From Ananova......
"American Airlines is facing a £7 million lawsuit after a 70-year-old Alzheimer's patient vanished while changing planes at Dallas-Fort Worth airport.
Margie Dabney has not been seen since she vanished in December. Her husband Joe blames the airline for gross negligence and incompetence in her disappearance.
The couple, from California, were heading from Indianapolis to Los Angeles when they stopped at the airport to change planes".
In their defence, I guess American could say....they forgot!!!
