lesschumras,
Here’s a problem. Let’s say the children free zone is row 10 to 20. If your sitting in row 20, you’ll still hear a screaming child in row 21
$15 fee to guarantee that your row is adult only and put that pay bracket on the border rows. $30 fee to guarantee that your row and the rows in front of and behind you are adult only. Put that pay bracket in the rows between the border rows.
C’mon, think like an airline exec! 🙂
