I think the point remains, though, that making it harder to ensure a young child is sitting next to their guardian benefits _no one_. Having learned over the last year what flying with a 2 year old is like, an increase in the amount of toddlers who fly without sitting next to their parents is just going to be a nightmare for the kids, the parents, the other passengers, and the crew. No one should want this, in my opinion. Besides, the parents have the leverage in this situation I think, in the form of feral toddlers hell bent on maximizing chaos (and I mean that lovingly and empathetically, but still vaguely as a threat lol)
