There will be walls and curtains separating the “Only Adult” zone from the rest of the plane, making it ideal for travelers without children and business travelers who “want to work in a quiet environment,” according to a press release. 

As if the flimsy curtain is going to do anything, haha. You could technically have a baby as close as the row behind that. And you can already hear babies crying from across the plane anyways, especially as we trend towards smaller, more efficient planes like the 737 max and extended range 320s.
