Does the airline charge less because yr child is a child or do you still pay the same amount because he takes up a seat. I don't care how much you straighten/clean as a neatnick. An extra person in a cabin creates more work. More towels to replace. More toothpaste drips to clean up. More garbage to empty. Did your child not take a seat a paying/tipping person could have utilized in the dining room? Do you not tip for your child's meal at a resturant at home or do you only go to McDonalds? The service/ wait staff is 99% dependent on tips to support their families.
