Conventional wisdom is that screaming children are the quickest way to ruin a flight. Personally, I feel more empathy for the parents than anything else because we’ve been there multiple times. Our last flying experience revealed, though, that there is something more annoying by an order of magnitude: drunk college kids on a flight to Las Vegas for Spring Break. They’re just as loud, just as obnoxious, but they have the additional downside of being old enough to know better.
I’ve never been more thankful for noise-cancelling headphones and a smartphone full of movies.
