Delta Air Lines

Margaret left for Houston to visit with Jo.  Left Knoxville 11:40 am.  Arrived at Atlanta.  Had an hour to change planes.  I was suppose to have a wheelchair and then they decided to transport me on a shuttle bus.  Made me late for my flight out.  Took the next plane 2 hours later.  Had to go to a different airport.  Clerk at airport called Jo and told her the change.  Got to Houston about 6:00 pm.
