When my daughter was young. Angel Flight
Flew us 20 times between about five years.
They are so caring and you can catch a ride with a pilot if your going their way. We would fly from Las Vegas to Salt Lake City. Shriners hospital was also helpful. They flew me at least ten times for my care.They were always wanting to help anyway possible. 
I’m going to ask a friend if he does something like this here in the South, he absolutely loves helping others and he loves to fly, thanks!
