It's not still relevant because a baby and a dog are not equivalent. A baby has rights a dog doesn't. A baby might disturb people, so might an adult, but both are humans and you have to take the risk of being disturbed by humans because society is made of humans. Society is not made of or for dogs. Dogs are optional.

The OP was not talking about small pets, which are already allowed. They're talking about buying a separate seat for a large dog. It is utterly insane to expect anyone to spend a cross-country flight with an 80lb Labrador next to them slobbering all over them.

Fair points! That said, I think I'd personally pay a small premium to sit next to someone's (well behaved) dog lol
