Honestly, I will never wrap my head around how people can happily bring infants on any flight where you can expect people to try and sleep, it’s incredibly lucky if they don’t spend some of it screaming their heads off—I would be mortified if my choices were preventing hundreds of people from sleeping. But I’m not going to rant too hard about that.
Why on earth hasn’t any airline started marketing adult-only flights?
It seems like a complete no brainer to me, I would choose it every time and pay extra for it.

Not gonna pile up any more than others already have lol. But to answer your question, airlines don’t do it because it’s just not feasible at scale. You say you’d gladly pay extra but then you’ll get a flight 50% cheaper and you’ll think “eh I’ll take the risk”. Or maybe you won’t, but a lot of people will. Planes are expensive and they have to consistently fill them as much as possible, which they won’t if they exclude such a vast demographic.
I mean, it’s technically feasible, but then you’d have to pay 5 or 6 times the price to cover for empty seats.
