Yeah shrieking before a flight is annoying for sure. But while they’re in flight and they scream, I feel sorry for them because the reason they are shrieking is that they’re in pain and they don’t know how else to express that feeling. I remember being extremely young and my ears being in pain because when you’re a child, the Eustachian tubes in the ears are vertical instead of slanted like adults are. Although it’s seriously annoying, I can’t help but empathize with them because their family may be taking a flight because they’re unable to drive or whatnot. We don’t know their situation, but I agree a childfree flight would be nice.
