Great perspectives, I don't think the tickets or the GA would b aware of her age, but in any event, I do agree tht notifying the GA in DFW that the seat in F will not be used and that the passenger that occupied that seat will not be traveling on that leg. I don't suspect the GA will care as they now get an empty seat to fill. We will be on the phone and in visual contact with G-Ma at the gate so the hand off should be simple. My concern has been the rest of us 4 will have any issues with a missing member of our group while boarding.
