If the child had an ear ache, understandable.. that's pain.. but that still is not throwing oneself onto the ground of the isle and throwing a temper tantrum.
If the child had an ear infection than the parents should not have put her on the plane in the first place. They should have taken her to a doctor for treatment then either waited in Florida for her to improve, taken the train or bus or driven. But this plane never got off the ground because the brat war crawling under the seats, hitting her parents, etc.
