Thank you for the tip FAN2502.

The trouble is that my mother refuses to sit in a wheel chair. There is a worry that this will be the begining of sitting in the wheel chair...old people and their superstitions.

But is there some kind of "unaccompanied minor" type of service for elderly person? I can put my mom on Business class. UNfortunately, First will really be breaking my back.

If there is not, then I guess I have to talk to my mother about considering using the wheel chair for once.
