I think the airline made a mistake by not removing them and ignoring them. This is the kind of kid that I could never tolerate. Amazing how kids today seem to just rule the parents. This is like paying for a night out at a restaurant and having a spoiled brat seated next to you or near you. I have gotten up and told the parents to please be gracious enough to remove the brat so we could enjoy our meal only to be told off in no uncertain terms.
