As a "goodwill" gesture?? This makes it sound like she is lucky they might be providing any sort of compensation at all to her. Seems to me that she is due a full refund, since her son was not able to use the seat that she paid for. I don't think the article reveals the age of the child, as I think that would provide some bearing as to the airline's responsibility to provide full refund or not? Once again, airlines (or is it just United) making boneheaded decisions.
