me 3 days before my flight that "it would really hurt." Another friend warned that my ear drums might pop. At the time I went to the doctor both ears were blocked and I was having ear pain, so I was prescribed antibiotics. The next morning, one of my ears was leaking fluid, so I was really glad I had the antibiotics, which promptly cleared up both the ear pain and the secretions, but, alas, not the blocked Eustachian tubes. Three days later, I got on an airplane expecting the worst. I did take Sudafed decongestant before getting on, which helped my nasal passages but didn't touch the ear blockage. Well, "all" that happened as the plane ascended was a fireworks display going off in my ears! Lots of popping and cracking, but fortunately no pain. And it was that way for 3 more flights. Now, 2 weeks later I still have the blocked ears, but the pain has not returned.
The Eustachian tubes
The Eustachian tube connects the middle ear to the throat. Its main function is to help equalize air pressure on both sides of the eardrum, which is important for proper hearing and balance. If the Eustachian tube is blocked or dysfunctional, it can lead to ear pain and hearing problems.
The Eustachian tube is located within the human ear. If the Eustachian tube is blocked, air is prevented from passing through to the middle ear.

Those are called the Eustachian tubes.
Nasopharynx
Eustachian tubes
The eustachian tubes are the auditory tubes that link the nasopharynx to the middle ear.
Ear tubes or grommets, are used in children to help alleviate persistent infections caused by a blockage in the Eustachian tubes. These blockages can be caused by large adenoids, or blocked nose/sinuses caused by viral infections or allergies.
Eustachian tubes are part of our auditory system their function is to equalize pressure on both sides of our ear drum so that it can vibrate freely.
Salpingostenosis is the medical term meaning abnormal narrowing of the eustachian tube. The breakdown is salpingo- (tube - usually eustachian or fallopian) and -stenosis (abnormal narrowing).
