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.
Disclaimer: I may or may not be on a 36h day with only an hour of sleep right now
There’s a spectrum, you can always charter a jet, and only allow other adults to join you on the charter. But that’s expensive.
As you pull in more and more strangers, you have to accept a broader spectrum of people’s lifestyles, including they need to move children.
From an airline perspective, it wouldn’t be a good look if you were excluding parents, so it would be a PR nightmare. Most people belong to families, even if they don’t have kids themselves, so a bad experience any member of their family had could reduce the amount of popularity your airline enjoy
However, it would be nice if airlines said, the back of the plane is the safest for children, which statistically it is, so children are only allowed to sit in the last 10 rows of the flight. That would be amazing
That would mean additional logistics and therefore costs for the airlines. So, no. As long as people accept being squeezed into cattle class and treated like cattle, the airlines have no incentive to change.
