Soooo, she was with family. The point is, you are trying to make out like US Airways canceled a flight and left her stuck in some airport for days. That is not the case. The fact is you booked the ticket for certain dates, then wanted to change. You are then liable for the change penalties if you make the change. If things wrapped up early, why are you not griping about the filming company stranding her?

I'd be more upset with my sister then the airline. Some Aunt hopefully she is off the xmas card list.
