Yes, and especially adult-only airlines!
Yesssssssssssssssssssssssssssss!
I'd pay double for that if it was dog friendly!
When I used to travel a lot with my dog, every time I was stuck on a flight with some kid screaming or crying for the entire duration of the flight while I knew my quiet, well behaved dog was stuck in cargo, I always thought those kids should be down there instead and my dog, damnit. Send the parents down there too if they complain, I don't care. It should not be determined by species but by behavior. Good kids and good dogs who get a good behavior certificate are welcome in the cabin. Don't have a good behavior certificate? Too bad, so sad, wear a warm sweater and I'll see ya when we land.

oh if only wishes came true.
But when it's a baby crying (and not a toddler having a tantrum), I always try to be tolerant because I remember a friend of mine telling me of her experience flying back from Asia with a baby to bring her to the Amish family in the US who had adopted her (but obviously couldn't fly there to get the baby themselves) and the baby cried the ENTIRE flight, some 10+ hours and she said she just wanted to die.

lol At some point, an old lady took the baby for a while to give her a break (and avoid total emotional breakdown) and she said she just sat in her seat, with her sweater over her head, just crying. LOL That sounds like hell. But yah, babies is something entirely different than spoiled kids having tantrums.
I have to say that flying is pretty much the only time I'm really bothered enough for it to make a difference. Maybe restaurant, I guess. But it's still not as bad as a plane where there really is nowhere to go, sometimes for many, many, many hours. lol
